A large number of trials have demonstrated a positive effect of testosterone treatment on bone mineral density (Katznelson et al 1996; Behre et al 1997; Leifke et al 1998; Snyder et al 2000; Zacharin et al 2003; Wang, Cunningham et al 2004; Aminorroaya et al 2005; Benito et al 2005) and bone architecture (Benito et al 2005). These effects are often more impressive in longer trials, which have shown that adequate replacement will lead to near normal bone density but that the full effects may take two years or more (Snyder et al 2000; Wang, Cunningham et al 2004; Aminorroaya et al 2005). Three randomized placebo-controlled trials of testosterone treatment in aging males have been conducted (Snyder et al 1999; Kenny et al 2001; Amory et al 2004). One of these studies concerned men with a mean age of 71 years with two serum testosterone levels less than 12.1nmol/l. After 36 months of intramuscular testosterone treatment or placebo, there were significant increases in vertebral and hip bone mineral density. In this study, there was also a significant decrease in the bone resorption marker urinary deoxypyridinoline with testosterone treatment (Amory et al 2004). The second study contained men with low bioavailable testosterone levels and an average age of 76 years. Testosterone treatment in the form of transdermal patches was given for 1 year. During this trial there was a significant preservation of hip bone mineral density with testosterone treatment but testosterone had no effect on bone mineral density at other sites including the vertebrae. There were no significant alterations in bone turnover markers during testosterone treatment (Kenny et al 2001). The remaining study contained men of average age 73 years. Men were eligible for the study if their serum total testosterone levels were less than 16.5 nmol/L, meaning that the study contained men who would usually be considered eugonadal. The beneficial effects of testosterone on bone density were confined to the men who had lower serum testosterone levels at baseline and were seen only in the vertebrae. There were no significant changes in bone turnover markers. Testosterone in the trial was given via scrotal patches for a 36 month duration (Snyder et al 1999). A recent meta-analysis of the effects on bone density of testosterone treatment in men included data from these studies and two other randomized controlled trials. The findings were that testosterone produces a significant increase of 2.7% in the bone mineral density at the lumber spine but no overall change at the hip (Isidori et al 2005). These results from randomized controlled trials in aging men show much smaller benefits of testosterone treatment on bone density than have been seen in other trials. This could be due to the trials including patients who are not hypogonadal and being too short to allow for the maximal effects of testosterone. The meta-analysis also assessed the data concerning changes of bone formation and resorption markers during testosterone treatment. There was a significant decrease in bone resorption markers but no change in markers of bone formation suggesting that reduction of bone resorption may be the primary mode of action of testosterone in improving bone density (Isidori et al 2005).

A notable study out of Wayne State University in Indiana found that older men who had a mild zinc deficiency significantly increased their testosterone from 8.3 to 16.0 nmol/L—a 93 percent increase—following six months of zinc supplementation. Researchers of the study concluded that zinc may play an important role in modulating serum testosterone levels in normal healthy men.6
The amount of testosterone synthesized is regulated by the hypothalamic–pituitary–testicular axis (see figure to the right). When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. These latter two hormones stimulate the testis to synthesize testosterone. Finally, increasing levels of testosterone through a negative feedback loop act on the hypothalamus and pituitary to inhibit the release of GnRH and FSH/LH, respectively.
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.
Andy – If you take testosterone, your hypothalamus will notice an abundance of testosterone in your system and will instruct your pituitary gland not to send LH and FSH to your testicles. If you’re testicles are not receiving these two hormones, they will stop making testosterone. If you quit testosterone call turkey, you will likely fall back to your baseline level fairly quickly. There is a protocol however to get back to your normal production much quicker should you choose to quit therapy.
“However, the parallels don’t necessarily follow logically, creating a real need to bring more evidence to this area so that physicians and patients would be able to make more informed decisions based on the best possible evidence,” said Dr. Gill, a professor of medicine and the lead investigator at the Yale study site, the largest site participating in the TTrials, and coauthor of all 4 TTrials.
