Clostebol acetate is a mild anabolic steroid that exhibits low androgenic effects and moderate anabolic ones. It is primarily produced for use in cattle, however its use has been banned by numerous countries, although this is not due to any health related concerns that they drug produces in treated animals (1, 2). The results produced in treated livestock, as well as some research indicating the use of the drug being suitable for some therapeutic treatments in humans (3), has sparked some interest in strength athletes and bodybuilders about the compound.
