Cognitive abilities differ between males and females and these differences are present from childhood. In broad terms, girls have stronger verbal skills than boys who tend to have stronger skills related to spatial ability (Linn and Petersen 1985). It is thought that the actions of sex hormones have a role in these differences. Reviewing different cognitive strengths of male versus female humans is not within the scope of this article but the idea that cognition could be altered by testosterone deserves attention.

However, studies have found that social success among men is actually linked with high testosterone levels. For example, teenage boys who were perceived as socially adept and dominant had higher levels of testosterone than boys that were low on the totem pole. What’s even more interesting is that this same study found that teenage boys who had a history of being anti-social and displaying high physical aggression were found to have lower testosterone levels at age 13 compared with boys with no history of high physical aggression.
There are pills in the United States for testosterone supplementation, but their use is strongly discouraged because they cause significant liver toxicity. A safe oral formulation called testosterone undecanoate is available in Canada and in Europe, but not in the United States. What’s quite exciting is that an injectable version of testosterone undecanoate (Nebido) was submitted to the FDA for approval in August 2007. (It’s already approved in many other countries.) It lasts for 12 weeks, so a patient could come in and get a shot about four times a year. [Editor’s note: In December 2009, the brand name of the drug in the United States was changed to Aveed. As of January 2011, it was still awaiting FDA approval.]
Most Americans today are sleep deprived, which may be a contributing factor to declining testosterone levels in men. See, our body makes nearly all the testosterone it needs for the day while we’re sleeping. That increased level of T that we experience at night is one of the reasons we wake up with “Morning Wood.” (If you don’t have Morning Wood on a consistent basis, you might have low T).
Cross-sectional studies have not shown raised testosterone levels at the time of diagnosis of prostate cancer, and in fact, low testosterone at the time of diagnosis has been linked with more locally aggressive and malignant tumors (Massengill et al 2003; Imamoto et al 2005; Isom-Batz et al 2005). This may reflect loss of hormone related control of the tumor or the effect of a more aggressive tumor in decreasing testosterone levels. One study found that 14% of hypogonadal men, with normal digital rectal examination and PSA levels, had histological prostate cancer on biopsy. It is possible that low androgen levels masked the usual evidence of prostate cancer in this population (Morgentaler et al 1996). Most longitudinal studies have not shown a correlation between testosterone levels and the future development of prostate cancer (Carter et al 1995; Heikkila et al 1999; Stattin et al 2004) but a recent study did find a positive association (Parsons et al 2005). Interpretation of such data requires care, as the presentation of prostate cancer could be altered or delayed in patients with lower testosterone levels.
It’s perhaps no coincidence that Giacomo Casanova, who was said to eat 50 oysters for breakfast each morning, reportedly bed half of Europe. After all, oysters are brimming with zinc, a mineral that elevates testosterone while simultaneously boosting growth factor hormone—both of which enhance muscle growth and physical performance (in and out of the bedroom).
I am 45 years old and have been diagnosed with low testosterone levels. In 2014 my levels were 16.5 and in 2016 that dramatically reduced to a score of 10.4. My doctor prescribed me Testo gel which I rub on every morning and have done so for the last 6 weeks. I keep myself fit, gym twice a week and martial arts twice a week and found my energy levels were depleting and didn’t seem to recover quickly the next day. I started to feel exhausted and experienced low libido,lack of motivation and mental focus. I actually thought oh well this is what happens when you get older.
I was depressed, getting fat, and zero libido. My doc did a full blood work up. My Total Testosterone level was 289 ng/dl. He offered TRT but I declined because I knew, at 53, that if I went on TRT my own testosterone production would shut down and at my age I would have a pretty difficult time kick starting it up again. I researched and researched for about a month. I started on Vitamin D 10,000 iu per day ( I knew this was a safe amount because I tested at 26ng/dl and optimum level is anywhere between 40-80ng/dl. I also took 1,200 mg of magnesium, 9mg of Boron and Vitamin K Complex. Tested again 3 months later and blood work showed I was at 720.
I have been on TRT for over 8 years now. I feel GREAT! I read all these studies, hear in the news, and see all these dumb lawsuit commercials about testosterone causing cardiovascular events, blood clots and many other things. If anyone takes the time to do the due diligence and read the studies the picture becomes very clear. Unless you monitor all the other hormones, specifically, Estradiol, DHT, Pregenolone, Total Testosterone, Free Direct Testosterone, and DHEAS you are playing a deadly game. The reason is you must give something to control the pathways of T conversion into estradiol and or DHT. The vast majority of the studies used nothing to control those pathways and they gave men way, way more T than they needed to start with. They also gave forms of T that are not acceptable. Especially the oral version.
We scoured the database of the National Center for Biotechnology Information (part of the U.S. National Library of Science) for articles. Of the many ingredients marketed as boosting testosterone levels, we only found four backed by multiple articles based on human testing. For the best chance of boosting testosterone levels, a supplement needs to contain magnesium, fenugreek, and longjack — and some zinc wouldn’t go astray, either.
The potential downside of this positive feedback loop, Coates argues, is that testosterone levels can eventually surge past optimal levels and have the opposite effect – leading to overconfidence and poor decision-making. When this happens to animals, Coates, observed, they “go out in the open, pick too many fights [and] patrol areas that are too large…Risk taking becomes risky behaviour.”

