What is "mesterolone"

n. An androgen.

Mesterolone is an orally applicable androgen and dihydrotestosterone (DHT) derivative. 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 rarely used for replacement therapies.
