Low testosterone levels have a dramatic effect on emotional state. The American Academy of Family Physicians lists depression, impaired cognition and increased fatigue as symptoms of low testosterone production, or hypogonadism. Testosterone replacement therapy for hypogonadal men has successfully reduced negative moods relating to fatigue and depression while increasing feelings of self-esteem. Increasing testosterone in eugonadal men has also shown positive emotional benefits such as increased feelings of self-esteem and reduction of fatigue. The intensity of these benefits is dependent on dosage; a wide body of literature on testosterone increase has shown that at higher dosage aggression, and aggressive response, can become pronounced.
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.

Miscellaneous: Sleep: (REM sleep) increases nocturnal testosterone levels.[146] Behavior: Dominance challenges can, in some cases, stimulate increased testosterone release in men.[147] Drugs: Natural or man-made antiandrogens including spearmint tea reduce testosterone levels.[148][149][150] Licorice can decrease the production of testosterone and this effect is greater in females.[151]

A recent study compared total and bioavailable testosterone levels with inflammatory cytokines in men aged 65 and over. There was an inverse correlation with the pro-inflammatory soluble interleukin-6 receptor, but no association with interleukin-6 (IL-6), highly sensitive CRP (hsCRP), tumor necrosis factor-α (TNF-α) or interleukin-1β (IL-1β (Maggio et al 2006). Another trial found that young men with idiopathic hypogonadotrophic hypogonadism had higher levels of proinflammatory factors interleukin-2 (IL-2), interleukin-4 (IL-4), complement C3c and total immunoglobulin in comparison to controls (Yesilova et al 2000). Testosterone treatment in a group of hypogonadal men, mostly with known coronary artery disease, induced anti-inflammatory changes in the cytokine profile of reduced IL-1β and TNF-α and increased IL-10 (Malkin, Pugh, Jones et al 2004).

Testosterone is the primary sex hormone in men, and it is responsible for the development of many of the physical characteristics that are considered typically male. Women also produce the hormone in much smaller amounts. Testosterone, part of a hormone class known as androgens, is produced by the testicles after stimulation by the pituitary gland, which is located near the base of the brain, and it sends signals to a male's testicles (or to a woman's ovaries) that spark feelings of sexual desire.

Hi Douglas, this is a great question, thanks for reaching out. Apart from having a solid training plan that’s suited to your current level of fitness, and goals, you can also use a quality Testosterone Booster which could give you the lift you need to get back into the gym. If you find it difficult to swallow tablets, you can always empty the capsule into a glass of water, juice, or coffee to make it easier to take.
Two of the immediate metabolites of testosterone, 5α-DHT and estradiol, are biologically important and can be formed both in the liver and in extrahepatic tissues.[155] Approximately 5 to 7% of testosterone is converted by 5α-reductase into 5α-DHT, with circulating levels of 5α-DHT about 10% of those of testosterone, and approximately 0.3% of testosterone is converted into estradiol by aromatase.[2][155][161][162] 5α-Reductase is highly expressed in the male reproductive organs (including the prostate gland, seminal vesicles, and epididymides),[163] skin, hair follicles, and brain[164] and aromatase is highly expressed in adipose tissue, bone, and the brain.[165][166] As much as 90% of testosterone is converted into 5α-DHT in so-called androgenic tissues with high 5α-reductase expression,[156] and due to the several-fold greater potency of 5α-DHT as an AR agonist relative to testosterone,[167] it has been estimated that the effects of testosterone are potentiated 2- to 3-fold in such tissues.[168]
Intramuscular testosterone injections were first used around fifty years ago. Commercially available preparations contain testosterone esters in an oily vehicle. Esterification is designed to retard the release of testosterone from the depot site into the blood because the half life of unmodified testosterone would be very short. For many years intramuscular preparations were the most commonly used testosterone therapy and this is still the case in some centers. Pain can occur at injection sites, but the injections are generally well tolerated and free of major side effects. Until recently, the available intramuscular injections were designed for use at a frequency of between weekly and once every four weeks. These preparations are the cheapest mode of testosterone treatment available, but often cause supraphysiological testosterone levels in the days immediately following injection and/or low trough levels prior to the next injection during which time the symptoms of hypogonadism may return (Nieschlag et al 1976). More recently, a commercial preparation of testosterone undecanoate for intramuscular injection has become available. This has a much longer half life and produces testosterone levels in the physiological range throughout each treatment cycle (Schubert et al 2004). The usual dose frequency is once every three months. This is much more convenient for patients but does not allow prompt cessation of treatment if a contraindication to testosterone develops. The most common example of this would be prostate cancer and it has therefore been suggested that shorter acting testosterone preparations should preferably used for treating older patients (Nieschlag et al 2005). Similar considerations apply to the use of subcutaneous implants which take the form of cylindrical pellets injected under the skin of the abdominal wall and steadily release testosterone to provide physiological testosterone levels for up to six months. Problems also include pellet extrusion and infection (Handelsman et al 1997).

