Drostanolone propionate is a prodrug of drostanolone. Like other AAS, drostanolone is an agonist of the androgen receptor (AR). It is not a substrate for 5α-reductase and is a poor substrate for 3α-hydroxysteroid dehydrogenase (3α-HSD), and therefore shows a high ratio of anabolic to androgenic activity. As a DHT derivative, drostanolone is not a substrate for aromatase and hence cannot be aromatized into estrogenic metabolites. While no data are available on the progestogenic activity of drostanolone, it is thought to have low or no such activity similarly to other DHT derivatives. Since the drug is not 17α-alkylated, it is not known to cause hepatotoxicity.

Drostanolone propionate is not active via the oral route and must be administered via intramuscular injection. The elimination half-life of the drug via this route is approximately 2 days. It has a much longer elimination half-life via intramuscular injection than drostanolone. Drostanolone propionate is metabolized into drostanolone, which is the active form.