2009 had heart attack, placed coronary stent, everything okay. Put on statins to keep lipid levels down to prevent further artery blockage. One year later developed Peyronie’s disease, low sex drive, fatigue, testicles withdrawn and hurting. Testosterone level was 85. Diagnosed with hypogonadism. Started Androgel, felt normal after a couple of weeks. I believe statins is the cause of my low T, you need lipids for hormone transport. Androgel could only bring my T level in the 250 range. Switched to Axiron (better, less messy), and my T level stays around 500 range. I get samples of Testim every now and then, it has a manly woody fragrance that women like. At present, I’m feeling a little fatigue, and mild dehydration. My lab work is always normal, except my red blood cells is always on the high side, almost abnormal. Next week I am going to donate some blood, to bring my RBC count down, and see if that will help.

The regular intake of testosterone boosters is known for the high level of safety comparing to the hormone injections and the use of illegal steroids. But still to protect yourself against any possible adverse reactions, you should remember that the supplementation can’t be continuous. The breaks from time to time are required. Such an approach to the use of boosters is healthy and best-working if you aspire to enhance own hormone production without any harm.
Tongkat ali (a.k.a. Longjack, a.k.a. Eurycoma Longifolia) is a foundational compound of Ayurveda, commonly used as an aphrodisiac. Similar to DHEA, longjack has been found to be effective in both men and women for improving libido, total and free testosterone concentrations as well as muscle mass and strength in men and women! And, unlike many of the other old world herbs commonly touted as natural testosterone boosters, longjack actually has a fair amount of human research denoting its benefits.
It goes without saying that a healthy diet, quality sleep, productive lifestyle, and regular exercises can contribute to the overall increase of testosterone. However, it is also true that these activities are very often not enough for guys who have the problems with naturally low testosterone levels. This situation also includes people who want to boost their existing testosterone levels.
Now that we know chronic insulin spikes lead to lower Testosterone production, I hope I haven’t sent you running into the low carb camp! There are a few studies out there showing that long term low carb or ketogenic dieting leads to higher cortisol levels (especially with subjects who are training), and decreased testosterone levels (28 & 29). I have used low carb diets in the past with successful results (winning a national bodybuilding title), however the key is to use cyclical carb re-feeds. If you’re going to go on a low carb diet for whatever reason, be sure to work in a large carb reefed once a week.
Why is there no information on the increase of estrogen when on Testosterone replacement therapy? I have been on t replacement for about 2 years and over that time my balls have gotten to the size of a large grape. I have fatty tissue on my chest and my estrogen level is over 400. There needs to be a study created to test all of these side effects and posable treatments like estrogen lowering drugs and HCG for maintaining Testicle size.
Started HRT in my early 50’s as I had all the low-T symptoms and Type 2 Diabetes, which was hammering my body. My total T was about 100 (not sure about Free at that point). First started with Androgel, and was getting decent symptomatic improvement, but didn’t like the residue from the cream, and traveling with the creams was a problem. I’ve gone to pellet implants for the past 7 years. Every 4-5 months, very happy with results to date.

I am 35 and had the non sexual symptoms for awhile now( weight gain/muscle loss, extreme fatigue, lack of clarity/concentration) I got my testosterone levels checked last week and it was 35.4 ng. Not a typo, 35.4. I was told by my dr. That I needed to start TRT right away as low t can effect a lot different things in your body. I did my first injection last night (200mg/ml every 2 weeks) about 8 pm and td now 3:30 am and I’m wide awake and feel extremely motivated to go to the gym and work out. I know each person is different but should I feel like this already, or is it a placebo effect at this point?


Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T.[118] The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.

I’ll be 31 this year and my belly is getting out of hand. I’ve cut way way back on my soda intake to maybe one or two a day most days and I’m drinking way more water than ever. Seems this belly is here to stay lol. I’m working on a better diet and I’m also gonna start back working out. This belly is a serious drag I hate it and I need it gone asap. What’s gonna be my best option in a test booster. I don’t want t to get all crazy buying fat burning pills and other foolery but I thing a test booster will help me all around. I’m high anxiety low energy poor sleeping over eating father of 4 and im currently in barber school. I need to make changes for my family and myself as well as my profession. Please help. (Belly is my only problem area I’m 30yrs olf 6ft 180lbs)


Glad to be heard. I have been using 10 times the recommended prescription dose of injectable test over the course of 6 years. Yes, 10 times the recommended dose. I use 250 at the lowest and 1000 mgs a week and sometimes 1200 mgs weekly. I am 50 years old. I look better than 90% of the 25 year olds I see in the gym. I have had zero issues. Acne a little , testicle shrinkage maybe 15%. No big deal. My sex drive is on fire. I bench pressed 340 pound today. I weigh 195 pounds and lean and muscles defined and hard as a rock. Doctors in the USA have no clue what they are doing. They read literature and have no experience or facts about test. They prescribe 50 mgs a week. Way short of what we as men need. Everyone is different, but 250mgs weekly is what we need typically. Injectable is the way to go. Gels are a weak joke. My doctor basically told me he was scared to prescribe more than 50 mgs weekly for fear of being sued if something went wrong. I found my own source and have been on top of the world for 6 years. Father died of prostate cancer. Mine prostate is fine. Prostate cancer from test is another example of ignorance in medical field. I am living proof that one can inject 10 times the recommended rate for the better part of a decade with no probs. I do hope the medical field catches up with the times and stops relying on archaic info.
For example, the study published in Obesity Research tells that the scientists measured testosterone levels in two groups of middle-aged men with obesity. One group underwent a 16-week weight loss program, while the second group did nothing. Each participant of the first group lost 20 kg on the average. And these participants experienced a significant increase in testosterone levels. So, the fight against overweight is very important for those who want to overcome testosterone deficiency. But starvation is strictly forbidden because this is a stressful situation which leads to the sharp decline in T levels.
“What on earth do you mean?” Well, I don’t literally mean taking it to the compound. What I mean to say is that you should be incorporating the three most important compound exercises into your routine: bench press, squats, and deadlifts. In case you didn’t know, by training large muscle groups your body releases more testosterone. When you do these three lifts, and perform them properly, then you’ll reap the benefits of not only muscle gains, but also that of an increased release of testosterone and growth hormone.

Vitamin D, a steroid hormone, is essential for the healthy development of the nucleus of the sperm cell, and helps maintain semen quality and sperm count. Vitamin D also increases levels of testosterone, which may boost libido. In one study, overweight men who were given vitamin D supplements had a significant increase in testosterone levels after one year.5
There are a lot of test booster blends out there. A lot of them are junk. I have tried to cover the most effective herbs above. As always, I recommend doing your own research and experiment to see if you notice an effect. If you would like one easy herbal solution I recommend starting with Mike Mahlers Aggressive Strength product purely because I have solid anecdotal evidence of its effectiveness. But again, supplements should be seen purely as that - a supplement to a healthy diet, plenty of sleep, hard training with adequate rest.
You should also know that a lot of people are deficient in Vitamin D. In the USA & many other western regions in the world, vitamin D deficiency is at epidemic proportions. The best way to increase your D levels is sun exposure. You only need 20-30 minutes of exposure to a large amount of skin (i.e., take your shirt off and go for a walk during the day).
Hello..was prescribe andro gel 1.62 for about 2 years..borderline low..At time 54 year old now 57..a year ago switched doctors..new doctor would not prescribe andro gel..without me stopping use and then being checked after 6 months..it’s been a year..by the way felt great while on it much more energy. .did notice some hair receding. .but felt stronger..my question is..by using andro gel ..did I turn off my body’s natural ability to make testosterone as using andro gel..if so what do I need to do too turn my body on if my doctor does not renew therapy. .by way the past without andro gel…little too no energy..weight gain of 40 lbs..especially around the belly..thank you for your time and reply
If you have low testosterone, your functional medicine or anti-aging physician will help you diagnose it. There are several different hormones your physician should measure, but the most important two are your free testosterone and estrogen levels, because converting too much testosterone to estrogen is a problem that’s different from not making enough testosterone in the first place. In my case, I wasn’t making very much testosterone, and what I was making my body converted to estrogen way too effectively.
Some people can get away with more of a barebones approach to boosting their testosterone levels.  MET-Rx Tribulus 750 has been around for years and has been used by many to help get their testosterone levels back within the normal range.  The product has been laboratory tested and has been deemed safe for use by athletes, bodybuilders, and gym rats alike.

