Description
Drostanolone Propionate , also known as Masterone, is an anabolic steroid derived from dihydrotestosterone (DHT) characterized by a high androgenic effect and moderate anabolic effects. It does not aromatize in the body, acting as a mild aromatase inhibitor, and prevents its conversion to estradiol.

Due to its affinity for androgen receptors in the muscles, prostate, and scalp, Drostanolone Propionate can cause androgenic side effects such as hair loss, prostate enlargement, and increased body hair growth. However, its antiestrogenic properties make it ideal for athletes and bodybuilders during cutting phases, helping them maintain strength and motivation even on low-carb diets.

In bodybuilding, Drostanolone Propionate (Masteron) is valued for promoting muscle definition without water retention. Its mild diuretic effect and fat-burning properties help reduce body fat by up to 5–10%, resulting in lean, sculpted muscles.
