There is a negative correlation of testosterone levels with plasminogen activator inhibitor-1 (PAI-1) (Glueck et al 1993; Phillips 1993), which is a major prothrombotic factor and known to be associated with progression of atherosclerosis, as well as other prothrombotic factors fibrinogen, α2-antiplasmin and factor VII (Bonithon-Kopp et al 1988; Glueck et al 1993; Phillips 1993; De Pergola et al 1997). There is a positive correlation with tissue plasminogen activator (tPA) which is one of the major fibrinolytic agents (Glueck et al 1993). Interventional trials have shown a neutral effect of physiological testosterone replacement on the major clotting factors (Smith et al 2005) but supraphysiological androgen administration can produce a temporary mild pro-coagulant effect (Anderson et al 1995).
February 22, 2018 - Since our last review, the manufacturers of two of our top picks have gone out of business, and some new testosterone boosters have entered the arena. We’ve updated this review to evaluate the current field of testosterone supplements, as well as beef up analysis on what kind of results you can expect from t-boosters. Our only current top pick, Beast Sports Nutrition, is a new player in the industry that contains all four of the ingredients with studies showing a positive effect on testosterone.
Testosterone is a hormone that regulates the sex organs, metabolism, bone density, and other bodily functions. Though it affects primarily men, both sexes can experience low testosterone (Low T). Fortunately, lifestyle choices play the biggest part in testosterone levels, so you may be able to increase your testosterone. However, it’s best to see a doctor if your symptoms are new or you aren’t feeling better after making changes.
Some boys even develop enlarged testicles and penis, armpit or pubic hair, as well as facial hair as early as age nine! Early puberty is not something to be taken lightly because it can significantly influence physical and psychological health, including an increased risk of hormone-related cancers. Precocious sexual development may also lead to emotional and behavioral issues, such as:
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.
Scientists in Italy found that subjects who consumed roughly 3 grams of D-AA for 12 days observed a 42 percent increase in testosterone levels. The researchers also noted that the D-AA group still had 22 percent more testosterone than the placebo group three days after they stopped supplementing. Conversely, a more recent article published in Nutrition Research found no increase in testosterone levels in resistance-trained males after supplementing with 3 grams of D-AA for 28 days.
Estrogen is important in men, but too high of a level has all sorts of negative consequences – ranging from heart attacks to prostate cancer (32 & 33). The balance between testosterone and estrogen (or estradiol) is critical for a man. If the ratio is out and estrogen starts to dominate you run into all sorts of issues – such as breast cell growth, prostate enlargement and of course lower testosterone.
Below, we have the runners up. They are still potent supplements and we’ve had great runs with them. Keep in mind though, there are a LOT of test boosters we’ve tried that are not making this list. We wish we could talk poorly about specific supplements, but that’s a legal issue; so instead we only focus on the best supplements we’ve taken. If we took it and didn’t like it – we wont write about it.
Testosterone [Figure 1] is the main male sex hormone. It is responsible for male sexuality and is the main hormone-producing the features associated with masculinity such as substantial muscle mass, facial hair, libido, and sperm production. Besides, the hormone has other vital functions as the basic chemical composition of testosterone is steroidal; and steroids are known to have significant physiological, as well as psychological, effects in male individuals, especially adults. Testosterone production is reduced gradually in men starting from the age of 30. Hence, testosterone blood concentrations slowly diminish as age progresses. As a result, men may experience a number of physiological and psychological events, such as a lack of sex-drive, erectile dysfunction, acute depression, fatigue, low energy levels, and insomnia.
Ashwagandha is most prominently used for its powerful adaptogen properties. Adaptogens refer to natural substances that can help your body adapt to stress. Stress has become something of a modern epidemic, and it is more than just feeling bad or annoyed. Stress has real effects on your physiology, thanks in part to the chemical cortisol. Cortisol is designed to put your body in a fight or flight response characteristic of stressful situations. However, chronic stress causes consistently high levels of cortisol, which can cause negative effects, including increased blood sugar, weight gain and even reduced testosterone levels. As an adaptogen, ashwagandha can help to regulate cortisol and curb many of its effects.
For example, the study published in Obesity Research tells that the scientists measured testosterone levels in two groups of middle-aged men with obesity. One group underwent a 16-week weight loss program, while the second group did nothing. Each participant of the first group lost 20 kg on the average. And these participants experienced a significant increase in testosterone levels. So, the fight against overweight is very important for those who want to overcome testosterone deficiency. But starvation is strictly forbidden because this is a stressful situation which leads to the sharp decline in T levels.
Even before the study yields its findings, Dr. Swerdloff said a few important points should be emphasized. "I want to make it clear that this is not a made-up disease," he said. "It is well known in younger men that if you have a failure to produce normal testosterone, there are certain signs and symptoms that create a kind of syndrome. Treatment for low testosterone has been documented to be beneficial."
Type 2 diabetes is an important condition in terms of morbidity and mortality, and the prevalence is increasing in the developed and developing world. The prevalence also increases with age. Insulin resistance is a primary pathological feature of type 2 diabetes and predates the onset of diabetes by many years, during which time raised serum insulin levels compensate and maintain normoglycemia. Insulin resistance and/or impaired glucose tolerance are also part of the metabolic syndrome which also comprises an abnormal serum lipid profile, central obesity and hypertension. The metabolic syndrome can be considered to be a pre-diabetic condition and is itself linked to cardiovascular mortality. Table 1 shows the three commonly used definitions of the metabolic syndrome as per WHO, NCEPIII and IDF respectively (WHO 1999; NCEPIII 2001; Zimmet et al 2005).
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.
There are studies that show Soy consumption in humans leads to lower sperm count, but unfortunately they did not look at testosterone levels in the study (40). This (41) particular study compared the estrogen production of men drinking soy protein to those drinking whey. After two weeks they found the estradiol levels were equal, however soy drinkers had LOWER Testosterone levels and HIGHER cortisol levels (both bad).
Dr. Ronald Swerdloff, chief of the endocrinology division at the Harbor-UCLA Medical Center and a professor of medicine at UCLA's David Geffen School of Medicine, served on the panel of experts who developed the Endocrine Society's guidelines. He is also the principal investigator for one of the 12 sites of The Testosterone Trial in Older Men, a nationwide study funded mainly by the National Institute on Aging. The study of 800 men over age 65 with low testosterone is looking at whether men using AndroGel for one year, compared to placebo, will show improvements in walking speed, sexual activity, vitality, memory, and anemia. The study will be completed in June 2015.

Once you have surpassed your early twenties, natural testosterone levels slowly begin to decline. This is a natural occurrence which occurs in all men, however can be prevented to some extent by ensuring your diet is rich in vitamins, minerals and quality fats. You can also supplement with a Natural Testosterone Booster which will work by encouraging your body to produce more Testosterone, back up to levels you could produce in your younger years.
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.
If a man's testosterone looks below the normal range, there is a good chance he could end up on hormone supplements—often indefinitely. "There is a bit of a testosterone trap," Dr. Pallais says. "Men get started on testosterone replacement and they feel better, but then it's hard to come off of it. On treatment, the body stops making testosterone. Men can often feel a big difference when they stop therapy because their body's testosterone production has not yet recovered."