Side note, insurance rarely will cover it and cause a long paper trail to even approve it which is unfortunate and disheartening. Especially when it is done out of network. Currently I have found a place to supply all of the aboue sent to my house at approximately $200.00 per month. Still an unfortunate cost for a medical reason that the insurance companies don’t approve. Best of luck to all of you.
Everytime you add Testosterone to your system, be it naturally through producing in the testis, injected, oral, or dermal you will receive a spike in your blood levels. Estrogen is mainly created in men by an action of an enzyme called Aromatase. Aromatase floats around and binds to Testosterone and converts it to Estrogen. When you spike your T your E will follow in this way. The obvious and detrimental effects to many of the already estrogen dominant hypogonadal men will be inappropriate over stimulation of the estrogen receptors in the body. Gynecomastia, fluid retention, weight gain, brain fog, erratic emotions, depression, ect. Higher levels of Estrogen cause SHBG to be created. SHBG binds to Testosterone and transports it to the liver for disposal. On top of this Estrogen can bind to your androgen receptors causing Testosterone to float around with no where to go. If you are taking shots or gel or cream and feel little to no effect even though it’s technically raised your T blood ranges, you now have an multiple answers for why you little to nothing or feel even worse. This has been known for years that you must be prepared to control Estrogen. An Aromatase Inhibitor (AI) or anti estrogen medication (Clomiphene, Tamoxifen) is needed to stop the estrogen from getting out of control. By taking an Aromatase inhibitor and monitoring your E2 levels you can easily control Estrogen, Aromatase, and SHBG from getting out of hand and free up those blocked androgen receptors so you can now reap the benefits of elevating T to a healthy level. If your Doctor is not testing your E2(aka Estrogen, Estradiol) levels before and during talks and administration of TRT or will never prescribe an AI then you shouldn’t be following his advice at all and will be harmed by Testosterone usage. This may sound complicated but in the end it’s simple. Elevate Testosterone. Control Estrogen. Only two medications needed. Don’t settle.

Alterations in mood and depression are a symptom of, but not confined to, hypogonadism.1,6 Outcomes in clinical trials of the effect of testosterone treatment on mood have varied. However, there is evidence that testosterone treatment results in improvements in mood, particularly in older men with hypogonadism.7,8Similarly, although there is an established association between measures of cognitive ability and serum levels of testosterone, the benefits of testosterone treatment on cognition are less clearly established, with some studies reporting improvements in some measures of cognitive function and others failing to detect benefits.6,9-11 Although a potential role for testosterone in protecting cognitive function and preventing Alzheimer’s disease has been proposed by some researchers, confirmation from appropriately-designed clinical trials is awaited.

Because clomiphene citrate is not approved by the FDA for use in men, little information exists about the long-term effects of taking it (including the risk of developing prostate cancer) or whether it is more effective at boosting testosterone than exogenous formulations. But unlike exogenous testosterone, clomiphene citrate preserves — and possibly enhances — sperm production. That makes drugs like clomiphene citrate one of only a few choices for men with low testosterone who want to father children.
At the present time, it is suggested that androgen replacement should take the form of natural testosterone. Some of the effects of testosterone are mediated after conversion to estrogen or dihydrotestosterone by the enzymes aromatase and 5a-reductase enzymes respectively. Other effects occur independently of the traditional action of testosterone via the classical androgen receptor- for example, its action as a vasodilator via a cell membrane action as described previously. It is therefore important that the androgen used to treat hypogonadism is amenable to the action of these metabolizing enzymes and can also mediate the non-androgen receptor actions of testosterone. Use of natural testosterone ensures this and reduces the chance of non-testosterone mediated adverse effects. There are now a number of testosterone preparations which can meet these recommendations and the main factor in deciding between them is patient choice.