“Life for the winner is more glorious. It enters the next round of competition with already elevated testosterone levels, and this androgenic priming gives it an edge that increases its chances of winning yet again. Through this process an animal can be drawn into a positive-feedback loop, in which victory leads to raised testosterone levels which in turn leads to further victory.”
A side of garlic knots or onion bread can boost your sex drive … just make sure your date has a slice, too! Studies suggest a compound in the stinking rose triggers the release of luteinizing hormone, which regulates production of testosterone. One study showed supplementing with garlic as part of a high-protein diet could substantially boost testosterone levels. And a recent animal study found just 1 gram of onion per kg of body weight could boost T-levels by over 300 percent in just 20 days. Garlic and onions both contain the chemical diallyl disulfide, which stimulates the release of a hormone that spurs the production of testosterone.
I started testosterone therapy on August 25th 2005. I remember this so well because my life pretty much changed after that. I think I’ve had low testosterone my entire life, though I’ve always had a healthy sex drive I was always tired and always sensed something was wrong although I sought out treatment at the doctor’s but just could never quite pinpoint what the problem was. long story short, I’ve had nothing but good things from testosterone therapy. mostly just more vitality and a better outlook on life
55+ million men in america between 40 and 70 years of age is a large enough group to warrant interest in a thorough study of the aged male delivery system and other sex related issues. There is a good chance there are 55 million women out there wishing for some kind of help also. Those are significant numbers, about 1/3 of the total population and the lions share of the income producers. And the best the medical community can do is speculate at the real cause for a significant cancer? Perhaps prostate cancer is the real cause of global warming, there is no real science unless there is a real paycheck?
Fenugreek is an enigma, deep-fried in a mystery, and wrapped in secrecy. It can actually LOWER your testosterone levels while simultaneously increasing your libido and athletic performance, 2 effects that correlate with elevated testosterone levels. Strange. This is the first supplement I have come across that might have the opposite of the desired effect, and yet be worth taking anyway.
Testosterone may improve cognitive ability. Not only have studies shown that there is a link between testosterone levels and Alzheimer’s, they’ve also shown a link between T levels and overall cognitive ability, particularly in older men. One such study performed by Dutch researchers found a direct linear relationship between T levels and cognitive function, while other studies have found a linear relationship between memory loss and T levels. Because of these correlations, many researchers believe testosterone plays a role in preventing brain tissue decay in elderly men. The hormone’s connection to cognition explains why some of the symptoms of low T in men are memory loss, trouble concentrating, and “fogginess.”
Leafy green vegetables such as spinach are rich sources of folic acid. Low levels of folate can give rise to distorted sperm shapes such as ones with two heads or two tails. The sperm are also at an increased risk of chromosomal abnormalities. This means that firstly your sperm will find it difficult to reach an egg and even if it does reach an egg, it will not be able to fertilize it. Furthermore, even if these sperms are able to fertilize an egg, the chances of birth defects are quite high in such cases.

Testosterone. During adolescence and early adulthood, testosterone levels in men are naturally high resulting in a feeling of strength, sexual charge and vitality. But as men get older, the aging process causes testosterone levels to decline, often resulting in a decrease in sexual desire, decrease in muscle mass, excessive weight gain, feeling tired all day, extreme mood swings, insomnia, depression and hair loss.
This product is to be taken once daily on an empty stomach. Is there a particular time frame when food can be eaten? If I were to take this in the morning right when I wake up and then eat breakfast an hour later, is that fine? Also, mostly the only time of day my stomach is usually empty is right before going to bed. If it is taken at this time, will this affect sleep at all?
The partial synthesis in the 1930s of abundant, potent testosterone esters permitted the characterization of the hormone's effects, so that Kochakian and Murlin (1936) were able to show that testosterone raised nitrogen retention (a mechanism central to anabolism) in the dog, after which Allan Kenyon's group was able to demonstrate both anabolic and androgenic effects of testosterone propionate in eunuchoidal men, boys, and women. The period of the early 1930s to the 1950s has been called "The Golden Age of Steroid Chemistry", and work during this period progressed quickly. Research in this golden age proved that this newly synthesized compound—testosterone—or rather family of compounds (for many derivatives were developed from 1940 to 1960), was a potent multiplier of muscle, strength, and well-being.
