Testosterone is used as a medication for the treatment of males with too little or no natural testosterone production, certain forms of breast cancer,[10] and gender dysphoria in transgender men. This is known as hormone replacement therapy (HRT) or testosterone replacement therapy (TRT), which maintains serum testosterone levels in the normal range. Decline of testosterone production with age has led to interest in androgen replacement therapy.[109] It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful.[110]
Watch out for ingredients that interfere with blood clotting If you are taking any kind of blood medication, take aspirin or ibuprofen, or have any kind of blood-related condition, you’ll want to consult your doctor before taking any of these supplements. Fenugreek, Forskolin, and Acetyl-L-carnitine are just a few of the ingredients that can make these situations worse and increase your chances of bruising and bleeding.
With ingredients like Fenugreek, Ashwagandha, Shilajit, and Boron Citrate, you can expect to see some increases in lean muscle mass thanks to the hike in free and total testosterone levels as well as its ability to suppress cortisol, a natural hormone that can reduce the body’s ability to use fat stores as energy. True GRIT Test Booster does not contain proprietary blends, so you can actually see the exact dosage you are getting from each ingredient listed.

In fact, high cortisol deals a crushing blow to testosterone in two ways. During, long-lasting stress, high amounts of cortisol release very often and have a direct negative influence on T levels. Thus, cortisol inhibits testosterone synthesis in the testes and hypothalamus. In addition, the production of cortisol is impossible without cholesterol. But testosterone synthesis also demands cholesterol. Since during stress cholesterol is first of all used for making cortisol, T levels simply plummet.


I am now 65 & have had Low-T problems since I was about 60. I took topical Testosterone for a few years until insurance stopped covering it. Then I took injections at a Men's Health-Low-T Clinic. Then I was diagnosed with Prostate Cancer & was told to stop taking Testosterone. I underwent radiation treatment to cure the Prostate cancer, but since there is a theory that taking Testosterone can lead to Prostate cancer, I have chosen not to resume taking it. While I am glad to be free of the cancer, I have been feeling extremely fatigued & tired all the time to the point that doing much of anything like a little yard work would leave me exhausted for days.
Testosterone is included in the World Health Organization's list of essential medicines, which are the most important medications needed in a basic health system.[111] It is available as a generic medication.[10] The price depends on the form of testosterone used.[112] It can be administered as a cream or transdermal patch that is applied to the skin, by injection into a muscle, as a tablet that is placed in the cheek, or by ingestion.[10]
I am 31, been on HRT for about 6 months now. Started with Oxandralone (orally, 3 x 10mg tablets per day) and found a 20-30% increase in strength and outlook on life. Stopped taking it and now use Primo Testostin Depot (test enanthate – 1 x 250mg shot every 2 weeks). In the first week I feel a lot stronger, voice deepens etc but these benefits quickly diminish after about 5-7 days
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.
Inaccurate or misinterpreted test results can either falsely diagnose or miss a case of testosterone deficiency. Your testosterone level should be measured between 7 am and 10 am, when it's at its peak. Confirm a low reading with a second test on a different day. It may require multiple measurements and careful interpretation to establish bioavailable testosterone, or the amount of the hormone that is able to have effects on the body. Consider getting a second opinion from an endocrinologist.
Other stereotypical "macho" behaviors can affect testosterone in women, according to a 2015 report in the Proceedings of the National Academy of Sciences. For example, posing in a powerful way increases testosterone in both women and men. The 2015 report showed that having women role-play a position of power — acting like a boss — had the same effect.

One preliminary study by researchers from Tikrit University showed high statistically significant increase of serum hormones (p< 0.01) in infertile men [9]. After 30 week treatment serum testosterone has increased by 17,7%, serum luteinizing hormone by 43,2% and serum follicle-stimulating hormone by 17,6%; dosage of ginger used was not disclosed [9]. It is suggested that improved testosterone production is because ginger was shown to be effective in decreasing SDF (sperm DNA Fragmentation) in infertile men [22]. SDF is negatively correlated with testosterone levels [23].


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.
ZMA (unnecessary). So when I researched how to increase testosterone, a supplement called ZMA kept popping up. It’s a blend of zinc, magnesium, and vitamin B6. The purported benefits of ZMA include better and deeper sleep which indirectly is supposed to increase testosterone. Zinc and magnesium are necessary minerals in testosterone production, so a mega-dose should be useful, right? Well, no. I bought some and took it during the duration of experiment. I should have done some more research before I made the purchase. While one study in 1998 showed increased strength among athletes taking ZMA, two recent studies (study 1, study 2) have shown that it has absolutely no effect on total or free testosterone levels. Crap. My advice, unless you have a zinc and magnesium deficiency, no need to waste your money on this.