Hacking your testosterone influences everything from body composition to energy levels to mood. It’s easy to eat more butter; it’s hard to visit a doctor and get tested, but that’s what I recommend: know your levels. If you’re 25, you’ll know what your target is when you’re 35. By the time you’ve noticed symptoms of low testosterone, it’s too late to get your “normal” measurements!


If you are not making muscular gains by using your old BCAA supplement, our Advanced BCAA is the product to use to solve this problem.  Advanced BCAA’s are superior to free form BCAA’s because it is  more absorbable. Advanced BCAA is in peptide form and from predigested whey protein.  This makes it much more effective and beneficial to gaining muscle.  So if you have given up or don’t think BCAA’s work, try our Advanced BCAA powder and you wont be disappointed.

It also had a purpose. It turns out posing in powerful stances causes your testosterone to increase within 20 minutes [13,14]. In those two studies, power posing for just a few minutes also dropped cortisol and boosted confidence. It’s a great way to start your day, or to give yourself an edge before a job interview or a big presentation. They don’t call it “warrior pose” for nothing!
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.

These researchers took saliva samples from recreational women athletes before and after playing 10 minutes of flag football. The data showed that this short, intense burst of competitive sport triggered the immediate release of testosterone. Interestingly, the subjects' mental state also contributed to the data. Self-rated performance scores were directly related to testosterone levels.
Eggs often come up in reproductive health discussion. This time we’re talking about dietary eggs, as in omelets, and the role they play in boosting testosterone. The hormone boost from eggs comes primarily from the yolks, which are rich in dietary cholesterol, mono- and saturated fats—nutrients once demonized by health experts that have since proven to positively influence waistlines and hormone-health.
What are the side effects of testosterone pellets? Testosterone is the male sex hormone, and its levels in the body decline steadily with age. Many people wish to supplement it when they are deficient. Testosterone pellets can be a convenient form of testosterone replacement therapy, but they can cause side effects, such as fluid retention and acne. Learn more here. Read now
TT may help you but it may have adverse (harmful) results. (See discussion of these side effects below.) The Federal Drug Administration (FDA) has said that testosterone drug labels should state that there is a risk for heart disease and stroke for some men using testosterone products. All men should be checked for heart disease and stroke before, and periodically while on, TT. The AUA however, on careful review of evidence-based peer review literature, has stated that there is no strong evidence that TT either increases or decreases the risk of cardiovascular events.
Feeling low energy, lack of enthusiasm, but not so much on the sexual side, seems okay. At age 63 started an exercise program. nothing seem to help bring me back, so had my blood test at age 64. 150. 6 months later 165. My doctor started me on testosterone patches after a heart and prostate exam. Now two months into program, now using the gel, there seems little change. Disappointed. I am guess my next blood test will show less than 200. I am disappointed sufficiently to decide not to continue the program. I mean, the drugs cost $500 a month, although my cost is less. I guess my question is if I quit the program, will my body return to its normal, or will it be worse. i can live with a low normal, but less would not not be acceptable.
Over time, the testicular “machinery” that makes testosterone gradually becomes less effective, and testosterone levels start to fall, by about 1% a year, beginning in the 40s. As men get into their 50s, 60s, and beyond, they may start to have signs and symptoms of low testosterone such as lower sex drive and sense of vitality, erectile dysfunction, decreased energy, reduced muscle mass and bone density, and anemia. Taken together, these signs and symptoms are often called hypogonadism (“hypo” meaning low functioning and “gonadism” referring to the testicles). Researchers estimate that the condition affects anywhere from two to six million men in the United States. Yet it is an underdiagnosed problem, with only about 5% of those affected receiving treatment.
During the month before my experiment, I was definitely sleep deprived. Some nights I was only getting 4 to 5 hours. Testosterone killer! During my experiment I tried to get 8 to 9 hours of sleep at night as consistently as possible. I had to go to bed earlier, but I was only cutting into time that I would have been using to mindlessly surf the net anyway.