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. 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.).
“I'm having great results. Everybody is seeing a difference. People say, “You look good! Did you lose weight? What are you taking?” I'm 59, and I'm bringing my belt down a couple different notches. I couldn't break 180 lbs for nothing, no matter what I tried. Now it's 175 lbs. and she's going from there. I was just doing it for the belly -- no matter what I just couldn't get rid of the belly (until now). And I'm not as tired as I used to be.“
An added testosterone benefit of my high fat and balanced protein and carb diet was that it probably helped me lose some body fat (I went from 18% to 12% body fat). Studies show that high fat diets actually contribute to increased body fat loss. And as we discussed earlier, as you lose body fat, your T production ramps up. Virtuous cycle for the win!
Oral ginger was reported to accelerate gastric emptying and stimulate gastric motility (spontaneous movements of the stomach that aid in digestion). Most studies report some beneficial effect on gastric emptying time but mostly during some sort of disease state [10,11]. In healthy individuals ginger also seems to increase gastric emptying via antral contraction stimulation . However, Phillips and colleagues  reported that ginger is not associated with an effect on gastric emptying. In animals, ginger and its active constituent -Gingerol were reported to enhance gastrointestinal tract transit .
Made many mistakes growing up. Late highschool, small group of guys tried Testosterone and obviously it worked great on all levels especially on the football field etc. College years we did it again and again but not anywhere near the levels of body builders we knew and saw at the gym. When it became harder to find, then….. poof it became “legal” in the form of Pro-hormones. Great right? Not so. It worked but it also worked on everything else in a negative way. Mainly liver toxicity that I noticed and just the general idea of not really knowing what was in it. When I was 38 I had a bad event with diverticulitis. I was hospitalized for 4 days and it was horrible. This is in an infection in a diverticula that forms in your intestines. It was so bad and fast that it spread with a rapid onset of epididymitis ( infection on the epididymis of your testical). After the hospital I went see my gastro who was a board member of a large anti aging group of doctors. We did bloodwork and My testosterone levels were lower than a woman! Like 110. He also explained to me that I had probably never fully recovered normal test levels from my last “get in shape” run with pro hormones 2 years before and it probably played a part in the weakening of my intestinal wall and immune system and after discussion I realized that I had exhibited all of the text book effects of low T to the letter. After spilling my guts to my doctor we decided upon the gel. It worked great but having kids around I was worried about it affecting them so we switched to in ejections taken every 2 weeks of cypionate 200mg and my wife helps me with that at home and I never stray from the regime . My levels are around 700 to 750 and basically PSA that is non existent. I am now 41 and feel great , go to Doctor twice a year for bloodwork and all is well. My doctor also tells me that in his opinion our environmental factors play a huge role in this, meaning hormones in meats, milks, public water etc. and because of that together with “Poor decision making (me in highschool, college etc) America is in the midst of an epidemic that is being under advertised and overlooked. I constantly read up on the latest info I can find and I liked reading this and your posts. Sometimes I feel guilty because I get comments on how I look and my energy levels and I wonder is this too good to be true? But if I am following a strict regiment and bloodwork reports good things…. Do I need to worry about anything else??? This is my story and I have never shared it with ANYONE other than my wife. Big move for me!! Last point……. This is a generalization but…….all women take hormones. It’s is universally accepted and part of a woman’s life without a doubt. Why is it Taboo to publicly discuss men and hormones? I guarantee if you are a man 35 and above and you did dumb things like me and or exhibit symptoms of low T, do yourself a huge favor and go see a doctor and get blood work done. More than likely you have it! I still hide all of this and I don’t want to shout it out because I feel embarrassed. WHY? Enough already!!!!
