Methenolone acetate is an acetate ester of methenolone, a synthetic anabolic-androgenic steroid structurally related to dihydrotestosterone.

The oral acetate formulation is associated with the Primobolan designation and differs pharmacokinetically from injectable methenolone esters. Its historical pharmaceutical use has included selected catabolic and wasting conditions.

The supplied presentation specifies 25mg tablets. Like other anabolic-androgenic steroids, methenolone can influence endogenous hormone production, fertility, lipid metabolism, and androgen-sensitive tissues.
