Drostanolone Propionate (Masteron) is a synthetic androgenic anabolic steroid and is approximately 5 times as potent as natural methyltestosterone. Like testosterone and other androgenic hormones, drostanolone binds to the androgen receptor. It produces retention of nitrogen, potassium, and phosphorus; increases protein anabolism; and decreases amino acid catabolism. The antitumour activity of drostanolone appears related to reduction or competitive inhibition of prolactin receptors or estrogen receptors or production. Drostanolone Propionate (Masteron) can increase muscle mass and cause a positive nitrogen balance. The body mass is increased gradually over a period of 4-6 weeks.
