I highly recommend using a great essential amino acid mix post-exercise in order to boost testosterone.  These essential amino acids and especially the concentrated branched chain amino acids leucine, isoleucine and valine stimulate muscle protein synthesis.  Getting these amino acids in the post-workout window dramatically boosts testosterone production (14).  I like using our Amino Strong and will often recommend a scoop pre-workout and post-workout for the best muscle building, testosterone boosting benefits.
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]
Studies of the effects on cognition of testosterone treatment in non-cognitively impaired eugonadal and hypogonadal ageing males have shown varying results, with some showing beneficial effects on spatial cognition (Janowsky et al 1994; Cherrier et al 2001), verbal memory (Cherrier et al 2001) and working memory (Janowsky et al 2000), and others showing no effects (Sih et al 1997; Kenny et al 2002). Other trials have examined the effects of testosterone treatment in older men with Alzheimer’s disease or cognitive decline. Results have been promising, with two studies showing beneficial effects of testosterone treatment on spatial and verbal memory (Cherrier et al 2005b) and cognitive assessments including visual-spatial memory (Tan and Pu 2003), and a recent randomized controlled trial comparing placebo versus testosterone versus testosterone and an aromatase inhibitor suggesting that testosterone treatment improves spatial memory directly and verbal memory after conversion to estrogen (Cherrier et al 2005a). Not all studies have shown positive results (Kenny et al 2004; Lu et al 2005), and variations could be due to the different measures of cognitive abilities that were used and the cognitive state of men at baseline. The data from clinical trials offers evidence that testosterone may be beneficial for certain elements of cognitive function in the aging male with or without cognitive decline. Larger studies are needed to confirm and clarify these effects.
The biologically available part of total testosterone is called free testosterone, and it’s readily available to the cells. Almost every lab has a blood test to measure free testosterone. Even though it’s only a small fraction of the total, the free testosterone level is a pretty good indicator of low testosterone. It’s not perfect, but the correlation is greater than with total testosterone.

Hello – Has anybody here had their hair fall out after significantly increasing their T level? In 90 days of Clomiphene Citrate use my Total Testosterone went from 290 to 1100. and my Free T went from 50 to 202. Yes, it went way up! CC works. I have no idea why anybody would bother with gels and shots without giving this a chance. It costs almost nothing. so cheap.

For years, the recommendation has been to get a testosterone value early in the morning because levels start to drop after 10 or 11 a.m. But the data behind that recommendation were drawn from healthy young men. Two recent studies showed little change in blood testosterone levels in men 40 and older over the course of the day. One reported no change in average testosterone until after 2 p.m. Between 2 and 6 p.m., it went down by 13%, a modest amount, and probably not enough to influence diagnosis. Most guidelines still say it’s important to do the test in the morning, but for men 40 and above, it probably doesn’t matter much, as long as they get their blood drawn before 5 or 6 p.m.


Jeff- I read your post and I can relate to your problem. Perhaps you’ve already received some help but I can tell you this much. I recovered from prostate cancer about 2 yrs ago. My oncologist is also a graduate of Harvard like the doc that wrote this article. He put me on Axiron about 8 months ago after I complained to him of symptoms similar to you. He has no concerns that the T will cause me to get prostate cancer again. I do my 4 month check ups and have my T tested at that time along with my PSA. Everything is normal so far. My T count was initially 50 and now I am in the low 300 range. The Axiron has gotten me back to normal and then some!! I’m 58 and I told him at my last appt that I feel like I’m 40.
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).
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.
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.

Autopsy studies have found histological prostate cancer to be very common, with one series showing a prevalence of greater than fifty percent in men over age sixty (Holund 1980). The majority of histological cancers go undetected so that the clinical incidence of the disease is much lower, but it is still the most prevalent non-skin cancer in men (Jemal et al 2003). Prostate cancer is also unusual in comparison to other adult cancers in that the majority of those with the disease will die of other causes. Treatment of prostate cancer with androgen deprivation is known to be successful and is widely practiced, indicating an important role for testosterone in modifying the behavior of prostate cancer. In view of this, testosterone treatment is absolutely contraindicated in any case of known or suspected prostate cancer. The question of whether testosterone treatment could cause new cases of prostate cancer, or more likely cause progression of undiagnosed histological prostate cancer that would otherwise have remained occult, is an important consideration when treating ageing males with testosterone.

First is quality, Advanced BCAA’s are made from whey protein isolate. Typical free form amino acids are made from human hair and other not so favorable sources. In addition many free form amino acids are made in China. Secondly is the “form” the amino acids are in. Advanced BCAA’s are in peptide form. Meaning they are in di and trip peptide form. The body ABSORBS amino acids in di and trip peptide form, through the intestinal wall and into the blood stream. It is still not known whether free form amino acids are absorbed by the body. Keep in mind that free form amino acids supplements have been around since the 80’s. They have never been proved to help muscle recovery and grow. Di and tri peptides have been proven to be beneficial for muscle recovery.

