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.

Sugar is to testosterone what kryptonite is to Superman. Eliminating sugar is probably the single most powerful way to increase your performance, in part because sugar absolutely devastates your testosterone levels (but all carbs do not, especially under heavy training.) In one study of 74 men, a 75g dose of sugar – about the equivalent of a bottle of soda – decreased serum testosterone by 25% in under an hour, and levels stayed low for at least 2 hours [7]. On top of that, 15% of the men who started with normal testosterone dipped into the hypogonadal range after they ate sugar – that’s the range in which doctors diagnose men’s testes and women’s ovaries as failing. When you do eat carbs, stick to Bulletproof ones like sweet potatoes and squash. My recommendations for types of carbs and how often to eat them are here.
This study [9] also reported significantly increased glutathione levels. Glutathion has been shown to have a synergetic effect with l-citrulline as their combination further increases nitrate and nitrite levels and contributes to the sustained release of NO. While some previous studies have indicated that glutathione stimulates L-arginine turnover and increases nitric oxide synthase (NOS).
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.
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.
Exercise is the original testosterone booster, and it’s one of the most powerful full-body hacks around. Men see a sharp increase in both testosterone and human growth hormone (HGH) after lifting weights, and the boost is greater with shorter rest time between sets (1 minute rest outperforms 3 minutes rest) [9]. With the shorter rest time, women also get a large boost in HGH.

When we face stress, our adrenal glands secrete cortisol to prepare our bodies and minds to handle the stressful situation — the primal fight-or-flight response. In small dosages, cortisol is fine and even useful, but elevated cortisol levels for prolonged periods can do some serious damage to our bodies and minds. One area that seems to take a hit when cortisol is high is our testosterone levels. Several studies have shown a link between cortisol and testosterone. When cortisol levels are high, testosterone levels are low; and when testosterone levels are high, cortisol levels are low.


A testicular action was linked to circulating blood fractions – now understood to be a family of androgenic hormones – in the early work on castration and testicular transplantation in fowl by Arnold Adolph Berthold (1803–1861).[181] Research on the action of testosterone received a brief boost in 1889, when the Harvard professor Charles-Édouard Brown-Séquard (1817–1894), then in Paris, self-injected subcutaneously a "rejuvenating elixir" consisting of an extract of dog and guinea pig testicle. He reported in The Lancet that his vigor and feeling of well-being were markedly restored but the effects were transient,[182] and Brown-Séquard's hopes for the compound were dashed. Suffering the ridicule of his colleagues, he abandoned his work on the mechanisms and effects of androgens in human beings.
Japanese Knotweed (a.k.a Hu Zhang or Polygonum cuspidatum) is highlighted by WebMD as needing more evidence to rate its effectiveness in a number of different areas: like treating constipation and liver or heart disease. They also warn that it can interact poorly with medications that are changed and broken down by the liver, and those that slow blood clotting (anticoagulants and antiplatelets).
Testosterone is a key hormone as it relates to both sexual drive and muscle growth. Testosterone boosters are meant to increase testosterone levels in the blood. Now while most healthy men under the age of 65 may not need a testosterone boosting supplement, it is true that testosterone levels decrease as we get older. That could lead to a host of things from a loss in muscle mass to problems performing in the bedroom. There are natural testosterone booster, however, and you should consider those to minimize potential side effects.
Results from the clinical trial demonstrated that there were significant increases in hemoglobin in both men with unexplained anemia as well as men with anemia from known causes who used the testosterone gel. These results may be of clinical value, and testosterone treatment could be used to boost hemoglobin levels in men more than 65 who have unexplained anemia and low testosterone. However, more research needs to be done.
DHEA (dehydroepiandrosterone) extract - this is a chemical that used in your body which a ‘hormone precursor’. This means it’s the chemical used by the body to create hormones like oestrogen or testosterone. When taken as supplement it is believed to boost testosterone levels, but DHEA has not been shown to increase testosterone in men. DHEA comes in two form:

After various studies in animals had shown anabolic (muscle building) properties among the various Fenugreek benefits, a study was conducted on men undergoing resistance training. During the study the participants trained in a supervised manner 4 times a week for 8 weeks. Although the levels of DHT (Dihydrotestosterone) were reduced in those taking the Fenugreek supplement, other hormonal markers were not affected[4]. Another study further supported those findings, while also reporting that those taking the supplement witnessed an additional 2kg of fat loss and 2kg more muscle mass gain over the same period[5]. Impressive results indeed.
Testosterone is indisputably the king of hormones when it comes to the gym. While it’s responsible for reproductive development, it’s better known for its major role in promoting muscle growth, increasing bone density, and even how body fat is distributed. Testosterone levels are also a huge influencer in terms of overall health and emotional state. With age, however, natural testosterone production naturally declines, leading to higher levels of body fat and more difficulty building muscle, not to mention a decrease in libido.
Before assessing the evidence of testosterone’s action in the aging male it is important to note certain methodological considerations which are common to the interpretation of any clinical trial of testosterone replacement. Many interventional trials of the effects of testosterone on human health and disease have been conducted. There is considerable heterogenicity in terms of study design and these differences have a potential to significantly affect the results seen in various studies. Gonadal status at baseline and the testosterone level produced by testosterone treatment in the study are of particular importance because the effects of altering testosterone from subphysiological to physiological levels may be different from those of altering physiological levels to supraphysiological. Another important factor is the length of treatment. Randomised controlled trials of testosterone have ranged from one to thirty-six months in duration (Isidori et al 2005) although some uncontrolled studies have lasted up to 42 months. Many effects of testosterone are thought to fully develop in the first few months of treatment but effects on bone, for example, have been shown to continue over two years or more (Snyder et al 2000; Wang, Cunningham et al 2004).
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.”

