Active substance: Mesterolone

Mesterolone is a synthetic, orally active anabolic-androgenic steroid (AAS) and derivative of dihydrotestosterone (DHT). It is sold under the brand names Proviron (as Provironum in Asia-Pacific region) and Mestoranum, by Bayer Schering Pharma (earlier by Schering). In the late 1970s and early 1980s, it was used with some success in controlled studies of men suffering from various forms of depression. Mesterolone is a relatively weak androgen and is rarely used for replacement therapies.

Mesterolone had seen widespread use in bodybuilding primarily for antiestrogenic activity in anabolic steroid stacks but such use has declined after introduction of aromatase inhibitors and SERMs. Most significant benefits of current Mesterolone use are considered by bodybuilders to be maintaining libido off-cycle and also relatively and temporarily improving vascularity.
