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.
Both Beast Sports’ Super Test and iSatori’s ISA-Test contain a proprietary blend, which means they don’t disclose the amount of each and every ingredient in the mix. This is only a problem if there is an ingredient tucked into a proprietary blend for which we need to know an amount, like magnesium and zinc. While none of the ingredients in Beast Sports’s proprietary blend raised any red flags, iSatori’s blend contains melatonin, a hormone that helps regulate sleep. Melatonin is an ingredient that has a hard upper limit — Healthline suggests at most 10mg for an adult — and even lower doses can interact poorly with many medications. Since we can’t confirm whether the amount of melatonin in iSatori’s proprietary blend is under 10mg, we cut iSatori.
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.

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


I am a 43 year old and have undergone pituitary sectioning/surgery twice. Since then i have been using the testoterone gel daily for 12 years without any problem. However, i still have pituitary tumor and also diagnosed with colon cancer. I am thinking of stopping the HRT because i felt it is worsening the illness. I would be glad if you could advice me of the risk of stopping the treatment.
Testosterone is a hormone that is produced primarily in the testicles for men and the ovaries and adrenal glands for women. This hormone is essential to the development of male growth and masculine characteristics. For women, testosterone comes in much smaller amounts. Testosterone production increases about 30 times more during adolescence and early adulthood. After early adulthood, it’s natural for levels to drop slightly each year. Your body may see a one percent decline after you’re 30 years old.

Testosterone is an anabolic steroid hormone that plays a critical role in metabolism, sex drive, muscle building, mood regulation, memory & cognitive function.  Normal testosterone levels play a huge role in maintaining optimal weight as well as reducing risk of degenerative diseases such as osteoporosis, heart disease, diabetes, & certain cancers (1, 2, 3).

In summary, low testosterone levels are linked to the presence of numerous cardiovascular risk factors. Testosterone treatment acts to improve some of these factors, but effects may vary according to pre- and post-treatment testosterone levels, as well as other factors. There is little data from trials specific to aging males. Appropriately-powered randomized controlled trials, with cardiovascular disease primary endpoints, are needed to clarify the situation, but in the meantime the balance of evidence is that testosterone has either neutral or beneficial effects on the risk of cardiovascular disease in men. It is particularly important to define the effect of testosterone treatment on cardiovascular disease in view of its potential use as an anti-anginal agent.


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).
In many of the studies we found, those who saw the most improvement in health, testosterone, or muscle gain were those with existing nutrient or vitamin deficiencies. This means that some gains may be due more to dietary changes and generally restoring nutrient and vitamin levels than any one magic ingredient, but also that making sure your diet includes healthy amounts of nutrients should be your first step.
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:
Recently my testosterone level came back at 380. and I am on max dose of 1% 8 pumps per day. The Dr. put me on 1.62% 8 pumps once a day and I will test in a few weeks to see how my level has changed. The issue is I am afraid of is putting 4 pumps a day in each shoulder and upper arm. Has anyone used this much to get there levels up? I am very fit and workout 4 times a week . The other issue is cost because 1.62% is not available 1n generic and cost has skyrocketed.
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.
I’ve also got a thyroid nodule (benign), and should have it burned out very soon. So I’ve been battling a little more than low T for several years to say the least… a lot of the symptoms of low T can overlap with hyper and/or hypothyroidism… I highly recommend having your TSH, T4 and T3 levels checked along with your Testosterone for anyone experiencing symptoms.
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. 

A: There are no over-the-counter products approved by the U.S. Food and Drug Administration (FDA) to increase testosterone levels. There are several prescription medication options available. Please consult with your health care provider in regards to your testosterone levels and to determine which treatment option best meets your individual needs. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Kristen Dore, PharmD

D-AA:  D-Aspartic Acid has been known to increase libido and sex drive as well as fertility in infertile men. D-AA was the craze a few years back but the issue found was that after a month of use, the results started to diminish.  Also, if you currently have normal levels of testosterone, D-AA won’t do much good for you in terms of an increase in T-levels. 
Testosterone is an androgen hormone produced by the adrenal cortex, the testes (in men), and the ovaries (in women). It is often considered the primary male sex hormone. Testosterone stimulates the development of male secondary sex characteristics (like body hair and muscle growth) and is essential in the production of sperm. In women, testosterone plays a role in egg development and ovulation.