Attention, memory, and spatial ability are key cognitive functions affected by testosterone in humans. Preliminary evidence suggests that low testosterone levels may be a risk factor for cognitive decline and possibly for dementia of the Alzheimer's type,[104][105][106][107] a key argument in life extension medicine for the use of testosterone in anti-aging therapies. Much of the literature, however, suggests a curvilinear or even quadratic relationship between spatial performance and circulating testosterone,[108] where both hypo- and hypersecretion (deficient- and excessive-secretion) of circulating androgens have negative effects on cognition.

Testosterone strengthens bones. You may have thought of osteoporosis as a health problem that only women have to worry about, but men can suffer from this bone-weakening disease too. And low testosterone levels may be to blame. Testosterone has been shown to play an important role in bone health. It increases bone density by stimulating bone mineralization as well as decreases bone resorption. Elderly men suffering from osteoporosis typically have sub-optimal testosterone levels. If you want to enjoy strong, healthy bones well into old age, take steps to improve your testosterone levels now.
The general recommendation is that men 50 and older who are candidates for testosterone therapy should have a DRE and a PSA test. If either is abnormal, the man should be evaluated further for prostate cancer, which is what we do with everybody whether they have low testosterone or not. That means a biopsy. But if all of those results are normal, then we can initiate testosterone therapy. The monitoring that needs to happen for men who begin testosterone therapy is really very simple: DRE, PSA, and a blood test for hematocrit or hemoglobin, once or twice in the first year and then yearly after that, which is pretty much what we recommend for most men over age 50 anyway.
The changes in average serum testosterone levels with aging mean that the proportion of men fulfilling a biochemically defined diagnosis of hypogonadism increases with aging. Twenty percent of men aged over 60 have total testosterone levels below the normal range and the figure rises to 50% in those aged over 80. The figures concerning free testosterone are even higher as would be expected in view of the concurrent decrease in SHBG levels (Harman et al 2001).
Vitamin D is arguably the most important vitamin when it comes to testosterone. A study published in the Journal of Clinical Endocrinology examined the relationship between vitamin D supplementation and testosterone levels in men. The authors found that participants with higher levels of vitamin D had significantly higher levels of free testosterone compared to those with insufficient levels of vitamin D.8 Based on these study results, it appears vitamin D has a strong relationship with testosterone levels.

Today we take a look at some of the physical and psychological benefits that come with having optimal testosterone levels (I’ll talk about what “optimal” means regarding T later this week). You probably know about some of the benefits already, but some of the ones I discuss may surprise you. When appropriate, I’ll report any health benefits that I experienced during my own 90-day testosterone boosting experiment.
In 1927, the University of Chicago's Professor of Physiologic Chemistry, Fred C. Koch, established easy access to a large source of bovine testicles — the Chicago stockyards — and recruited students willing to endure the tedious work of extracting their isolates. In that year, Koch and his student, Lemuel McGee, derived 20 mg of a substance from a supply of 40 pounds of bovine testicles that, when administered to castrated roosters, pigs and rats, remasculinized them.[183] The group of Ernst Laqueur at the University of Amsterdam purified testosterone from bovine testicles in a similar manner in 1934, but isolation of the hormone from animal tissues in amounts permitting serious study in humans was not feasible until three European pharmaceutical giants—Schering (Berlin, Germany), Organon (Oss, Netherlands) and Ciba (Basel, Switzerland)—began full-scale steroid research and development programs in the 1930s.
I have used Androgel for 7 years with Testosterone levels between 650 and 900. PSA remained just under 3.0. 2 pumps per day. A year ago I increased my pumps to 4 per day and within a few months my Testosterone was 1,100 BUT my PSA shot up to 5.2. Last April, I totally stopped Androgel and within 2 months my Testosterone was under 20 (really) and PSA was virtually zero. Libido also fell from “strong” to “zero”. After 5 months of no Androgel, I resumed it in September at 2 pumps per day and now my Testosterone has improved to almost 600 and my PSA is just under 3.0. Am having my 3 month check-up with my Urologist tomorrow.

In contrast to steroids, testosterone boosters have a fully different mechanism of action. They are the products which contain the natural ingredients only. These ingredients act by stimulating the man’s body to synthesize own testosterone. So, testosterone levels grow naturally without negative health effects associated with the intake of steroids.
The testosterone booster pills are effective from 4 to 8 hours. To maintain testosterone levels high during the whole day, you need a multiple daily dosing regimen. 2-times daily dosing still not always can improve hormone production to the greatest extent. 3-4-times daily dosing is the best solution to make your body normalize testosterone synthesis and prevent it from decreasing before you take another pill. Don’t forget that the regularity of daily supplement intake is crucial if you really aspire to give a boost to hormone production.