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).
The study population in these TTrials included men aged 65 years or older with mean morning serum testosterone concentrations of 275 ng/dL or less and symptoms of impaired sexual function, physical function, or vitality. These trials were placebo-controlled and the testosterone treatment group received 1% testosterone gel at variable doses adjusted to maintain plasma testosterone at levels normal for young men (500-800 ng/dL).
Cardiovascular disease, and its underlying pathological process atherosclerosis, is an important cause of morbidity and mortality in the developed and developing world. Coronary heart disease in particular is the commonest cause of death worldwide (AHA 2002; MacKay and Mensah 2004). As well as increasing with age, this disease is more common in the male versus female population internationally, which has led to interest in the potential role of sex hormones in modulating risk of development of atherosclerosis. Concerns about the potential adverse effects of testosterone treatment on cardiovascular disease have previously contributed to caution in prescribing testosterone to those who have, or who are at risk of, cardiovascular disease. Contrary to fears of the potential adverse effects of testosterone on cardiovascular disease, there are over forty epidemiological studies which have examined the relationship of testosterone levels to the presence or development of coronary heart disease, and none have shown a positive correlation. Many of these studies have found the presence of coronary heart disease to be associated with low testosterone levels (Reviews: Jones, Jones et al 2003; Jones et al 2005).
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.
A team led by Dr. Joel Finkelstein at Massachusetts General Hospital investigated testosterone and estradiol levels in 400 healthy men, 20 to 50 years of age. To control hormone levels, the researchers first gave the participants injections of a drug that suppressed their normal testosterone and estradiol production. The men were randomly assigned to 5 groups that received different amounts (from 0 to 10 grams) of a topical 1% testosterone gel daily for 16 weeks. Half of the participants were also given a drug to block testosterone from being converted to estradiol.
Testosterone is responsible for increased muscle mass. Leaner body mass helps control weight and increases energy. For men with low testosterone, studies that treatment can decrease fat mass and increase muscle size and strength. Some men reported a change in lean body mass but no increase in strength. It’s likely you’ll see the most benefits when you combine testosterone therapy with strength training and exercise.
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.

Finally, related to the point about competitiveness above, studies have shown that testosterone levels not only go up before a fight or competition, they increase after each win, and this gives the winner a much higher probability of winning his next round, and the next round after that, even against evenly matched competitors. This is called the “winner-effect,” and John Coates, author of The Hour Between Dog and Wolf: Risk Taking, Gut Feelings and the Biology of Boom and Bust, explains why it works:
Great product. I'm a 41 yearold and found myself with low energy constantly. Since taking these pills I'm more energized and don't get home from work and just sit around the house anymore. Bonus the wife has been loving the extra benefit that they are giving us. I never thought I had a problem in that area but since I started taking these I've noticed a way longer lasting performance time.
What makes TestoFuel different from other testosterone boosters on the market is that the company is constantly researching and updating the ingredients. So, you know you are getting a product that has been formulated using the latest clinical studies. Unlike most other companies that formulate a product and update it every 3 – 5 years or never at all.

Herein lies the problem.  DHT is an extremely powerful androgen, significantly more potent than testosterone.  Somehow, fenugreek causes increases in muscle mass and libido while reducing DHT.  I often argue on the site that it is not exactly increased testosterone that you want.  You want the blessings of a high testosterone level: physical fitness, libido, and high energy levels.  If fenugreek can bestow these upon you, why do you need the testosterone?
Thanks for reaching out buddy. Sorry to hear about your situation. First off, what I’d suggest is to forget about creams, they are a waste of money unless you are trying to moisturize your body – which I guess you’re not. As for estrogen blockers, the same goes here – but testosterone boosters on the other hand, they work with your body instead of against it to give you everything your body is missing – it sounds like it’s the missing piece to your puzzle. Bear in mind Graham, you’ll need to pay close attention to your diet – aim to cut down on refined carbohydrates and simple sugars – these are terrible for testosterone production and weight gain. If you drink more water, eat a balanced diet, and exercise occasionally while supplementing with testofuel.com you’ll soon be back on track. All the best!
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.

Testosterone makes you angry. This is probably the most common myth about T. The reality is that there’s no concrete evidence that high testosterone levels cause anger and violent outbursts. In fact, the opposite might be true; low testosterone, not high T, is what causes anger and irritability in men. As discussed above, having low T levels has been linked to depression in men and it just so happens that two of the primary symptoms of depression in men are increased angry outbursts and irritability. So if you’re chronically angry, you might be depressed, and you might be depressed because you have low T. As I mentioned above, I became less moody and irritable during my experiment, which I attribute to the boost in my testosterone levels.

If you have low testosterone and are prescribed testosterone therapy by your doctor, it does not increase your risk for getting prostate cancer. However, in some patients with existing prostate cancer, adding testosterone hormone therapy can make the cancer grow faster. Men with low testosterone levels are actually more likely to get prostate cancer than men with normal prostate levels. You need to discuss these details with your physician and make the best decision for you.

But when a premenopausal woman’s testosterone levels are too high, it can lead to polycystic ovary syndrome (PCOS), a condition that increases the risk of irregular or absent menstrual cycles, infertility, excess hair growth, skin problems, and miscarriage. High levels of testosterone in women, whether caused by PCOS or by another condition, can cause serious health conditions such as insulin resistance, diabetes, high cholesterol, high blood pressure, and heart disease.