My genetic make-up is 47XXY. I was diagnosed in September, 1976, and have been on some kind of T-therapy since – injections, pills, gels, patches, pellets, now back on injections. At this time, now, I inject 1/2cc deep IM, every 7-8 days. I suffered a blood clot between my knee and my groin (right leg) in January, 2017. I am now on Eliquis through June, 2017. My blood has always been quick to coagulate. I’ve read through all of this, and only found mention of blood clots sporadically in relation to T-therapy. I’m 70 yoa, have never had a problem before. Can you give me any info I can pass along to my doctor? Thank you.


Hello..was prescribe andro gel 1.62 for about 2 years..borderline low..At time 54 year old now 57..a year ago switched doctors..new doctor would not prescribe andro gel..without me stopping use and then being checked after 6 months..it’s been a year..by the way felt great while on it much more energy. .did notice some hair receding. .but felt stronger..my question is..by using andro gel ..did I turn off my body’s natural ability to make testosterone as using andro gel..if so what do I need to do too turn my body on if my doctor does not renew therapy. .by way the past without andro gel…little too no energy..weight gain of 40 lbs..especially around the belly..thank you for your time and reply
As you can see, the entire workout is only 20 minutes. Twenty minutes! That really is a beautiful thing. And within those 20 minutes, 75 percent of that time is warming up, recovering or cooling down. You're really only working out intensely for four minutes. It's hard to believe if you have never done this that you can actually get that much benefit from four minutes of exercise. That's all it is.
Saw palmetto and testosterone facts Testosterone is the primary male sex hormone. Boosting its levels can have many effects, such as promoting muscle growth and improving libido. Saw palmetto, a plant resembling the leaves of a palm tree, may boost testosterone levels and offer other health benefits. Learn more about saw palmetto and testosterone here. Read now
In the hepatic 17-ketosteroid pathway of testosterone metabolism, testosterone is converted in the liver by 5α-reductase and 5β-reductase into 5α-DHT and the inactive 5β-DHT, respectively.[1][155] Then, 5α-DHT and 5β-DHT are converted by 3α-HSD into 3α-androstanediol and 3α-etiocholanediol, respectively.[1][155] Subsequently, 3α-androstanediol and 3α-etiocholanediol are converted by 17β-HSD into androsterone and etiocholanolone, which is followed by their conjugation and excretion.[1][155] 3β-Androstanediol and 3β-etiocholanediol can also be formed in this pathway when 5α-DHT and 5β-DHT are acted upon by 3β-HSD instead of 3α-HSD, respectively, and they can then be transformed into epiandrosterone and epietiocholanolone, respectively.[157][158] A small portion of approximately 3% of testosterone is reversibly converted in the liver into androstenedione by 17β-HSD.[156]
D-Aspartic acid is a natural amino acid involved in the synthesis and release of testosterone, which research shows can be used as a testosterone booster for infertile men. One 90-day study gave D-Aspartic acid to men with impaired sperm production, and found their sperm count rose from 8.2 million sperm per ml to 16.5 million sperm per ml, more than a 100 per cent increase.
Mental status changes including excess aggression are a well known phenomenon in the context of anabolic steroid abuse (Perry et al 1990). An increase in self-reported aggressive behaviors have also been reported in one double blind placebo controlled trial of testosterone in young hypogonadal men (Finkelstein et al 1997), but this has not been confirmed in other studies (Skakkebaek et al 1981; O’Connor et al 2002). Aggression should therefore be monitored but in our experience is rarely a significant problem during testosterone replacement producing physiological levels.

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?
Present in much greater levels in men than women, testosterone initiates the development of the male internal and external reproductive organs during foetal development and is essential for the production of sperm in adult life. This hormone also signals the body to make new blood cells, ensures that muscles and bones stay strong during and after puberty and enhances libido both in men and women. Testosterone is linked to many of the changes seen in boys during puberty (including an increase in height, body and pubic hair growth, enlargement of the penis, testes and prostate gland, and changes in sexual and aggressive behaviour). It also regulates the secretion of luteinising hormone and follicle stimulating hormone. To effect these changes, testosterone is often converted into another androgen called dihydrotestosterone.