It seems that adequate testosterone levels are an important influence on sexual symptoms in the aging male and also influence the response of men to PDE-5 inhibitors, the first line treatment for erectile dysfunction in men. Many would now suggest screening for testosterone deficiency in all men presenting with erectile dysfunction (Gore and Rajfer 2004; Shabsigh 2005). This would seem appropriate because, in addition to benefits on sexual function, identification and treatment of hypogonadal men with testosterone could improve other symptoms of hypogonadism and protect against other conditions such as osteoporosis.
Most studies support a link between adult criminality and testosterone, although the relationship is modest if examined separately for each sex. Nearly all studies of juvenile delinquency and testosterone are not significant. Most studies have also found testosterone to be associated with behaviors or personality traits linked with criminality such as antisocial behavior and alcoholism. Many studies have also been done on the relationship between more general aggressive behavior/feelings and testosterone. About half the studies have found a relationship and about half no relationship. However, later it was found out that testosterone activates dominant, aggressive behavior if at the same time a person has high testosterone and low levels of cortisol in the blood. Conversely, a high level of testosterone and high levels of cortisol do not stimulate dominant behavior. Because cortisol inhibits the action of testosterone. This is probably why the results of the experiments were inconsistent.
“Poor lifestyle can mimic the symptoms of low testosterone and can actually cause low testosterone as well,” says Hodzovic. “The main culprits include lack of sleep, excessive stress, too little or too much exercise and too little or too much body fat. Getting healthy and active and eating a balanced nutritious diet along with enough sleep are the most important things to do.
Testosterone increases dominance and the desire for power. The link between testosterone and dominance has been demonstrated in numerous studies. T motivates men to gain and maintain social status. The desire for dominance can be a bad thing if it leads to criminal behavior, but it’s also what fuels the climb for success, motivates men to resist oppression and buck authority, and may even help you with the ladies…
One study looking at alcohol consumption found that increasing alcohol consumption led to a higher level of free & total testosterone compared to a non-drinking control group (20). Drinking did however lower SHBG testosterone levels, though this type of testosterone is bound to a protein meaning our bodies cannot use it to build muscle or increase our mood.
Millions of men use testosterone therapy to restore low levels and feel more alert, energetic, mentally sharp, and sexually functional. But it's not that simple. A man's general health also affects his testosterone levels. For instance, being overweight, having diabetes or thyroid problems, and taking certain medications, such as glucocorticoids and other steroids, can affect levels. Therefore, simply having low levels does not always call for taking extra testosterone.
Elevated testosterone levels have been demonstrated to increase the growth of body muscles and contribute to better activation of the nervous system, resulting in more power and strength, a better mood, enhanced libido, and many other benefits. Previous researches done on the anabolic role of testosterone and its impact on muscular strength in training-induced adaptations has provided rather conflicting findings, and a positive correlation between testosterone-mediated responses and both functional performance and body composition was found.[4,5] There are a number of naturally occurring substances that can boost testosterone levels in the body. Foods containing such substances are known as testosterone-foods; and they tend to be rich in vitamins, antioxidants, and minerals like zinc, which plays a key role in testosterone production.[2,6-8]
I am still on T therapy. But here’s what pisses me off: No one tells you that you will be hooked on the drug virtually forever! Don’t ever stop it abruptly! I did and I had a major crash: physically and emotionally. I went into the darkest depression ever…and I was lacking in energy so much that I had to have 4 naps a day…just to get through the day. I was also robbed of any initiative to do anything.

To get your levels into the healthy range, sun exposure is the BEST way to optimize your vitamin D levels; exposing a large amount of your skin until it turns the lightest shade of pink, as near to solar noon as possible, is typically necessary to achieve adequate vitamin D production. If sun exposure is not an option, a safe tanning bed (with electronic ballasts rather than magnetic ballasts, to avoid unnecessary exposure to EMF fields) can be used.
