Testosterone(58-22-0)

Pharmacological effect: testosterone was first extracted from a male cow in 1935. After many years, it has developed a variety of different kinds of medicine. At present, testosterone in North America can be injected (such as testosterone cyclopentanoic acid and testosterone heptanoate), oral, buccal and skin permeable bags, creams and gel. The initial use of testosterone is to treat hypogonadism, that is, to supplement the symptoms of insufficient self-secretion or no natural secretion of testosterone. Proper use of testosterone under hormone replacement therapy (HRT) can maintain the level of testosterone in the blood at a normal level. Like other hormones, testosterone and other anabolic hormones have other uses in addition to supplement due to lack, but relatively have more side effects. Such as infertility, loss of sexual desire (sexual coldness) or impotence, osteoporosis, etc. In the late 1940s, testosterone was used as a commercial gimmick for anti-aging drugs, the same as growth hormone in modern times. Taking advantage of the masculinization of testosterone, transgender men (that is, women become men through transgender) will use testosterone as a substitute to maintain the testosterone level of normal men. Similarly, transgender women will use drugs to inhibit the production of testosterone to make estrogen work.
