No clinical studies. The evidence consists of case reports of liver damage and regulatory warnings.

Is Methasterone approved in Germany?
In short: no. Not approved as a medicine anywhere. It turns up in “supplements” as an undeclared ingredient. WADA S1 (explicitly listed). 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.
