Crown Pharma Mast Prop 150mg

What is Mast Prop 150mg?

Mast Prop 150 (Masteron Propionate) is an injectable anabolic steroid produced by Crown Pharma (UK). Each 10 ml vial contains 150 mg of Drostanolone Propionate per ml. Its short-acting propionate ester offers rapid effects and easy control during cycles.

How Does Mast Prop 150mg Work?

Drostanolone Propionate is a derivative of DHT (dihydrotestosterone) with strong anti-estrogenic properties—it does not aromatize, eliminating the risk of water retention and gynecomastia. It binds effectively to androgen receptors, enhancing protein synthesis, nitrogen retention, and red blood cell production, all of which support lean muscle growth, fat loss, improved strength, and enhanced recovery.

Safety Considerations

While Mast Prop has a reputation for being a “mild steroid,” it’s still potent and requires careful dosing and monitoring:

• Side Effects: May include acne, oily skin, hair loss, and androgenic effects. Cardiovascular strain, hormone suppression, and cholesterol imbalance are also possible with systemic use.
• PCT Recommendations: A proper Post-Cycle Therapy is essential to restore natural testosterone levels after use.
