Drostanolone Propionate

What is it?

Drostanolone Propionate is an injectable anabolic androgenic steroid (AAS) derived from dihydrotestosterone (DHT). Originally developed and approved under the brand name Masteron for medical use in treating breast cancer, it is now better known in bodybuilding circles for its powerful hardening effects on muscle mass. Drostanolone Propionate is especially valued during cutting cycles for its ability to improve muscle density, vascularity, and overall physique sharpness without causing water retention.

How it Works

Drostanolone Propionate binds to androgen receptors and exerts a strong anabolic and moderate androgenic effect. Because it is a DHT derivative, it does not aromatize into estrogen, eliminating the risk of estrogen-related side effects like gynecomastia and bloating. It promotes a dry, hard look by enhancing muscle density and assisting fat loss indirectly through its androgenic activity. The propionate ester ensures that the steroid releases quickly into the bloodstream, requiring more frequent injections but providing rapid results.

Other Names

  • Masteron Propionate

  • Masteron

  • Drostanolone P

  • Mast P

  • Drolban (older brand name)

  • Masteril (less common brand name)

Benefits

  • Extreme Muscle Hardness: Ideal for achieving a dry, chiseled look during cutting phases.

  • No Estrogenic Side Effects: No risk of water retention or gynecomastia.

  • Enhanced Fat Loss: Helps athletes achieve lower body fat percentages when combined with proper diet and training.

  • Improved Strength: Provides strength gains without significant weight gain.

  • Increased Vascularity: Promotes a very vascular appearance, especially when body fat is low.

  • Mild Nature: Lower risk of harsh side effects compared to stronger steroids, making it popular even for contest preparation.

Dosage/Cycle

  • Typical Dosage (Men): 300–500 mg per week (commonly split into injections every other day)

  • Typical Dosage (Women): 50–100 mg per week (with extreme caution due to risk of virilization)

  • Cycle Length: 6–10 weeks

  • Administration: Intramuscular injection, every other day or even daily due to the short half-life (~2 days).

  • Stacking: Often stacked with Winstrol, Anavar, Trenbolone, or Testosterone (in cutting cycles).

Example Cycle:

  • Weeks 1–10: Drostanolone Propionate 400 mg/week (split injections)

  • Weeks 1–10: Testosterone Propionate 400 mg/week

Side Effects

  • Androgenic Effects: Acne, oily skin, hair thinning/loss (especially in genetically predisposed individuals).

  • Suppression of Natural Testosterone: Requires proper post-cycle therapy (PCT).

  • Virilization in Women: Deep voice, clitoral enlargement, body hair growth.

  • Injection Site Pain: Due to the short ester (common with Propionate compounds).

  • Cholesterol Impact: May negatively affect HDL/LDL levels (common with DHT derivatives).

Conclusion

Drostanolone Propionate is a premier choice for bodybuilders aiming for maximum muscle definition, hardness, and dryness. It shines brightest when body fat is already low, making it a staple during pre-competition phases. Its non-aromatizing nature and relatively mild side-effect profile make it a favorite for both professional athletes and serious enthusiasts — provided it's used responsibly with proper support and cycle planning.
