Mast P (Drostanolone Propionate), commonly known as Masteron, is an injectable anabolic-androgenic steroid (AAS) derived from dihydrotestosterone (DHT). Primarily used in bodybuilding for cutting cycles, it acts as an anti-estrogen, helping to reduce water retention, enhance muscle hardness, and improve definition without promoting significant mass gains.
Key Details About Mast P (Drostanolone Propionate):
Function: It is a DHT derivative, meaning it does not aromatize (convert to estrogen) and acts as an aromatase inhibitor.

Administration: It is an injectable steroid with a fast-acting propionate ester.
Side Effects: As an androgen, it can cause hair loss, acne, prostate enlargement, and virilization in women.
