Appearance White to off-white crystalline powder Odorless or nearly odorless Practically insoluble in water Soluble in organic solvents (e.g., ethanol, acetone, oils) Drostanolone Propionate RAW (API) is a regulated steroid raw material with defined identity, purity, and quality attributes. Drostanolone propionate is a DHT-derived anabolic–androgenic steroid (AAS). The propionate ester only affects release rate; the active hormone is drostanolone. After administration in historical medical or research contexts, esterases cleave the propionate ester This releases free drostanolone into circulation The propionate ester provides a relatively short duration of action
