Masteron by LA Pharma S.R.L. is a pharmaceutical-grade injectable anabolic steroid containing Drostanolone Propionate at a concentration of 100mg/ml in a 10ml multi-dose vial (1,000mg total active compound). Celebrated across competitive sports and physique conditioning as an elite “finishing agent,” Masteron is specifically engineered for body recomposition, muscular density, and peak aesthetic definition.

Derived directly from Dihydrotestosterone (DHT), Drostanolone is completely incapable of converting into estrogen and exhibits natural anti-estrogenic properties. Formulated with LA Pharma’s clean carrier oil system, this fast-acting Propionate ester formulation draws out subcutaneous fluid, strips away soft water weight beneath the skin, and creates a granite-hard, dry, and highly vascular physique.

Key Benefits & Applications

Elite Muscle Density & Graininess: Pulls unwanted fluid out from between the skin and muscle bellies, eliminating subcutaneous bloat to deliver a dry, chiseled, and granite-hard muscular look.
Inherent Anti-Estrogenic Activity: Acts as a structural inhibitor against the aromatase enzyme, suppressing estrogenic signaling and reducing fluid retention when stacked with aromatizing compounds.
SHBG Suppression & Synergistic Potentiation: Binds with high affinity to Sex Hormone-Binding Globulin (SHBG), unbinding circulating testosterone and increasing the anabolic efficiency of co-administered agents.
Strength Preservation Under Caloric Deficits: Drives raw neuromuscular strength and power output without adding water weight, making it ideal for weight-class athletes and pre-contest cutting cycles.
Multi-Dose Vial Versatility: The 10ml rubber-stoppered vial allows for precise volume adjustments and micro-dosing flexibility needed for frequent short-ester injection schedules.