One study showed that six months of zinc supplementation among slightly zinc-deficient elderly men doubled serum levels of testosterone. And another eight-week trial found that college football players who took a nightly zinc supplement showed increased T-levels and increased leg strength that was 250 percent greater than a placebo! Holy quads, Batman! Research has also shown deficiencies in zinc to be a risk factor for infertility caused by low testosterone levels.
Bottom line: testosterone boosters aren’t right for a lot of people. We dive deep into ingredient research below, but typically, testosterone boosters contain at least one (and often three or more) different ingredients that each impact your circulatory system — both the heart and blood. If you’re taking any kind of blood-thinner medication, or you have a history of heart disease, these supplements can get really dangerous, really quickly. The simple fact of the matter is that hormones are tricky things to mess with, and a doctor should be your first port of call to help you safely achieve your goals — whether they’re related to fitness, weight, or libido.
Testosterone is the primary male sex hormone and an anabolic steroid. In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone is involved in health and well-being, and the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss.
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.

This is because your body is really good at self-regulating your hormone levels. So if you have normal testosterone levels, boosting above your natural base level may at best give you a few hours while your body makes, and then immediately processes out, the excess testosterone. This means you might experience higher than your average testosterone levels, but not by much, and only for a little while.
Proprietary blends are a growing problem in the supplement industry. This is where mix many ingredients together and list it on the label as a blend. The problem with this is you have no idea how much of each of those ingredients you are getting. Complete transparency is best so the customer knows what they are getting and it also helps limit side-effects.
Meat. Meat, particularly beef, provides our bodies with the protein it needs to create muscle (more muscle = more T) and the fats and cholesterol to make testosterone. My meat topping of choice was sliced up chuck steak. I grilled two of them on Monday and it lasted me until the next Monday. Every now and then I’d slow-cook some ribs or brisket to use as my meat topping. My philosophy was the fattier, the better.
A man with shrinking levels of testosterone actually may lose some body hair. Testosterone replacement therapy comes with a few potential side effects, including acne and breast enlargement. Testosterone patches may cause minor skin irritation. Topical gels may be easier to use, but great care must be taken to avoid transferring testosterone to someone else though skin-to-skin contact.
Another benefit of the increased muscle mass was that I got stronger. My bench press, squat, and deadlift all enjoyed significant gains during my experiment. It’s great to be able to bench press 225 pounds again for 5 sets of 5 like I used to in high school, and I’m on track to beat my maxes on the bench and squat that my 18-year-old self set over 12 years ago.
The other interesting thing about the study: men’s testosterone levels were lowest in March (at the end of winter) and highest in August (at the end of summer). Sunlight affects your vitamin D production, so you have seasonal dips and peaks. Get a blood test to check your levels, and if you’re low, take a high-quality vitamin D3 supplement. If you’re going to take D3, take vitamin K2 and vitamin A with it. The three work in sync, so you want them all to be balanced. Here are my dosage recommendations.
High levels of testosterone in the bloodstream lead to increased energy and aggressiveness. The latter pertains to one’s sense of motivation to train harder to achieve optimum muscle growth. Increased aggressiveness or motivation during a workout due to the intake of testosterone boosters guarantees faster progress to beginners as well as professional athletes and bodybuilders.
The sex hormone testosterone is far more than just the stuff of the alpha male's swagger. Though it plays a more significant role in the life of the biological male, it is actually present in both sexes to some degree. Despite popular perceptions that testosterone primarily controls aggression and sex drive—although it does play a role in both of those things—research has shown that individual levels of testosterone are also correlated with our language skills and cognitive abilities. Testosterone occurs in the body naturally, but can be administered as a medication, too: its most common uses are in the treatment of hypogonadism and breast cancer, as well as in hormone therapy for transgender men.
