Testosterone synthesis pathway

Testosterone is a hormone produced in the male testes. During a boy's pubescent years (ages 9 to 14), there is an increase in production that leads to male secondary sexual characteristics such as a deeper voice, more muscle mass, facial hair growth and enlargement of the Adam's apple (among others). Some teenage boys experience these puberty changes at later ages than others. The timing of puberty is often genetically determined (through heredity), but other factors can play a role in delaying it, such as poor nutrition, physical trauma and certain diseases. Stimulating testosterone production naturally is possible in teen boys, although in rare cases hormone therapy may be needed to trigger and complete puberty.

The original brand name of oxandrolone was Anavar, which was marketed in the United States and the Netherlands . [4] [33] This product was eventually discontinued and replaced in the United States with a new product named Oxandrin, which is the sole remaining brand name for oxandrolone in the United States. [4] [34] Oxandrolone has also been sold under the brand names Antitriol ( Spain ), Anatrophill ( France ), Lipidex ( Brazil ), Lonavar ( Argentina , Australia , Italy ), Protivar, and Vasorome ( Japan ) among others. [4] [27] [33] [35] Additional brand names exist for products that are manufactured for the steroid black market. [4]

For the off-season athlete there is no anabolic steroid more important or beneficial than testosterone. High levels of testosterone will promote significant increases in lean muscle mass and strength. This is assuming that the individual is consuming adequate calories. Compounds like Testosterone Propionate are not magical, you will still need to feed your body enough calories. During an off-season period of growth, this means total caloric intake will need to be slightly above maintenance. This will, unfortunately, promote body fat gain. However, the key to a successful off-season is gaining lean tissue while minimizing body fat gain to the fullest extent possible. By supplementing with Testosterone Propionate you will be able to achieve this more efficiently. High testosterone levels will promote a stronger metabolic rate. This is not a license to eat like there’s no end in sight, but you should be able to make better use of your calories.

While I was doing my research one thing I was worried about right from the beginning was side effects and how safe testosterone boosters really are. After thoroughly researching the most common ingredients and most of the test boosters that currently exist I am happy to report that there are a very few on the market that are unsafe. These supplements by their very nature use only natural ingredients and can’t cause any natural side effects. There are generally no synthetic ingredients in most of the products currently on the market. However, a quick word of warning, I would stay away from any product that uses a “proprietary blend” and does not disclose its full ingredients list along with the exact dosages of each ingredient. Which brings me to my next point…

In 209 community-dwelling men with low T levels (100 to 350 ng/dL [ to  nmol/L]) from Testosterone in Older Men (TOM) with Mobility Limitations Trial, the daily T gel therapy for 6 months improved both leg-press and chest-press strength and stair-climbing power [ 65 ]. Testosterone may also influence muscle metabolism by improving haemoglobin levels in older men with mild anaemia [ 66 , 67 ]. In women, skeletal muscle tissue seems to be sensitive to the anabolic action of androgens [ 68 ]. However, the impact of T administration on full physical function has not been fully studied. The precise molecular mechanisms underlying these observed physical changes in men are likely to include specific T effects on adipocytes and skeletal muscle cell receptors. The binding of T to its receptors could lead to the stimulation of lipolysis and protein synthesis [ 41 , 69 ]. Finally, several lines of evidence support the hypothesis of permissive effects of T on the differentiation of the precursor stromal cells into muscular line [ 70 ].
