I am still on T therapy. But here’s what pisses me off: No one tells you that you will be hooked on the drug virtually forever! Don’t ever stop it abruptly! I did and I had a major crash: physically and emotionally. I went into the darkest depression ever…and I was lacking in energy so much that I had to have 4 naps a day…just to get through the day. I was also robbed of any initiative to do anything.
Andy – If you take testosterone, your hypothalamus will notice an abundance of testosterone in your system and will instruct your pituitary gland not to send LH and FSH to your testicles. If you’re testicles are not receiving these two hormones, they will stop making testosterone. If you quit testosterone call turkey, you will likely fall back to your baseline level fairly quickly. There is a protocol however to get back to your normal production much quicker should you choose to quit therapy.
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.
The effects of testosterone in humans and other vertebrates occur by way of multiple mechanisms: by activation of the androgen receptor (directly or as DHT), and by conversion to estradiol and activation of certain estrogen receptors.[113][114] Androgens such as testosterone have also been found to bind to and activate membrane androgen receptors.[115][116][117]
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.

Tribulus terrestris is an ingredient commonly presented as improving testosterone levels, but has not been found to be more effective than a placebo or possess any testosterone increasing properties. WebMD cautions that it interferes with Lithium and diabetes medications, and in general, not enough is known about tribulus terrestris to recommend a dosage for anyone.
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.

Studies also show a consistent negative correlation of testosterone with blood pressure (Barrett-Connor and Khaw 1988; Khaw and Barrett-Connor 1988; Svartberg, von Muhlen, Schirmer et al 2004). Data specific to the ageing male population suggests that this relationship is particularly powerful for systolic hypertension (Fogari et al 2005). Interventional trials have not found a significant effect of testosterone replacement on blood pressure (Kapoor et al 2006).

For example, in February 2017, scientists reported on trials involving men over age 65 who had low testosterone due to aging. Each trial included a different number of men depending on the subject of the research. Roughly half of the participants received testosterone therapy for a year; the rest underwent a placebo treatment. The researchers discovered the following:
This particular product contains the largest dose of D-Aspartic Acid making it a highly effective muscle and strength builder. In addition, TestoFuel contains optimum doses the proven ingredients of Vitamin D, Oyster Extract, Zinc, Magnesium, Vitamin B6, Vitamin K2, Fenugreek and Siberian Ginseng. And you won’t get filler ingredients with this one like you do with many others.

In order to discuss the biochemical diagnosis of hypogonadism it is necessary to outline the usual carriage of testosterone in the blood. Total serum testosterone consists of free testosterone (2%–3%), testosterone bound to sex hormone binding globulin (SHBG) (45%) and testosterone bound to other proteins (mainly albumin −50%) (Dunn et al 1981). Testosterone binds only loosely to albumin and so this testosterone as well as free testosterone is available to tissues and is termed bioavailable testosterone. Testosterone bound to SHBG is tightly bound and is biologically inactive. Bioavailable and free testosterone are known to correlate better than total testosterone with clinical sequelae of androgenization such as bone mineral density and muscle strength (Khosla et al 1998; Roy et al 2002). There is diurnal variation in serum testosterone levels with peak levels seen in the morning following sleep, which can be maintained into the seventh decade (Diver et al 2003). Samples should always be taken in the morning before 11 am to allow for standardization.

