Dianabol 

Methandrostenolone is a 17-alpha-alkylated oral anabolic-androgenic steroid with anabolic properties that are more pronounced than its androgenic effects. It has little progestational activity and easily converts to estrogens. Methandrostenolone has an anabolic activity index 0.60 and an androgenic activity index 0.20. Methandrostenolone has an extra double bond in the A-ring and, therefore, is not converted by 5-alpha reduction into DHT. Since methandrostenolone was created in the  1960s, it has been used for many different applications.

At present, the only legitimate therapeutic indications for this anabolic steroid are: replacement of male sex steroids in men who have androgen deficiency, for example as a result of loss of both testes; the treatment of certain rare forms of aplastic anemia which are or may be responsive to anabolic androgens; and, in certain countries, to counteract catabolic states, for example after major trauma.