If your levels are indeed low, there are a number of synthetic and bioidentical testosterone products on the market, as well as DHEA, which is the most abundant androgen precursor prohormone in the human body, meaning that it is the largest raw material your body uses to produce other vital hormones, including testosterone in men and estrogen in women.
The maximum hormone concentration in the blood is reported immediately after the workout. And the effect lasts throughout the day. However, it’s important to ensure that your physical activity is moderate. The matter is that too much high-intensity exercise can give an undesirable result. But even if for any reason you can’t attend a gym, it’s not a problem. Just move as much as possible during the day. Even simple walking will be of great benefit.
How alpha are you? Well, how many shakes of hot sauce can you handle? A recent study from France found men who have a taste for spicy foods tend to have higher testosterone levels than those who can’t handle the heat. Of the 114 male participants surveyed, researchers saw a clear correlation between frequent hot-sauce usage and higher T-levels. Study authors suggest the findings may be due in part to capsaicin—the fiery compound in chili pepper that previous studies have associated with increased testosterone levels. In animal studies, capsaicin has also shown to increase the size of sex organs, while simultaneously decreasing belly fatbelly fat. Yowza!
Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T.[118] The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.

In order to yield a consistent and efficacious form of shilajit, the shilajit is obtained from carefully selected rocks and is put through a patented technology where it is purified and standardized. This form of shilajit is now assured of optimal levels of bioactive components such as fulvic acid and dibenzo-pyrones, and is known as the patented PrimaVie.
There’s a significant failure rate of the PDE5 inhibitors for erectile dysfunction, something on the order of 25% to 50%, depending on the underlying condition. It turns out that a third of those men will have adequate erections with testosterone-replacement therapy alone and another third will have adequate erections with the pills and testosterone combined. There’s still a third who don’t respond, but normalizing their testosterone level has definitely rescued many men who had failed on PDE5 inhibitors.

I am a 67 yo male diagnosed with prostate cancer gleason 6. I have a prescription on bicalutamide 50 mg a day since Nov 2016 and leuprolide 11,5 mg every 3 months. My testicles reduced their size to half it´s original size, my libido is almost zero. I went through a radiotherapy of 45 sessions; my PSA level went from 11.2 to 0.13 on my last test from Sept 2017 and the leuprolide injections are taken away from my prescription by my urologist. I am planning to take TRT with Testosterone mix called SUSTANON 250 mg per week and HCG 5000 IUs twice a month. Give me your thoughts please


In addition to conjugation and the 17-ketosteroid pathway, testosterone can also be hydroxylated and oxidized in the liver by cytochrome P450 enzymes, including CYP3A4, CYP3A5, CYP2C9, CYP2C19, and CYP2D6.[159] 6β-Hydroxylation and to a lesser extent 16β-hydroxylation are the major transformations.[159] The 6β-hydroxylation of testosterone is catalyzed mainly by CYP3A4 and to a lesser extent CYP3A5 and is responsible for 75 to 80% of cytochrome P450-mediated testosterone metabolism.[159] In addition to 6β- and 16β-hydroxytestosterone, 1β-, 2α/β-, 11β-, and 15β-hydroxytestosterone are also formed as minor metabolites.[159][160] Certain cytochrome P450 enzymes such as CYP2C9 and CYP2C19 can also oxidize testosterone at the C17 position to form androstenedione.[159]
You may be interested in boosting your testosterone levels if your doctor says you have low levels, or hypogonadism, or need testosterone replacement therapy for other conditions. If you have normal testosterone levels, increasing your testosterone levels may not give any additional benefits. The increased benefits mentioned below have only been researched in people with low testosterone levels.

