    Estradiol propionate (EP), also known as estradiol monopropionate or estradiol 17β-propionate and sold under the brand names Acrofollin, Akrofollin, and Follhormon, is an estrogen medication and estrogen ester which is no longer marketed. It is the C17β propionate ester of estradiol. EP was provided in an oil solution and was administered by intramuscular injection. The medication was first marketed by 1938 or 1939.

    Footnotes: a = Relative binding affinities (RBAs) were determined via in-vitro displacement of labeled estradiol from estrogen receptors (ERs) generally of rodent uterine cytosol. Estrogen esters are variably hydrolyzed into estrogens in these systems (shorter ester chain length -> greater rate of hydrolysis) and the ER RBAs of the esters decrease strongly when hydrolysis is prevented. b = Relative estrogenic potencies (REPs) were calculated from half-maximal effective concentrations (EC50) that were determined via in-vitro β‐galactosidase (β-gal) and green fluorescent protein (GFP) production assays in yeast expressing human ERα and human ERβ. Both mammalian cells and yeast have the capacity to hydrolyze estrogen esters. c = The affinities of estradiol cypionate for the ERs are similar to those of estradiol valerate and estradiol benzoate (figure).
