Pharmacodynamics<unk>  is an AAS, with both androgenic and anabolic effects. It is very similar in its effects to androstanolone (dihydrotestosterone; DHT), and can be thought of as an orally active version of this AAS. Due to inactivation by 3α-hydroxysteroid dehydrogenase (3α-HSD) in skeletal muscle,<unk>  is described as a very poor anabolic agent, similarly to androstanolone and mesterolone. As<unk>  is 5α-reduced, it cannot be aromatized and hence has no propensity for estrogenic side effects such as gynecomastia. The drug also has no progestogenic activity. Like other 17α-alkylated AAS,<unk>  is hepatotoxic. Pharmacokinetics Due to its C17α methyl group, unlike androstanolone,<unk>  is orally active.