“Before taking Andro400, my husband weighed 290 lbs. He's a diabetic and his blood pressure was through the roof. I purchased Andro based on the reviews, and he's lost 60 - 70 lbs! It's enhanced him health-wise in a lot of aspects too. He used to be depressed because of his weight. The fact that he was losing weight like crazy gave him a lot of relief. He's not depressed now, he's really happy. He's more loving. And it's so exciting for me as a wife to see him happier -- it made me happier! So I'm really grateful. Andro400 gave him a lot of energy too because of the testosterone boost. The 3 main things everybody's noticing are: no more depression, a lot more energy and the huge weight loss. He went from size 42 to 38, so it's like, oh my God it's WORKING!! Trust me, we've tried a lot of other things that didn't work. And that's why I'm so excited because it's actually, literally changing our lives!”
Two of the immediate metabolites of testosterone, 5α-DHT and estradiol, are biologically important and can be formed both in the liver and in extrahepatic tissues. Approximately 5 to 7% of testosterone is converted by 5α-reductase into 5α-DHT, with circulating levels of 5α-DHT about 10% of those of testosterone, and approximately 0.3% of testosterone is converted into estradiol by aromatase. 5α-Reductase is highly expressed in the male reproductive organs (including the prostate gland, seminal vesicles, and epididymides), skin, hair follicles, and brain and aromatase is highly expressed in adipose tissue, bone, and the brain. As much as 90% of testosterone is converted into 5α-DHT in so-called androgenic tissues with high 5α-reductase expression, and due to the several-fold greater potency of 5α-DHT as an AR agonist relative to testosterone, it has been estimated that the effects of testosterone are potentiated 2- to 3-fold in such tissues.
The basis for my thinking that T levels could be boosted by cold baths came from a post I wrote a few years ago on the benefits of cold showers. One benefit I found in my research was that they could increase testosterone levels. I mentioned a 1993 study done by the Thrombosis Research Institute in England that found increased T levels after taking a cold shower. Here’s the thing. I can’t find a link to the original source and I can’t find any other studies that support this claim! So without supporting research, I’m unsure of the effects of cold showers on testosterone.
BSN Evotest the next ranked testosterone booster and is a unique option in that it’s available in both capsule and powdered drink form. For those who dislike swallowing pills, this will be a better route to go. There are mixed reports on the taste quality of the product, however, this is an individual preference and should not be something that deters you from purchasing it. It mixes fairly well by most reports, so is something that you should be able to easily take with you to the gym for use during the workout session.
For people who are worried about low or high testosterone, a doctor may perform a blood test to measure the amount of the hormone in the patient's blood. When doctors find low-T, they may prescribe testosterone therapy, in which the patient takes an artificial version of the hormone. This is available in the following forms: a gel to be applied to the upper arms, shoulders or abdomen daily; a skin patch put on the body or scrotum twice a day; a solution applied to the armpit; injections every two or three weeks; a patch put on the gums twice a day; or implants that last four to six months.
Sergeant Steel is arguably the strongest testosterone booster on the market as it combines 16 effectively dosed ingredients that support testosterone increases and estrogen reduction. It’s not often that you come across a product that combines all of the top ingredients and provides you with their proper dosages. Users have been reporting strong increases in libido, strength, sense of well being, muscle hardness, and improved recovery. If you are looking for a no-holds barred test booster, look no further than Sergeant Steel.
12) Use Aswaghanda and Collagen Protein: This adaptogenic herb has been shown to reduce stress hormone, increase DHEA and boost testosterone levels. You can take the Cortisol Defense to help you get restorative sleep at night which will support your testosterone. In addition, I personally enjoy using the Organic Bone Broth Collagen in addition to the Amino Strong for a post weight training shake. This protein powder has all the benefits of collagen protein and it has 500 mg of high potency ashwagandha in each serving!

Testosterone booster products obtained from trusted sources and administered as per the recommendations of the manufacturer may still present some health risks. The present case provided weak evidence of causality between acute liver injury and a commercial testosterone booster. To guarantee an optimal outcome with no severe side effects, further research is warranted to confirm the present findings and determine whether the effects observed in this case report would be statistically significant in larger samples.