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).
This is over simplified but should offer you some clarity to what you are experiencing – If you are getting Testosterone Cypionate injections every 2 weeks, then you are on the roller coaster. I have great results with weekly injections and some folks need bi-weekly injections. It’s all how your body reacts but every 2 weeks is just plain too far apart as the product is relatively ineffective after 10 days. Measurable at 10 days? Somewhat but still ineffective at that point.
Lean beef, chicken, fish, and eggs are some of your options. Tofu, nuts, and seeds have protein, too. Try to get about 5 to 6 ounces per day, although the ideal amount for you depends on your age, sex, and how active you are. When you don't eat enough of these foods, your body makes more of a substance that binds with testosterone, leaving you with less T available to do its job.
That said, a group of researchers at the National University of Malaysia did a systemic literature review of longjack, looking for clinical research that demonstrated a relationship between the shrub and testosterone levels. Of 150 articles, only 11 met their inclusion criteria — involving humans and scientifically rigorous. However, of those 11 studies, seven “revealed remarkable association” between using longjack and improving male sexual health, while the remaining four “failed to demonstrate sufficient effects.” The team concluded that longjack looks “promising” when it comes to raising low testosterone, and that there is convincing evidence that it works.

   The International Journal of Sports Physiology and Performance recently studied tennis players, rugby teams, and wrestlers to find a link between testosterone and competitive outcome. They found that the difference between winning and losing was reflected in testosterone levels! The athletes' own natural testosterone prior to the game was directly related to the outcome after the game -- the higher the testosterone, the more frequently the athlete won.6
Testosterone may increase competitiveness. Men are known to be a competitive bunch and testosterone is likely responsible for our drive to win. Testosterone is linked with a man’s desire for power and status (Dabbs & Dabbs 2000). Testosterone ramps up before a fight or competition – producing effects on muscle mass and hemoglobin, quickening reactions, improving visual acuity, and increasing your feelings of endurance and indomitability. It also increases your “gameness:” One study showed that a man’s testosterone level after losing a game predicted whether or not he got back in for another round. Men who experienced a severe drop were less likely to play again, while men who experienced little or no drop in T levels got back into the game. Researchers concluded from this observation that T is one of the factors driving competitiveness in men.
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.
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.
Sprinting has been shown numerous times that it has positive effects on testosterone levels. One 2011 study (ref 84) looked at weightlifters who performed 4x35m sprints twice a week. In contrast to the control group (who continued lifting but did not sprint), it was found that “After the 4-week training program, total testosterone and the total testosterone/cortisol ratio increased significantly in the (sprinters) EXP group”.
For men with low blood testosterone levels, the benefits of hormone replacement therapy usually outweigh potential risks. However, for most other men it's a shared decision with your doctor. It offers men who feel lousy a chance to feel better, but that quick fix could distract attention from unknown long-term hazards. "I can't tell you for certain that this raises your personal risk of heart problems and prostate cancer, or that it doesn't," Dr. Pallais says.
Spinach/Spring Salad Mix. This was the base of my salad. I used Organic Girl Greens from Whole Foods. Yeah, I know. The base of my Man Salad came from a company called Organic Girl. Spinach and other leafy green vegetables contain minerals like magnesium and zinc, which have been shown to aid in testosterone production (study on magnesium, and another; study on zinc)
Some of the effects of testosterone treatment are well recognised and it seems clear that testosterone treatment for aging hypogonadal men can be expected to increase lean body mass, decrease visceral fat mass, increase bone mineral density and decrease total cholesterol. Beneficial effects have been seen in many trials on other parameters such as glycemic control in diabetes, erectile dysfunction, cardiovascular risk factors, angina, mood and cognition. These potentially important effects require confirmation in larger clinical trials. Indeed, it is apparent that longer duration randomized controlled trials of testosterone treatment in large numbers of men are needed to confirm the effects of testosterone on many aspects of aging male health including cardiovascular health, psychiatric health, prostate cancer and functional capacity. In the absence of such studies, it is necessary to balance risk and benefit on the best available data. At the present time the data supports the treatment of hypogonadal men with testosterone to normalize testosterone levels and improve symptoms. Most men with hypogonadism do not have a contraindication to treatment, but it is important to monitor for adverse consequences including prostate complications and polycythemia.
“I see people who've been doing things in the gym and they've never been told that it can shut off your own production and it can also irreversibly lower your sperm count,” says Roked. “These are all quite serious issues that even though they may be rare if it happened to you it would cause a big impact on your life, so I'd say it's always best to do things with a specialist, but also for anyone it's not a great idea to take things that aren't needed."