Testosterone is included in the World Health Organization's list of essential medicines, which are the most important medications needed in a basic health system.[111] It is available as a generic medication.[10] The price depends on the form of testosterone used.[112] It can be administered as a cream or transdermal patch that is applied to the skin, by injection into a muscle, as a tablet that is placed in the cheek, or by ingestion.[10]
In summary it’s important to know that this topic is still hotly debated, and there are a lot of inconsistencies in the data. We do know that soy contains phytoestrogens and does seem to have a lot of affects on the body, including some studies that show decreased Testosterone levels. For that reason (and the fact that it tastes like ass) I avoid it, and I recommend you also avoid it (in particular soy isolates!) if you’re seeking higher testosterone.
When patients ask about risks, I remind them that they already have testosterone in their system and that the goal of testosterone treatment is to restore its concentration back to what it was 10 or 15 years previously. And the molecule itself that we give is identical to the one that their bodies make naturally, so in theory, everything should be hunky-dory. But in practice, there are always some curveballs.
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.
“Poor lifestyle can mimic the symptoms of low testosterone and can actually cause low testosterone as well,” says Hodzovic. “The main culprits include lack of sleep, excessive stress, too little or too much exercise and too little or too much body fat. Getting healthy and active and eating a balanced nutritious diet along with enough sleep are the most important things to do.
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 1927, the University of Chicago's Professor of Physiologic Chemistry, Fred C. Koch, established easy access to a large source of bovine testicles — the Chicago stockyards — and recruited students willing to endure the tedious work of extracting their isolates. In that year, Koch and his student, Lemuel McGee, derived 20 mg of a substance from a supply of 40 pounds of bovine testicles that, when administered to castrated roosters, pigs and rats, remasculinized them.[183] The group of Ernst Laqueur at the University of Amsterdam purified testosterone from bovine testicles in a similar manner in 1934, but isolation of the hormone from animal tissues in amounts permitting serious study in humans was not feasible until three European pharmaceutical giants—Schering (Berlin, Germany), Organon (Oss, Netherlands) and Ciba (Basel, Switzerland)—began full-scale steroid research and development programs in the 1930s.

I know the experiment didn’t simply bring me back to my pre-August levels because of the fact that when I learned that the original test I took can sometimes overestimate your T levels, I took a more accurate test around four months after the start of the experiment (I’ve continued the lifestyle changes made during the experiment) and my total T had gone up again to 826.9 ng/dL.
I was depressed, getting fat, and zero libido. My doc did a full blood work up. My Total Testosterone level was 289 ng/dl. He offered TRT but I declined because I knew, at 53, that if I went on TRT my own testosterone production would shut down and at my age I would have a pretty difficult time kick starting it up again. I researched and researched for about a month. I started on Vitamin D 10,000 iu per day ( I knew this was a safe amount because I tested at 26ng/dl and optimum level is anywhere between 40-80ng/dl. I also took 1,200 mg of magnesium, 9mg of Boron and Vitamin K Complex. Tested again 3 months later and blood work showed I was at 720.

The sexual hormone can encourage fair behavior. For the study, subjects took part in a behavioral experiment where the distribution of a real amount of money was decided. The rules allowed both fair and unfair offers. The negotiating partner could subsequently accept or decline the offer. The fairer the offer, the less probable a refusal by the negotiating partner. If no agreement was reached, neither party earned anything. Test subjects with an artificially enhanced testosterone level generally made better, fairer offers than those who received placebos, thus reducing the risk of a rejection of their offer to a minimum. Two later studies have empirically confirmed these results.[75][76][77] However men with high testosterone were significantly 27% less generous in an ultimatum game.[78] The Annual NY Academy of Sciences has also found anabolic steroid use which increase testosterone to be higher in teenagers, and this was associated with increased violence.[79] Studies have also found administered testosterone to increase verbal aggression and anger in some participants.[80]
Testosterone strengthens bones. You may have thought of osteoporosis as a health problem that only women have to worry about, but men can suffer from this bone-weakening disease too. And low testosterone levels may be to blame. Testosterone has been shown to play an important role in bone health. It increases bone density by stimulating bone mineralization as well as decreases bone resorption. Elderly men suffering from osteoporosis typically have sub-optimal testosterone levels. If you want to enjoy strong, healthy bones well into old age, take steps to improve your testosterone levels now.
Findings that improvements in serum glucose, serum insulin, insulin resistance or glycemic control, in men treated with testosterone are accompanied by reduced measures of central obesity, are in line with other studies showing a specific effect of testosterone in reducing central or visceral obesity (Rebuffe-Scrive et al 1991; Marin, Holmang et al 1992). Furthermore, studies that have shown neutral effects of testosterone on glucose metabolism have not measured (Corrales et al 2004), or shown neutral effects (Lee et al 2005) (Tripathy et al 1998; Bhasin et al 2005) on central obesity. Given the known association of visceral obesity with insulin resistance, it is possible that testosterone treatment of hypogonadal men acts to improve insulin resistance and diabetes through an effect in reducing central obesity. This effect can be explained by the action of testosterone in inhibiting lipoprotein lipase and thereby reducing triglyceride uptake into adipocytes (Sorva et al 1988), an action which seems to occur preferentially in visceral fat (Marin et al 1995; Marin et al 1996). Visceral fat is thought to be more responsive to hormonal changes due to a greater concentration of androgen receptors and increased vascularity compared with subcutaneous fat (Bjorntorp 1996). Further explanation of the links between hypogonadism and obesity is offered by the hypogonadal-obesity-adipocytokine cycle hypothesis (see Figure 1). In this model, increases in body fat lead to increases in aromatase levels, in addition to insulin resistance, adverse lipid profiles and increased leptin levels. Increased action of aromatase in metabolizing testosterone to estrogen, reduces testosterone levels which induces further accumulation of visceral fat. Higher leptin levels and possibly other factors, act at the pituitary to suppress gonadotrophin release and exacerbate hypogonadism (Cohen 1999; Kapoor et al 2005). Leptin has also been shown to reduce testosterone secretion from rodent testes in vitro (Tena-Sempere et al 1999). A full review of the relationship between testosterone, insulin resistance and diabetes can be found elsewhere (Kapoor et al 2005; Jones 2007).

