In a subsequent study of 345 men with normal PSA and low testosterone, we found the cancer rate was similar: 15%. And we had a large enough group to look at the impact of testosterone on cancer risk. For men whose total testosterone or free testosterone value was in the lowest third, the odds of having a positive biopsy were double the odds in the rest of the men. That’s the first evidence that low testosterone may be an independent predictor for the development of prostate cancer.
In addition to weightlifting, studies have shown that HIIT workouts can also help boost testosterone levels. For those of you who don’t know, HIIT stands for high-intensity interval training. It calls for short, intense bursts of exercise, followed by a less-intense recovery period. You repeat with the intense/less-intense cycle several times throughout the workout. In addition to increasing T, HIIT has been shown to improve athletic conditioning and fat metabolism, as well as increase muscle strength.
The rise in testosterone levels during competition predicted aggression in males but not in females.[90] Subjects who interacted with hand guns and an experimental game showed rise in testosterone and aggression.[91] Natural selection might have evolved males to be more sensitive to competitive and status challenge situations and that the interacting roles of testosterone are the essential ingredient for aggressive behaviour in these situations.[92] Testosterone produces aggression by activating subcortical areas in the brain, which may also be inhibited or suppressed by social norms or familial situations while still manifesting in diverse intensities and ways through thoughts, anger, verbal aggression, competition, dominance and physical violence.[93] Testosterone mediates attraction to cruel and violent cues in men by promoting extended viewing of violent stimuli.[94] Testosterone specific structural brain characteristic can predict aggressive behaviour in individuals.[95]
Vitamin D3. Vitamin D3 actually isn’t a vitamin, it’s a hormone — a really important hormone that provides a whole host of health benefits. Our bodies can naturally make vitamin D from the sun, but recent studies have shown that many Westerners are vitamin D3 deprived because we’re spending less and less time outdoors. When we do decide to venture outside, we slather our bodies with sunscreen, which prevents the sun reaching our skin to kick-off vitamin D3 production. If you’re not getting enough sun, you may have a vitamin D3 deficiency, which may contribute to low T levels. If you think you need more vitamin D3, supplement it with a pill. Studies have shown that men who take this supplement see a boost in their testosterone levels. Because I have a darker complexion — which makes me prone to Vitamin D3 deficiency — I took 4,000 IU of vitamin D3 in the morning.
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.
In males, the testosterone test can help find the reason for sexual problems, like reduced sex drive or erectile dysfunction. If you’re having a hard time getting your partner pregnant, the test can tell if your blood testosterone level is low. It can also screen for problems with the hypothalamus or pituitary gland. This controls how much testosterone your body makes.
For this reason, after the 2008 financial market meltdown, some commentators put the blame for the crash on the male-dominated profession, arguing that men take too many risks, and the economy would do better and be more stable if it was run by women. Of course, risk-taking does come with inherent risk, but it has also been responsible for the lion’s share of society’s progress and innovation since the dawn of time. Financial markets would likely not exist – period – without testosterone-driven risk-taking.
Testosterone improves not just your sex drive, but it also enhances exercise drive, energy for work, mental sharpness, muscle repair, and revs your metabolism to help with weight control. Although improving testosterone levels has not yet been shown to increase lifespan, having a healthy testosterone level improves quality of life for both men and women.
As you cut these dietary troublemakers from your meals, you need to replace them with healthy substitutes like vegetables and healthy fats (including natural saturated fats!). Your body prefers the carbohydrates in micronutrient-dense vegetables rather than grains and sugars because it slows the conversion to simple sugars like glucose, and decreases your insulin level. When you cut grains and sugar from your meals, you typically will need to radically increase the amount of vegetables you eat, as well as make sure you are also consuming protein and healthy fats regularly.

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.


