Documented Uses

• Preparation by microbial dehydrogenation of 17alpha-methyltestosterone.
• ... Reduction of 17alpha-methyltestosterone with selenium dioxide.
• Preparation: ... Wettstein et al, US 2900398 (1959 to Ciba).
• While data specific to methandrostenolone were not available(SRC, 2005), the literature suggests that some pharmaceutically active compounds originating from human and veterinary therapy are not eliminated completely in municipal sewage treatment plants and are therefore discharged into receiving waters(1). Wastewater treatment processes often were not designed to remove them from the effluent(2). Selected organic waste compounds may be degrading to new and more persistent compounds that may be released instead of
• Daily oral administration of anabolic steroid, methandienone, to mink improved fur quality.
• This is a controlled substance (anabolic steroid)... .