Avoid stressful situations – It is actually that simple. If you can avoid stressful situations, then you can significantly improve your overall testosterone production. Why is that? Well, you should know that stress makes our bodies to produce cortisol that is a notorious and well-known testosterone killer. So, what can you do about it? Well, you should definitely try deep breathing, meditating, exercising, and other lifestyle changes that can help you deal with the stressful situations the right way.
Before we go any further, know that fenugreek is an herb of Asian origin, commonly used in Indian cuisine.  The Indians have been consuming it as an aphrodisiac and an herbal cure-all for centuries which might explain why that waiter in your local Indian restaurant is always smiling. As it turns out, there is actually some validity to the purported claims.

Men who take Testosterone report a surge in their sex drive and frequency of sex. They are better able to work out, build muscle mass and strength. The fat around their belly melts away as they lose weight and trim their waists. Men who enroll in a comprehensive Testosterone Replacement program which includes diet, nutrition and exercise - feel better, sleep better and look better. They have their edge back along with a restored enthusiasm for daily living, pursuing relationships and living life.
The chemical synthesis of testosterone from cholesterol was achieved in August that year by Butenandt and Hanisch.[187] Only a week later, the Ciba group in Zurich, Leopold Ruzicka (1887–1976) and A. Wettstein, published their synthesis of testosterone.[188] These independent partial syntheses of testosterone from a cholesterol base earned both Butenandt and Ruzicka the joint 1939 Nobel Prize in Chemistry.[186][189] Testosterone was identified as 17β-hydroxyandrost-4-en-3-one (C19H28O2), a solid polycyclic alcohol with a hydroxyl group at the 17th carbon atom. This also made it obvious that additional modifications on the synthesized testosterone could be made, i.e., esterification and alkylation.

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?
If your priority is to find and use a safe, effective, and natural testosterone booster, then you have every right to ask yourself do all of these hormone supplements work for real? Also, do they work at all? Are you going to waste your money or finally find an answer to your burning questions? Well, long story short, the testosterone supplements do their work just fine.
It also has vitamin B6. One study called out folate and vitamins B6 and B12 as important nutrients for athletes to achieve optimal health and performance. Vitamin B6 is commonly found in food, like fortified cereals, and as with magnesium, it’s possible to have too much vitamin B6. The NIH recommends an upper daily limit for adults of 100mg per day. Beast Sports comes well under this limit at 10mg per day, but still well above the minimum recommended dose of 1.7mg needed to see benefits.

By passing this bill, the Congress has amended the Controlled Substances Act to include Androstenedione supplements such as 4 Androstenediol, 5 Androstenediol, etc. The original Anabolic Steroid Control Act was passed in 1990 creating a list of anabolic steroids that would be classified as "Schedule III" substances and put in the same category as drugs such as heroin and cocaine. Now, with the passage of Senate Bill 2195 (the Anabolic Steroid Control Act of 2004), they have added Androstenedione supplements to the Controlled Substances Act.

Although some men believe that taking testosterone medications may help them feel younger and more vigorous as they age, few rigorous studies have examined testosterone therapy in men who have healthy testosterone levels. And some small studies have revealed mixed results. For example, in one study healthy men who took testosterone medications increased muscle mass but didn't gain strength.
