Best-Effort Research Profile

Drostanolone is a synthetic steroid structurally related to dihydrotestosterone. Authoritative chemical databases classify it as a 3-oxo-5alpha-steroid, 17beta-hydroxy steroid, and anabolic androgenic steroid. The compound is distinct from drostanolone propionate, which is its 17beta-propionate ester.

Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.

Registry Identifiers

CAS RN: 58-19-5; PubChem CID: 6011; ChEBI: CHEBI:34838; EPA DSSTox: DTXSID6022971; molecular formula: C20H32O2; molecular weight: 304.47 g/mol; IUPAC name: 17-hydroxy-2-methyl-5alpha-androstan-3-one.

Source-Backed Observations

Drostanolone and drostanolone propionate are separate chemical entities. Much of the historical pharmaceutical and analytical literature concerns drostanolone propionate rather than the non-esterified compound. Drostanolone is listed by WHO within androgen and cytostatic sex-hormone nomenclature categories.
