Masteron Propionate
What it does:
Masteron Propionate (Drostanolone Propionate) is a fast-acting DHT-derived anabolic steroid known for its ability to increase lean muscle mass, strength, and muscle definition without promoting water retention. It also exhibits anti-estrogenic properties, making it especially effective during cutting cycles or contest preparation. It helps enhance muscular hardness and density while supporting fat loss.
Normal Applications:
Originally used in the treatment of breast cancer, Masteron Propionate is now primarily utilized by athletes and bodybuilders for physique refinement. Its mild anabolic and strong androgenic profile make it ideal for pre-contest conditioning or during leaning phases when muscle definition is a priority. It is often combined with other non-aromatizing compounds.

Common Side Effects:
Since it is derived from DHT, Masteron Propionate does not convert to estrogen and thus avoids estrogen-related side effects like water retention and gynecomastia. However, users may experience androgenic effects such as oily skin, acne, increased facial/body hair, and hair loss. It also suppresses natural testosterone production.
Administration Recommendations & Ideal Dosages:
Common dosages range from 300–500 mg per week, typically split into injections every other day due to the short half-life. Cycles often last 6–10 weeks. Masteron Propionate is rarely used in bulking cycles but excels in cutting stacks with agents like Winstrol, Trenbolone, or Anavar. Post Cycle Therapy (PCT) is recommended after use.