if you’re a physician, you’re the real one who’s playing doctor. Stop prescribing low T treatment and let your patients go to a real doctor and not continue suffering. A simple picture of how hormones are created and their pathways will make you understand that E follows T, when we increase T, E2 will follow which negates all the positive effects of treatment. Without understanding this, you better leave the patient alone.

A: Androderm comes in the form of a transdermal patch and is used for testosterone replacement therapy in patients who have insufficient levels of testosterone. Testosterone is a hormone produced in the body that plays a key role in many physiological processes in men. In some men, however, the body does not produce enough of the hormone, resulting in a variety of symptoms including decreased libido, erectile dysfunction, muscle loss, anemia and depression, among others. Androderm helps treat these symptoms and raise low testosterone levels by delivering therapeutic amounts of the hormone, which are absorbed through the skin. According to the prescribing information for Androderm, depression was a reported side effect of the medication. Other common side effects of Androderm include itching and redness at the application site, prostate abnormalities, headache, and burning or hardening of the skin at the application site. Less common side effects of Androderm include reduced libido (sex drive), fatigue, high blood pressure, anxiety, confusion, increased appetite, and body pain. For more specific information, consult with your doctor for guidance based on your health status and current medications, particularly before taking any action. Your physician can determine if your dosage of the medication needs to be adjusted or if an alternative medication should be considered. Lori Poulin, PharmD
While testosterone stimulates a man’s sex drive, it also aids in achieving and maintaining an erection. Testosterone alone doesn’t cause an erection, but it stimulates receptors in the brain to produce nitric oxide. Nitric oxide is a molecule that helps trigger a series of chemical reactions necessary for an erection to occur. When testosterone levels are too low, a man may have difficulty achieving an erection prior to sex or having spontaneous erections (for example, during sleep).
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.”
Sitting for long stretches of time increases the odds of illness and untimely death. Here are some simple tricks to get yourself out of your chair: While you're on the phone, stand up and walk around. When watching TV, stand and pace during commercials. Instead of sitting at your makeup table, stand up. In general, try to get on your feet every 30 minutes.
This doesn’t mean Super Test is perfect — we take a closer look at some of its ingredients below — but it beats out the competition. Every other supplement we looked at either didn’t have all four ingredients, overdosed us on vitamins or minerals (a good way to develop kidney and liver problems), contained ingredients that would harm us, or some combination thereof.
Ok. So this product is meant to be taken continuously and without side-effects. But my question is, will there be replenishment from this product in aiding the body's natural ability to produce testosterone? In other words, will there ever be a time when I can say well I don't have to take this any more as my body is producing testosterone again on it's own and my muscle mass has been enhanced?
Results from the clinical trial demonstrated that there were significant increases in hemoglobin in both men with unexplained anemia as well as men with anemia from known causes who used the testosterone gel. These results may be of clinical value, and testosterone treatment could be used to boost hemoglobin levels in men more than 65 who have unexplained anemia and low testosterone. However, more research needs to be done.
Another point I’d like to make for people worried about a link between high testosterone and prostate cancer is that it just doesn’t make sense. Prostate cancer becomes more prevalent in men as they age, and that’s also when their testosterone levels decline. We almost never see it in men in their peak testosterone years, in their 20s for instance. We know from autopsy studies that 8% of men in their 20s already have tiny prostate cancers, so if testosterone really made prostate cancer grow so rapidly — we used to talk about it like it was pouring gasoline on a fire — we should see some appreciable rate of prostate cancer in men in their 20s. We don’t. So, I’m no longer worried that giving testosterone to men will make their hidden cancer grow, because I’m convinced that it doesn’t happen.
Bisphenol-A also known under the name of BPA is a chemical compound which is very widespread for manufacturing a wide spectrum of plastic items and aluminum cans. Many studies have already proven the fact that even the smallest amount of BPA is very harmful to the human health. This compound causes hormonal imbalance and even may lead to prostate cancer.
More people are realizing the functions and benefits of supplementing their respective workout regimen with testosterone boosters. As a result, these supps are gaining more and more popularity. The higher-demand for testosterone boosters started when numerous studies revealed the dangers of anabolic steroids, which may damage the natural production of testosterone.
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?