Testosterone is only one of many factors that influence aggression and the effects of previous experience and environmental stimuli have been found to correlate more strongly. A few studies indicate that the testosterone derivative estradiol (one form of estrogen) might play an important role in male aggression.[66][71][72][73] Studies have also found that testosterone facilitates aggression by modulating vasopressin receptors in the hypothalamus.[74]


However, testosterone is only one of many factors that aid in adequate erections. Research is inconclusive regarding the role of testosterone replacement in the treatment of erectile dysfunction. In a review of studies that looked at the benefit of testosterone in men with erection difficulties, showed no improvement with testosterone treatment. Many times, other health problems play a role in erectile difficulties. These can include:
Testosterone replacement therapy can successfully treat erectile dysfunction and loss of libido in men with low testosterone from either advancing age or hypogonadism. Although the effects of increased testosterone are more dramatic in hypogonadal men there are also benefits to the libido of men with normal gonadal, also called eugonadal, function. In a 2004 study published in the "Journal of Endocrinology and Metabolism," researchers found that increasing peak testosterone levels to between 400 and 500 percent above baseline in subjects resulted in a significant increase in sexual arousability over placebo subjects.
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.

This particular product contains the largest dose of D-Aspartic Acid making it a highly effective muscle and strength builder. In addition, TestoFuel contains optimum doses the proven ingredients of Vitamin D, Oyster Extract, Zinc, Magnesium, Vitamin B6, Vitamin K2, Fenugreek and Siberian Ginseng. And you won’t get filler ingredients with this one like you do with many others.


This is the best BCAA supplement ever created.  You see this is not your typical BCAA supplement that all the other supplement companies sell.  Those products are simply free-form amino acids made by some Chinese manufacturer and packaged in the United States.  Free form amino acid supplements have been around since the 1980’s and they have never been proven to be helpful in building muscle mass.  In fact after whey protein came out in the 90’s it really made BCAA amino acids obsolete because whey protein contains over 30% BCAA.  If you want more BCAA’s simply use another scoop of whey protein instead of BCAA powder.  Its cheaper, tastes better, and contains plenty of BCAA plus all the other amino acids.  Ok so now that I have convinced you that free form BCAA’s supplements are pretty much worthless let me tell you about our new Advanced BCAA’s.
Levels of testosterone naturally decrease with age, but exactly what level constitutes "low T," or hypogonadism, is controversial, Harvard Medical School said. Testosterone levels vary wildly, and can even differ depending on the time of day they're measured (levels tend to be lower in the evenings). The National Institutes of Health includes the following as possible symptoms of low testosterone:

In essence, there are two types of testosterone boosters, namely natural and synthetic supplements. Anabolic steroids which are under the synthetic category are known to deliver positive results as well as nasty side effects. It is due to this reason that an increasing number of bodybuilders and athletes are now utilizing safer testosterone boosters.
In addition to that, one positive benefit that this product offers that not all natural testosterone boosters do is that it can help to improve your overall mood state. While maintaining a better mood is clearly a favorable thing, it also helps out in terms of your muscle building results because the better your mood is, the higher your motivation tends to be, which then means more effort put forth in the gym.

Vitamin D3: Vitamin D3 is actually more hormone than it is a vitamin. Vitamin D is taken in by around 10% of our diets and D3 is mostly absorbed from the sun, which can be linked to greater testosterone production. The link between the two is a result from the luteinizing hormone playing its role. Read more about how vitamin D3 effects testosterone — the evidence is staggering.
A number of epidemiological studies have found that bone mineral density in the aging male population is positively associated with endogenous androgen levels (Murphy et al 1993; Ongphiphadhanakul et al 1995; Rucker et al 2004). Testosterone levels in young men have been shown to correlate with bone size, indicating a role in determination of peak bone mass and protection from future osteoporosis (Lorentzon et al 2005). Male hypogonadism has been shown to be a risk factor for hip fracture (Jackson et al 1992) and a recent study showed a high prevalence of hypogonadism in a group of male patients with average age 75 years presenting with minimal trauma fractures compared to stroke victims who acted as controls (Leifke et al 2005). Estrogen is a well known determinant of bone density in women and some investigators have found serum estrogen to be a strong determinant of male bone density (Khosla et al 1998; Khosla et al 2001). Serum estrogen was also found to correlate better than testosterone with peak bone mass (Khosla et al 2001) but this is in contradiction of a more recent study showing a negative correlation of estrogen with peak bone size (Lorentzon et al 2005). Men with aromatase deficiency (Carani et al 1997) or defunctioning estrogen receptor mutations (Smith et al 1994) have been found to have abnormally low bone density despite normal or high testosterone levels which further emphasizes the important influence of estrogen on male bone density.