Why do we need magnesium? Magnesium is an essential nutrient in the body that can help decrease the risk of developing osteoporosis, improve insulin sensitivity, and lower the risk of hypertension. This article looks at other health benefits of magnesium, what happens if a person has a deficiency, supplements, and how to include it in the diet. Read now
AC, I just ran across the thread… definitely start the injections. Should help with levels that low. I’m 36 and have battled low T for 6-7 years. My labs came back to show 90ng/dl when I just turned 30, and I’ve done Testosterone cypionate injections @ 100mg/mL weekly, Testim, Androgel, and Fortesta over the years. I’m actually going to my endocrinologist tomorrow to have new blood work done.
Testosterone [Figure 1] is the main male sex hormone. It is responsible for male sexuality and is the main hormone-producing the features associated with masculinity such as substantial muscle mass, facial hair, libido, and sperm production.[1] Besides, the hormone has other vital functions as the basic chemical composition of testosterone is steroidal; and steroids are known to have significant physiological, as well as psychological, effects in male individuals, especially adults.[1] Testosterone production is reduced gradually in men starting from the age of 30.[2] Hence, testosterone blood concentrations slowly diminish as age progresses. As a result, men may experience a number of physiological and psychological events, such as a lack of sex-drive, erectile dysfunction, acute depression, fatigue, low energy levels, and insomnia.[3]
On the average, you need to sleep at least 8 hours per night to stay healthy. If you want a night sleep to contribute to the maximum testosterone production, it’s important to make your sleep comfortable. Thus, the bedroom temperature shouldn’t exceed 21°C. In addition, you should ventilate your bedroom thoroughly before sleeping. Furthermore, before going to bed, don’t overload your stomach with fatty foods, as well as don’t drink alcohol and caffeinated beverages. Finally, you have to avoid intense physical activity before bedtime.6
As mentioned earlier, too much protein can negate testosterone production quite a bit. If your protein intake is over 0.85g/lb of body weight a day, then you may not be making full use of each of the nutrients. Consuming these high amounts of protein can cause your cortisol and SHBG levels to increase, which in turn lowers testosterone production. What do you get out of this deal? Increased fat gain and lower testosterone levels.
In accordance with sperm competition theory, testosterone levels are shown to increase as a response to previously neutral stimuli when conditioned to become sexual in male rats.[40] This reaction engages penile reflexes (such as erection and ejaculation) that aid in sperm competition when more than one male is present in mating encounters, allowing for more production of successful sperm and a higher chance of reproduction.
Anabolic–androgenic steroids (AASs) are synthetic derivatives of testosterone that are commonly used among athletes aged 18–40 years, but many reports have demonstrated the presence of numerous toxic and hormonal effects as a result of long-term use of an AAS.[9] Testosterone-foods act as natural libido boosters. Due to the growing interest in herbal ingredients and other dietary supplements worldwide, the use of testosterone boosters is becoming more and more mainstream among athletes, but several side effects were documented. Hence, this study established to help in the assessment of the side effects and health risks which could occur among athletes consuming testosterone boosters.
NHT works to reach a targeted level of hormones in your body, restoring your body’s natural ability to keep healthy and fit. Hormones are beneficial at any age, but most commonly we administer the therapy to people in their 40’s, when your body naturally begins to slow production of certain hormones. Supplementing these declining hormones can keep your body fit and active for much longer. Bio-identical hormones are made from plants and are identical to the hormones naturally produced by your own body. We never use synthetic hormones, which have been shown to increase your risk of heart disease and diabetes.
In non-human primates, it may be that testosterone in puberty stimulates sexual arousal, which allows the primate to increasingly seek out sexual experiences with females and thus creates a sexual preference for females.[39] Some research has also indicated that if testosterone is eliminated in an adult male human or other adult male primate's system, its sexual motivation decreases, but there is no corresponding decrease in ability to engage in sexual activity (mounting, ejaculating, etc.).[39]
Saw palmetto and testosterone facts Testosterone is the primary male sex hormone. Boosting its levels can have many effects, such as promoting muscle growth and improving libido. Saw palmetto, a plant resembling the leaves of a palm tree, may boost testosterone levels and offer other health benefits. Learn more about saw palmetto and testosterone here. Read now
However, if you have normal testosterone levels and are looking for a boost, for strength gaining purposes, then D-Aspartic acid use may prove less fruitful. A study published in Nutrition Research showed that when the booster was given to men who resistance trained four times a week, their body composition and muscle strength was no different to men who took part in resistance training without the aid of D-Aspartic acid.
“She” being the key word. I had to quit a female doc because even though my level was down to 200, she thought I just needed more vitamin D! When I tried that and came back a few weeks later and told her there was no change in how I felt she refused to order another blood test, and after that wouldn’t even see me. I would never trust a female doctor with testosterone replacement therapy, as they all seem to have the same shit attitude from what my friends have told me, they treat it like it’s not a real thing even though you better bow down and kiss their asses when it comes to breast cancer and menopause.
“About 2 weeks after starting Andro400, I noticed my belly fat disappearing. Now, after only one month, I've lost about ten pounds all in my mid section. What a miracle! I have more energy and don't have to hold my gut in any longer. I'm more relaxed and my libido has increased 5 fold! I'm 58 years old and beginning to feel like a teenager again! Your product has delivered exactly as advertised. I'm elated!”

