The legal status of AAS varies from country to country: some have stricter controls on their use or prescription than others though in many countries they are not illegal. In the U.S., AAS are currently listed as Schedule III controlled substances under the Controlled Substances Act, which makes simple possession of such substances without a prescription a federal crime punishable by up to one year in prison for the first offense. Unlawful distribution or possession with intent to distribute AAS as a first offense is punished by up to ten years in prison. [206] In Canada, AAS and their derivatives are part of the Controlled Drugs and Substances Act and are Schedule IV substances, meaning that it is illegal to obtain or sell them without a prescription; however, possession is not punishable, a consequence reserved for schedule I, II, or III substances. Those guilty of buying or selling AAS in Canada can be imprisoned for up to 18 months. [207] Import and export also carry similar penalties. Prevention or treatment of osteoporosis in postmenopausal women. [18] [19] Nandrolone decanoate is approved for this use. [20] Although they have been indicated for this indication, AAS saw very little use for this purpose due to their virilizing side effects. [18] [21]Stimulation of lean body mass and prevention of bone loss in elderly men, as some studies indicate. [14] [15] [16] However, a 2006 placebo-controlled trial of low-dose testosterone supplementation in elderly men with low levels of testosterone found no benefit on body composition, physical performance, insulin sensitivity, or quality of life.

"Metastatic breast cancer: preliminary results with oral hormonal therapy". Semin. Oncol. 12 (4 Suppl 6): 61–4. PMID 3909420. Testosterone can be robustly converted by 5α-reductase into DHT in so-called androgenic tissues such as skin, scalp, prostate, and seminal vesicles, but not in muscle or bone, where 5α-reductase either is not expressed or is only minimally expressed. [72] As DHT is 3- to 10-fold more potent as an agonist of the AR than is testosterone, the AR agonist activity of testosterone is thus markedly and selectively potentiated in such tissues. [72] In contrast to testosterone, DHT and other 4,5α-dihydrogenated AAS are already 5α-reduced, and for this reason, cannot be potentiated in androgenic tissues. [72] 19-Nortestosterone derivatives like nandrolone can be metabolized by 5α-reductase similarly to testosterone, but 5α-reduced metabolites of 19-nortestosterone derivatives (e.g., 5α-dihydronandrolone) tend to have reduced activity as AR agonists, resulting in reduced androgenic activity in tissues that express 5α-reductase. [72] In addition, some 19-nortestosterone derivatives, including trestolone (7α-methyl-19-nortestosterone (MENT)), 11β-methyl-19-nortestosterone (11β-MNT), and dimethandrolone (7α,11β-dimethyl-19-nortestosterone), cannot be 5α-reduced. [166] Conversely, certain 17α-alkylated AAS like methyltestosterone are 5α-reduced and potentiated in androgenic tissues similarly to testosterone. [72] [67] 17α-Alkylated DHT derivatives cannot be potentiated via 5α-reductase however, as they are already 4,5α-reduced. [72] [67] De Naeyer H, et al. (2010).

The kidney damage in the bodybuilders has similarities to that seen in morbidly obese patients, but appears to be even more severe.

When doctors prescribe steroid medication, they always advise coming off the medication slowly by gradually reducing the dose. AAS, alone and in combination with progestogens, have been studied as potential male hormonal contraceptives. [48] Dual AAS and progestins such as trestolone and dimethandrolone undecanoate have also been studied as male contraceptives, with the latter under active investigation as of 2018. [235] [173] [236] Anabolic steroids are addictive. This means you can crave the drug, require more to get the same effect, and have withdrawal symptoms if you suddenly stop taking it. The development of muscle-building properties of testosterone was pursued in the 1940s, in the Soviet Union and in Eastern Bloc countries such as East Germany, where steroid programs were used to enhance the performance of Olympic and other amateur weight lifters. In response to the success of Russian weightlifters, the U.S. Olympic Team physician John Ziegler worked with synthetic chemists to develop an AAS with reduced androgenic effects. [197] Ziegler's work resulted in the production of methandrostenolone, which Ciba Pharmaceuticals marketed as Dianabol. The new steroid was approved for use in the U.S. by the Food and Drug Administration (FDA) in 1958. It was most commonly administered to burn victims and the elderly. The drug's off-label users were mostly bodybuilders and weight lifters. Although Ziegler prescribed only small doses to athletes, he soon discovered that those having used Dianabol developed enlarged prostates and atrophied testes. [198] AAS were placed on the list of banned substances of the International Olympic Committee (IOC) in 1976, and a decade later the committee introduced 'out-of-competition' doping tests because many athletes used AAS in their training period rather than during competition.
