Testosterone was the first anabolic androgenic steroid to be discovered and synthetically reproduced. This was in the early 1930s. Since then, there is documentation of the history of steroids online. They were initially used therapeutically in both human medicine and veterinary medicine. In human beings, there research was based on their ability to increase muscle growth, increase appetite and induce the secondary male sexual characteristics.
Further research acknowledged that they could be used to increase muscular strength and bulk, lean mass and body weight when combined with high intensity exercises and a proper diet. In sports, their use led to their banning. This is because of their side effects but mostly because they gave their users an unfair added advantage over their counterparts.
Oral forms of methyltestosterone and injection forms of testosterone propionate were the first to be synthesized. They were rumored to be used by German soldiers to increase their stamina during war. The second anabolic androgenic steroid to be produced was Methandrostenolone, marketed as Dianabol by Ciba in the 1940s. It was approved by the FDA in 1958 and is one of the steroids that were at one point legal. It was however only approved for use in burn victims and the wasted elderly population. It was nonetheless used off-label, by bodybuilders and athletes and was banned as a result.
After this, various anabolic steroids were synthesized through alkylation and esterification. This allowed development of anabolic androgenic steroids that can be administered intramuscularly and subcutaneously. However, their legal status varies from country to country but all sports organizations have banned their use. In countries like the USA and Canada, they are controlled substances; this means that their use, sale and possession are illegal without a prescription.
Despite this, anabolic androgenic steroids are available in online markets and black markets for their off-label use.