Feeling low energy, lack of enthusiasm, but not so much on the sexual side, seems okay. At age 63 started an exercise program. nothing seem to help bring me back, so had my blood test at age 64. 150. 6 months later 165. My doctor started me on testosterone patches after a heart and prostate exam. Now two months into program, now using the gel, there seems little change. Disappointed. I am guess my next blood test will show less than 200. I am disappointed sufficiently to decide not to continue the program. I mean, the drugs cost $500 a month, although my cost is less. I guess my question is if I quit the program, will my body return to its normal, or will it be worse. i can live with a low normal, but less would not not be acceptable.
Both Beast Sports’ Super Test and iSatori’s ISA-Test contain a proprietary blend, which means they don’t disclose the amount of each and every ingredient in the mix. This is only a problem if there is an ingredient tucked into a proprietary blend for which we need to know an amount, like magnesium and zinc. While none of the ingredients in Beast Sports’s proprietary blend raised any red flags, iSatori’s blend contains melatonin, a hormone that helps regulate sleep. Melatonin is an ingredient that has a hard upper limit — Healthline suggests at most 10mg for an adult — and even lower doses can interact poorly with many medications. Since we can’t confirm whether the amount of melatonin in iSatori’s proprietary blend is under 10mg, we cut iSatori.
I was age 55 with T level at150 so the va doctor started me out on bi weekly 200mg injections.Needless to say it really made me fell young again.

While steroids like DHEA can be used to boost testosterone, if used in the wrong dosages or by people who don’t need them they can raise T-levels far beyond the normal range, which is what causes accelerated muscle gain. According to Dr. Emil Hodzovic, who is a competitive bodybuilder as well as a doctor with Medichecks, steroids come with “a set of risks, including liver damage, hormone imbalance, high blood pressure, and a higher risk of a stroke or heart attack”.
Have you ever wondered why? When we are under stress, our body produces cortisol that is bad for our testosterone levels. This particular component blocks the production of testosterone. In addition, if there is a lack of Z’s then this is the bad news for your testosterone. You should know that the huge amounts of testosterone are produced during our sleep. Every guy knows that the “morning wood” comes only after a good night sleep.
My biggest symptom was fatigue. Interestingly, I had and have no problem with erections at all. Granted, I wasn’t getting spontaneous erections like when I was a teenager and into my late 20’s, but that was a good thing as getting an erection whenever and having no way to relieve it can get annoying. Anyway, my biggest concern with low T was/is energy levels and loss of muscle mass.

You should also know that a lot of people are deficient in Vitamin D. In the USA & many other western regions in the world, vitamin D deficiency is at epidemic proportions. The best way to increase your D levels is sun exposure. You only need 20-30 minutes of exposure to a large amount of skin (i.e., take your shirt off and go for a walk during the day).


Hello everyone. First off, thank you Dr. Abraham Morgentaler, for the excellent and refreshing article. I do not intend to spill my guts about symptoms or values on here as it has already been done so many times over. I will say that I am an RN BSN and have been on HRT for going on 6 yrs. I live in Oklahoma and when I first started noticing symptoms I knew something was wrong and began to do research myself. With an initial level of 241 no doctor here at that time, would even consider HRT as I was only 35ish at the time.
Since then, multiple studies have found no link between high testosterone levels and increasing your chances of developing prostate cancer. However — and this is a BIG however — if you already have prostate cancer, increased levels of testosterone may exacerbate the problem. It’s best to wait until after you treat your prostate cancer before you begin any T-boosting regimens. Tread carefully and talk with your doctor.
If a man's testosterone looks below the normal range, there is a good chance he could end up on hormone supplements—often indefinitely. "There is a bit of a testosterone trap," Dr. Pallais says. "Men get started on testosterone replacement and they feel better, but then it's hard to come off of it. On treatment, the body stops making testosterone. Men can often feel a big difference when they stop therapy because their body's testosterone production has not yet recovered."
