What is Masteron Propionate (Drostanolone Propionate)?

Masteron Propionate (Drostanolone Propionate — short-acting DHT-derived AAS (injectable)) is the propionate ester of drostanolone — C₂₃H₃₆O₃, MW 360.5. Short-acting ester (peak ~1–2 days, active ~3 days). DHT-derived 2α-methyl modification provides aromatase inhibitory activity alongside androgenic effects. Does not aromatise. Acts as an anti-oestrogen by competitively inhibiting aromatase enzyme activity and binding to oestrogen receptors as a partial antagonist.
