Dihydrotestosterone (DHT) (referred to as androstanolone or stanolone when used medically) can also be used in place of testosterone as an androgen. The availability of DHT is limited; it is not available in the United States or Canada, for instance, but it is available in certain European countries, including the United Kingdom , France , Spain , Belgium , Italy , and Luxembourg .  DHT is available in formulations including topical gel, buccal or sublingual tablets, and as esters in oil for intramuscular injection.  Relative to testosterone, and similarly to many synthetic AAS, DHT has the potential advantages of not being locally potentiated in so-called androgenic tissues that express 5α-reductase (as DHT is already 5α-reduced) and of not being aromatized into an estrogen (it is not a substrate for aromatase).
Oxymetholone is a man-made male hormone used to treat a low red blood cell count (anemia). It works by increasing the amount of the hormone involved in the production of red blood cells. Due to the possibility of serious, life-threatening side effects, this medication must not be used to improve athletic performance or physical appearance. Oxymetholone does not improve athletic ability. When used as directed under medical supervision, the risks are minimal. Use this drug for a condition only if it has been prescribed by your health care professional. This medication may also be used to treat an allergic swelling condition.