Grape seed extract is another ingredient with not enough research to suggest a dosage. Grape seed extract can interact with drugs like “blood thinners, NSAID painkillers (like aspirin, Advil, and Aleve), certain heart medicines, cancer treatments, and others.” If this sounds like you (or if you ever pop an Advil to clear off a headache), you’ll need to speak with a doctor to make sure this supplement is safe to take.
A couple years ago I was having a problem with my thighs burning when walking up stairs. I noticed the muscles in my legs looking smaller. So I had my doc to check my T levels , and it was under 100. So she started me on testosterone injections weekly 200mg . After several injections I felt great , muscles in legs came back , lots of energy everything good . Leveled out at 3 injections a week 100mg , had a T level of 550 . So I go in for my scheduled injection and they tell me there out of testosterone . I might mention, this is a health care facilility that gives financial assistant if needed. And they have 3 or doctors and a nurse practitioner, which was who I was seeing . So I went on to check back often and got the same reply , were out of supply . So finally after months of the same , I gave up . I started loosing wait and my nerves got bad . Was having panic attacks etc. but I was coming off Prozac at the same time so I blamed it all on that. I was so bad with my nerves I ended up in the ER while on vacation . Doc there put me on a med for stress which I’m still using . After close to a year I checked back with the place I was getting TRT and they were resupplyed with testosterone. So I started back up because of low sex drive and ED. My first injection of 200mg was just short of a Marical , nerves felt great ED gone , had a sex drive , lot of energy . Then after 7 days or so all gone bad nerves started back up . He had me scheduled for anouther injection in 4 weeks 100mg . I went in for injection and after a couple days started feeling a little better . Then same thing as before about 7 days later nerves and everything else as before got worse . 3 weeks later I finally got a appt. with this different doc then I use to have . Told him the problems I was having , which included a horrible down mood , no energy . He decided to start injections every 2 weeks and upped the dose slitley. It’s been 5 days and already noticing ED problem reaccuring . He’s worried about the threat of prostate cancer. And doesn’t want to add any more injection to the schedule. I guess I’m going to have to start seeing the nurse practitioner who seemed to be more liberal and informed about TRT. I feel once a week injection is what it will take to get feeling good again. I’m 57 now with good health . Just need to get my T level on track with a doctor that will listen to how his patient is feeling . My last T level was at 365 . I failed to mention before I started the injections I was on androgel Dailey , 5 pumps a day . Then he gave me the injection of 200mg test . That’s when I felt fantastic for about a week or so . Then down hill . And I wanted to switch because the injection just seem so much better and they are . I noticed a big difference.
A testosterone booster is a natural supplement used by people (mostly men) to boost their testosterone levels. They work in a few different ways. First, they often impact the hormones related to testosterone and cause more of the hormones to circulate in the blood. They also can block estrogen production, which is commonly called a female sex hormone.
‘Testosterone boosting’ products  - found online, or in health food or body-building shops, these products claim to boost testosterone levels if you buy them. The majority of these products will not have the effect you want and are not worth spending money on. Any of these products that do have a real effect may have a form of prescription medication in which is both dangerous and illegal.

Overall there is evidence that testosterone treatment increases lean body mass and reduces obesity, particularly visceral obesity, in a variety of populations including aging men. With regard to muscle changes, some studies demonstrate improvements in maximal strength but the results are inconsistent and it has not been demonstrated that these changes lead to clinically important improvements in mobility, endurance or quality of life. Studies are needed to clarify this. Changes in abdominal obesity are particularly important as visceral fat is now recognised as predisposing the metabolic syndrome, diabetes and cardiovascular disease.
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.
The effect excess testosterone has on the body depends on both age and sex. It is unlikely that adult men will develop a disorder in which they produce too much testosterone and it is often difficult to spot that an adult male has too much testosterone. More obviously, young children with too much testosterone may enter a false growth spurt and show signs of early puberty and young girls may experience abnormal changes to their genitalia. In both males and females, too much testosterone can lead to precocious puberty and result in infertility. 
In addition to conjugation and the 17-ketosteroid pathway, testosterone can also be hydroxylated and oxidized in the liver by cytochrome P450 enzymes, including CYP3A4, CYP3A5, CYP2C9, CYP2C19, and CYP2D6.[159] 6β-Hydroxylation and to a lesser extent 16β-hydroxylation are the major transformations.[159] The 6β-hydroxylation of testosterone is catalyzed mainly by CYP3A4 and to a lesser extent CYP3A5 and is responsible for 75 to 80% of cytochrome P450-mediated testosterone metabolism.[159] In addition to 6β- and 16β-hydroxytestosterone, 1β-, 2α/β-, 11β-, and 15β-hydroxytestosterone are also formed as minor metabolites.[159][160] Certain cytochrome P450 enzymes such as CYP2C9 and CYP2C19 can also oxidize testosterone at the C17 position to form androstenedione.[159]

