Masterone or drostanolone is an agonist of the androgen receptor. It is not a substrate for 5a-reductase and is a poor substrate for 3a-hydroxysteroid dehydrogenase, 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.
