Methyldrostanolone is a C-17 alpha alkylated steroid, originally developed by the American pharmaceutical company Syntex. This steroid is already active and does not require conversion. Methyldrostanolone is the 17aa version of the injectable steroid drostanolone (Masteron). This extra methylation makes this steroid about 3-4x more anabolic than Masteron, and slightly more anabolic than oxandrolone.