My favorite overall tool to manage stress is EFT (Emotional Freedom Technique), which is like acupuncture without the needles. It's a handy, free tool for unloading emotional baggage quickly and painlessly, and so easy that even children can learn it. Other common stress-reduction tools with a high success rate include prayer, meditation, laughter and yoga, for example. Learning relaxation skills, such as deep breathing and positive visualization, which is the "language" of the subconscious.
After years of low libido,ED and just general lack of energy I found a urogist will to look at my symptoms. Turned out my testosterone level was 135 so I started on testosterone. Had a great improvement on everything I was having issues plus just a lot happier. My Dr. did PSA every 6 months and my PSA over almost 2 years went from 1.16 to 1.67, still pretty low for 56YOA He wanted to do a biopsy and he found 1 out of 12 cores 60%, GS3X3. I had an MRI and found a .5cm cancer, clean margins, perfectly round and dead center of the prostate.I’m doing active surviellance and the DR wants to start me on Finasteride and continue TRT. I like to believe that the years of low testosterone help the cancer to develope and the twice yearly testing of PSA by the doctor because of therapy caught it very early.I’m not too sure about TRT and Finasteride together.
Testosterone begins with cholesterol. In fact, every single sex hormone you make you synthesize from cholesterol – that’s one reason a “heart healthy” low-fat, low-cholesterol diet limits your performance. Fat and cholesterol don’t make you fat. They give your body the building blocks to create abundant testosterone and other sex hormones, which actually makes you lose weight and build muscle, especially if your current testosterone levels are low [1].

Testosterone does a lot more than you’d think, whether we’re talking about male or female biology. It’s the hormone that helps you burn fat, build muscle [1], and increase your sex drive [2], and its power doesn’t stop there. Keeping your testosterone levels in a normal range can make you happier, too [3], and testosterone can even improve your cardiovascular health and decrease your risk of mortality (from all causes!), according to a study of 83,000 older men who underwent testosterone replacement therapy [4].

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.
This evidence, together with the beneficial effects of testosterone replacement on central obesity and diabetes, raises the question whether testosterone treatment could be beneficial in preventing or treating atherosclerosis. No trial of sufficient size or duration has investigated the effect of testosterone replacement in primary or secondary prevention cardiovascular disease. The absence of such data leads us to examine the relationship of testosterone to other cardiovascular risk factors, such as adverse lipid parameters, blood pressure, endothelial dysfunction, coagulation factors, inflammatory markers and cytokines. This analysis can supply evidence of the likely effects of testosterone on overall cardiovascular risk. This has limitations, however, including the potential for diverging effects of testosterone on the various factors involved and the resultant impossibility of accurately predicting the relative impact of such changes.
Testosterone boosters are used by many athletes worldwide to achieve a significant muscle mass increase within a short period of time.[1] However; one cannot be completely confident in terms of the quality and efficacy of such products because of several reasons, such as the possibility of bad storage conditions and originating from an unreliable source. Over the years, some consumers of testosterone boosters have complained of kidney and liver abnormalities that could be linked to their use of boosters.[10] Cases of erroneous product administration have occurred in the past as athletes may not follow the instructions on the label fully, which can lead to many side effects.[11] In the present case, a man was admitted to a hospital because of a severe abdominal pain. The pain was later found to be caused by liver injury. The diagnosis confirmed that the levels of the key hepatic enzymes were markedly elevated. The medical complications observed were found to have occurred following the consumption of two courses of a commercial testosterone booster. According to researchers based in the US, about 13% of the annual cases of acute liver failure are attributable to idiosyncratic drug- and/or supplement-induced liver injury.[12] Marked increase in the levels of ALT, AST, and gamma-glutamyl transferase was observed after consuming the first course of the commercial testosterone booster, and they started to decline after the 2nd and 3rd course. This abruptly increases the levels of liver enzymes after the first course may be attributed to the interruption effect of commercial testosterone booster on liver function as a result of the effects of its ingredients.
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.
Hello there Abraham. My doc and you know each other well. We reside in Richmond, VA. Doc told me to inject my weekly Cypionate into sub fat for longer absorption, with reference you shared this info him with him. I have been his TRT patient for 10 years now. He is the best. I wont mention names. Please point me to a study showing the results of testosterone absorption from fat.
In a recent study of male workers, men with low testosterone levels had an increased chance of severe erectile dysfunction (Kratzik et al 2005), although such a link had not been found previously (Rhoden et al 2002). Certainly erectile dysfunction is considered part of the clinical syndrome of hypogonadism, and questions regarding erectile dysfunction form part of the clinical assessment of patients with hypogonadism (Morley et al 2000; Moore et al 2004).
"A lot of the symptoms are mirrored by other medical problems," Hedges says. "And for a long time, we were not attributing them to low testosterone, but to diabetes, depression, high blood pressure, and coronary artery disease. But awareness and appreciation of low testosterone has risen. We recognize now that low testosterone may be at the root of problems."
