What is Metenolone?

Metenolone is a DHT-derived steroid with comparatively weak androgenic activity. It was sold as the acetate (tablets) and the enanthate (depot injection). It is not converted to oestrogen.

How well studied is Metenolone?

Formerly used for aplastic anaemia, among other things; clinical data are old and limited. For misuse in sport there are mainly doping statistics, hardly any studies.

What side effects and risks does Metenolone have?

In women, virilisation (irreversible voice deepening, menstrual disturbances, facial hair). In men, suppressed sperm production and prostate enlargement; in adolescents premature closure of growth plates. Plus the general androgen risks for blood lipids and the cardiovascular system.

Is Metenolone approved in Germany?

In short: no – only outside the EU. Formerly marketed in Germany by Schering, now no longer available. One of the most frequently misused doping agents; 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.
