Clostebol, usually as the ester clostebol acetate, is a synthetic anabolic androgenic steroid. Clostebol is the 4-chloro derivative of the natural hormone testosterone. It is a weak anabolic Steroid used often by Germans during their Olympic glory days. Version of testosterone that is chlorinated so as to prevent conversion to DHT while also rendering the chemical incapable of conversion to estrogen. Although these are both desirable to body builders, the chemical never became popular in the US probably due to availability and the weak nature as compared with testosterone. (Source: Wikipedia)