Low testosterone levels have a dramatic effect on emotional state. The American Academy of Family Physicians lists depression, impaired cognition and increased fatigue as symptoms of low testosterone production, or hypogonadism. Testosterone replacement therapy for hypogonadal men has successfully reduced negative moods relating to fatigue and depression while increasing feelings of self-esteem. Increasing testosterone in eugonadal men has also shown positive emotional benefits such as increased feelings of self-esteem and reduction of fatigue. The intensity of these benefits is dependent on dosage; a wide body of literature on testosterone increase has shown that at higher dosage aggression, and aggressive response, can become pronounced.
Some of them can benefit dieters or competitive athletes. These individuals often experience significant decreases in their testosterone levels as a result of the restrictive or stressful exercise or diet regimen. It is worth mentioning that many of them can actually benefit healthy and hyper-active individuals (for example, professional weight lifters), but we can’t know that for sure because there aren’t enough studies to back up this claim.
Think: when you were teenager: you were active without thinking of ways to be active. When you start TRT, you want to be mobile/active (maybe again), don’t forget this when you stop TRT. You have to think of ways to incorporate activity into your routine or you get porky.When you cycled, walked everywhere as a teen you did this automatically. Without the hormone stimulus you must use your head and memories of what to do. here’s where the memory issue occurs.
Cross-sectional studies have found a positive association between serum testosterone and some measures of cognitive ability in men (Barrett-Connor, Goodman-Gruen et al 1999; Yaffe et al 2002). Longitudinal studies have found that free testosterone levels correlate positively with future cognitive abilities and reduced rate of cognitive decline (Moffat et al 2002) and that, compared with controls, testosterone levels are reduced in men with Alzheimer’s disease at least 10 years prior to diagnosis (Moffat et al 2004). Studies of the effects of induced androgen deficiency in patients with prostate cancer have shown that profoundly lowering testosterone leads to worsening cognitive functions (Almeida et al 2004; Salminen et al 2004) and increased levels of serum amyloid (Gandy et al 2001; Almeida et al 2004), which is central to the pathogenesis of Alzheimer’s disease (Parihar and Hemnani 2004). Furthermore, testosterone reduces amyloid-induced hippocampal neurotoxity in vitro (Pike 2001) as well as exhibiting other neuroprotective effects (Pouliot et al 1996). The epidemiological and experimental data propose a potential role of testosterone in protecting cognitive function and preventing Alzheimer’s disease.
A: According to the NIH, normal values for testosterone levels in men can range from 300 to 1,200ng/dL. There can be many different causes of low testosterone including age, diseases, accidents, and medications. Symptoms of low testosterone may include: loss of sex drive, erectile dysfunction, depressed mood, and difficulty concentrating. Low testosterone levels may also bring around body changes including: hair loss, decrease in blood cells possibly leading to anemia, fragile bones, and a decrease in muscle mass. There are different testosterone replacement therapies including patches, such as Androderm; gels, such as Androgel and Testim; and injections, such as testosterone cypionate. Only your health care provider can decide if and what kind of testosterone replacement therapy is appropriate for you. Testosterone replacement therapy is not right for everyone. Patient with certain prostate issues or breast cancer should not take testosterone. For more specific information, consult with your doctor for guidance based on your health status and current medications, particularly before taking any action. Kristen Dore, PharmD

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.
DAA (D-Aspartic Acid): When it comes to potent ingredients, D-Aspartic Acid is probably one the most potent ones currently available for boosting testosterone levels. This ingredient is used by sportsmen and bodybuilders alike to boost performance and gains, while it has also been shown to aid infertile men. DAA works with the brain, which stimulates the release of the luteinizing hormone that produces testosterone and also the secretion of growth hormone. Testosterone Synthesis also increases along with the other effects.
Testosterone was first used as a clinical drug as early as 1937, but with little understanding of its mechanisms. The hormone is now widely prescribed to men whose bodies naturally produce low levels. But the levels at which testosterone deficiency become medically relevant still aren’t well understood. Normal testosterone production varies widely in men, so it’s difficult to know what levels have medical significance. The hormone’s mechanisms of action are also unclear.