In this podcast, I will review the key biomarkers for achieving peak male health, along with the most potent and effective practices for optimizing biological variables for men's fertility and longevity. I will also unveil a host of little-known biohacks proven to enhance or restore peak testosterone and drive, along with how to practically implement a blend of ancestral wisdom and modern science to amplify sexual performance.
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.
“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."
Clinical trials of the effect of testosterone on glucose metabolism in men have occurred in diabetic and non-diabetic populations. Data specific to aging males is not available. A series of studies investigated the effects of testosterone or dihydrotestosterone given for 6 weeks or 3 months to middle aged, non-diabetic obese men (Marin, Holmang et al 1992; Marin, Krotkiewski et al 1992; Marin et al 1993). It was found that physiological treatment doses led to improved insulin resistance, as measured by the gold standard technique using a euglycemic clamp and/or serum glucose and insulin responses during glucose tolerance test. These improvements were associated with decreased central obesity, measured by computered tomography (CT) or waist-hip ratio, without reduced total fat mass. Insulin resistance improved more with testosterone than dihydrotestosterone treatment and beneficial effects were greater in men with lower baseline testosterone levels. Increasing testosterone levels into the supraphysiological range lead to decreased glucose tolerance.
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.
More specifically, saw palmetto is frequently used to suppress prostate growth and combat abnormal urine flow that results from an enlarged prostate. The reason it is believed that saw palmetto can combat prostate hyperplasia is based on some research indicating it may block an enzyme (5-alpha-reductase) that converts testosterone into dihydrotestosterone (DHT).[21]
“Our hypothesis was that testosterone would be good for the coronary arteries because we thought that by repleting testosterone to healthy levels there would be an improvement in the cholesterol panel and atherosclerosis burden. But what we found was the opposite, that atherosclerosis actually progresses faster under the influence of testosterone.”
Testosterone may decrease your chances of Alzheimer’s Disease. Several studies have linked low testosterone levels to an increased risk of Alzheimer’s disease.  In a 2010 study by the University of Hong Kong, researchers studied 153 Chinese men who were recruited from social centers. They were at least 55 years and older, lived in the community, and didn’t have dementia. Of those men, 47 had mild cognitive impairment — or problems with clear thinking and memory loss.
In fact, there is increasing evidence of the potential benefits of testosterone replacement therapy on multiple cardiovascular risk factors. This evidence recently has been comprehensively reviewed by Traish et al. in the Journal of Andrology.16 Although the full effects of testosterone replacement therapy on cardiovascular risk are yet to be established, the balance of emerging evidence from clinical studies suggests that testosterone replacement therapy in hypogonadal men may improve endothelial function, reduce proinflammatory factors, reduce hypertension, and improve the lipid profile.
This post can absolutely change your life, and probably help you avoid some pitfalls. Like shrunken balls. (I am not an expert in the synthetic anabolic testosterone drugs used by bodybuilders — they carry lots of risks but pack a big punch if you want to get swole. Bulletproof is all about having massive clean energy, looking good, and living a very long time…so anabolic steroids aren’t on my roadmap.)

And the ads have been working: The number of prescriptions written for testosterone have skyrocketed by more than 300 percent since 2001, reaching 7.2 million in 2013, according to a report published in 2016. Another study, published in JAMA in 2017, found that between 2009 and 2013, testosterone testing and treatment rose substantially in areas of the U.S. where such ads were very common.

Garlic is a very effective food that has been used for centuries in treating various physical ailments including heart problems and respiratory infections. What most people don’t know is that it is also a potent aphrodisiac and very effective in boosting sperm volume. It contains a compound called allicin which improves blood flow to the male sexual organs, increasing sperm production and semen volume.
Before a boy is even born, testosterone is working to form male genitals. During puberty, testosterone is responsible for the development of male attributes like a deeper voice, beard, and body hair. It also promotes muscle mass and sex drive. Testosterone production surges during adolescence and peaks in the late teens or early 20s. After age 30, it’s natural for testosterone levels to drop by about one percent each year.
46 year old whose suffered with low libido and all the related symptoms for over a decade. Finally had the courage to have a frank talk with dr. and urologist. Testosterone level 165, free testos level 3.6. Re-doing blood work again just to be sure in the next week or so, and will post updates then as things progress. Normal ranges are 300-1200 and 6 to 12.
Stick to protocols that stress large degrees of muscle mass and are moderate- to high-intensity. Additionally, more seasoned gym-goers may want to incorporate forced repetitions periodically into their programs, as testosterone increases have been observed with this type of training.14 Incorporating other post-failure training techniques such as dropsets or partials may similarly be associated with higher T production.

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.