Testosterone is significantly correlated with aggression and competitive behaviour and is directly facilitated by the latter. There are two theories on the role of testosterone in aggression and competition.[81] The first one is the challenge hypothesis which states that testosterone would increase during puberty thus facilitating reproductive and competitive behaviour which would include aggression.[81] Thus it is the challenge of competition among males of the species that facilitates aggression and violence.[81] Studies conducted have found direct correlation between testosterone and dominance especially among the most violent criminals in prison who had the highest testosterone levels.[81] The same research also found fathers (those outside competitive environments) had the lowest testosterone levels compared to other males.[81]
Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T.[118] The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.
With ingredients like Fenugreek, Ashwagandha, Shilajit, and Boron Citrate, you can expect to see some increases in lean muscle mass thanks to the hike in free and total testosterone levels as well as its ability to suppress cortisol, a natural hormone that can reduce the body’s ability to use fat stores as energy. True GRIT Test Booster does not contain proprietary blends, so you can actually see the exact dosage you are getting from each ingredient listed.
Another effect that can limit treatment is polycythemia, which occurs due to various stimulatory effects of testosterone on erythropoiesis (Zitzmann and Nieschlag 2004). Polycythemia is known to produce increased rates of cerebral ischemia and there have been reports of stroke during testosterone induced polycythaemia (Krauss et al 1991). It is necessary to monitor hematocrit during testosterone treatment, and hematocrit greater than 50% should prompt either a reduction of dose if testosterone levels are high or high-normal, or cessation of treatment if levels are low-normal. On the other hand, late onset hypogonadism frequently results in anemia which will then normalize during physiological testosterone replacement.

I turned 50 and noticed I had low energy and no desire to workout. I decided to try a testosterone enhancer. I bought these and upon taking them I felt immediate results. I then ordered 3 more bottles on the spot. It is truly amazing how much of a difference it has made in my strength and endurance. Not to mention stamina. I never would've guessed that anything would have such a noticeable positive effect on strength and energy. I am so impressed.
Early infancy androgen effects are the least understood. In the first weeks of life for male infants, testosterone levels rise. The levels remain in a pubertal range for a few months, but usually reach the barely detectable levels of childhood by 4–7 months of age.[15][16] The function of this rise in humans is unknown. It has been theorized that brain masculinization is occurring since no significant changes have been identified in other parts of the body.[17] The male brain is masculinized by the aromatization of testosterone into estrogen, which crosses the blood–brain barrier and enters the male brain, whereas female fetuses have α-fetoprotein, which binds the estrogen so that female brains are not affected.[18]
I am 51 male. I have had low T for a few years now. I was using Testim for a few years, but I hated the smell and mostly feared getting thus stuff on the kids. The reason I stopped with all that nasty gel is because my T levels weren’t improving. So, why bother using anything that is not working, so I stopped. Apparently I am one of those men who do not absorb the gel very well. My T levels dropped from a low of around 200 on a 800+ scale to under 100 after I stopped using the gel.
Hello everyone. First off, thank you Dr. Abraham Morgentaler, for the excellent and refreshing article. I do not intend to spill my guts about symptoms or values on here as it has already been done so many times over. I will say that I am an RN BSN and have been on HRT for going on 6 yrs. I live in Oklahoma and when I first started noticing symptoms I knew something was wrong and began to do research myself. With an initial level of 241 no doctor here at that time, would even consider HRT as I was only 35ish at the time.

Tongkat ali (a.k.a. Longjack, a.k.a. Eurycoma Longifolia) is a foundational compound of Ayurveda, commonly used as an aphrodisiac. Similar to DHEA, longjack has been found to be effective in both men and women for improving libido, total and free testosterone concentrations as well as muscle mass and strength in men and women! And, unlike many of the other old world herbs commonly touted as natural testosterone boosters, longjack actually has a fair amount of human research denoting its benefits.

Testosterone is a sex hormone that plays important roles in the body. In men, it’s thought to regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm. A small amount of circulating testosterone is converted to estradiol, a form of estrogen. As men age, they often make less testosterone, and so they produce less estradiol as well. Thus, changes often attributed to testosterone deficiency might be partly or entirely due to the accompanying decline in estradiol.
