Weak Anabolic Steroid used often by Germans during their Olympic glory days. Version of testosterone that is chlorinated so as to prevent converstion to DHT while also rendering the chemical incapable of concersion 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.
