What is Drostanolone?
Drostanolone is a steroid derived from dihydrotestosterone (DHT). It is not converted to oestrogen. It was formerly used for advanced breast cancer in postmenopausal women.
How well studied is Drostanolone?
Older, small clinical studies from breast cancer treatment; medically replaced by modern therapies. No reliable studies on use in strength sports.
What side effects and risks does Drostanolone have?
Typical androgen risks: falling HDL, higher blood pressure, cardiovascular strain, suppression of the hormone axis and fertility. As a DHT derivative it is strongly androgenic: acne, hair loss; virilisation in women (including a deeper voice, partly irreversible).
Is Drostanolone approved in Germany?
In short: no – only outside the EU. Formerly approved as a medicine (Masteron), now practically no longer marketed; no approved product known in Germany. WADA S1. Under Germany's Anti-Doping Act (AntiDopG), trading and supplying are prohibited, and even acquiring or possessing a “non-small quantity” (set by the Doping Substances Quantity Ordinance) is a criminal offence – including for recreational athletes and for personal use. Black-market products are frequently counterfeit, mislabelled or contaminated.