Overall, few patients have a compelling contraindication to testosterone treatment. The majority of men with late onset hypogonadism can be safely treated with testosterone but all will require monitoring of prostate parameters HDL cholesterol, hematocrit and psychological state. It is also wise to monitor symptoms of sleep apnea. Other specific concerns may be raised by the mode of delivery such as local side effects from transdermal testosterone.
Tribulus terrestris is an ingredient commonly presented as improving testosterone levels, but has not been found to be more effective than a placebo or possess any testosterone increasing properties. WebMD cautions that it interferes with Lithium and diabetes medications, and in general, not enough is known about tribulus terrestris to recommend a dosage for anyone.
Testosterone plays a role in certain behaviors, including aggression and dominance. It also helps to spark competitiveness and boost self-esteem. Just as sexual activity can affect testosterone levels, taking part in competitive activities can cause a man’s testosterone levels to rise or fall. Low testosterone may result in a loss of confidence and lack of motivation. It can also lower a man’s ability to concentrate or cause feelings of sadness. Low testosterone can cause sleep disturbances and lack of energy.
Some foods, vitamins, and herbs can help boost your testosterone levels. Be sure to talk to your doctor, if you’re concerned about low testosterone. These alternative and natural treatments aren’t proven to be more, or as, effective as traditional testosterone therapy. Some may also interact with any medications you may be taking and cause unintended side effects.
This is one of the most controversial recommendations I make, but it shouldn’t be. It’s no different than using thyroid medication. If your levels are low, and the other techniques here don’t work, use TRT. You will like your life again. If your levels are low, bioidentical testosterone will make you live longer and better, provided you use it right.
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.
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.

In addition, the gel forms of testosterone, applied under your arm or on your upper arm and shoulder, can be transferred to others if you don’t wash the area after applying it. Children exposed to the hormone have experienced enlargement of the penis or clitoris, growth of pubic hair, increased libido, and aggressive behavior. Women can experience acne and the growth of body hair and, if they are pregnant or breastfeeding, can transfer the hormone to their babies.


Likewise, the amino acids in a protein-rich diet play a big role in both testosterone and muscle growth. As Chris Lockwood, Ph.D., explains, "When combined with training, which increases the sensitivity of androgen receptors, and the consumption of essential amino acids necessary to support protein synthesis, the effects of testosterone on muscle and performance is significantly amplified."[3,4]
A number of research groups have tried to further define the relationship of testosterone and body composition by artificial alteration of testosterone levels in eugonadal populations. Induction of a hypogonadal state in healthy men (Mauras et al 1998) or men with prostate cancer (Smith et al 2001) using a gonadotrophin-releasing-hormone (GnRH) analogue was shown to produce increases in fat mass and decreased fat free mass. Another experimental approach in healthy men featured suppression of endogenous testosterone production with a GnRH analogue, followed by treatment with different doses of weekly intramuscular testosterone esters for 20 weeks. Initially the experiments involved men aged 18–35 years (Bhasin et al 2001) but subsequently the study was repeated with a similar protocol in men aged 60–75 years (Bhasin et al 2005). The different doses given were shown to produce a range of serum concentrations from subphysiological to supraphysiological (Bhasin et al 2001). A given testosterone dose produced higher serum concentrations of testosterone in the older age group (Bhasin et al 2005). Subphysiological dosing of testosterone produced a gain in fat mass and loss of fat free mass during the study. There were sequential decreases in fat mass and increases in fat free mass with each increase of testosterone dose. These changes in body composition were seen in physiological and supraphysiological treatment doses. The trend was similar in younger versus older men but the gain of fat mass at the lowest testosterone dose was less prominent in older patients (Bhasin et al 2001; Bhasin et al 2005). With regard to muscle function, the investigators showed dose dependent increases in leg strength and power with testosterone treatment in young and older men but there was no improvement in fatigability (Storer et al 2003; Bhasin et al 2005).

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.

Ben has mentioned APOE many times, as in this podcast, with the reference in this transcript as something like 34/44. I’ve always assumed that meant a number of different genes that related to APOE having the homozygous or heterzygous mutations. I’ve only been able to find one rs in my 23andme raw data that seems meaningful to this, rs429358. How do you all figure out your APOE status? Are you getting this from one of the other companies that analyzes part of your raw data for you?

Inaccurate or misinterpreted test results can either falsely diagnose or miss a case of testosterone deficiency. Your testosterone level should be measured between 7 am and 10 am, when it's at its peak. Confirm a low reading with a second test on a different day. It may require multiple measurements and careful interpretation to establish bioavailable testosterone, or the amount of the hormone that is able to have effects on the body.
