Pharmacodynamics Norethandrolone (3-ketoethylestrenol), the active metabolite of<unk> . As an AAS,<unk>  is an agonist of the androgen receptor (AR), similarly to androgens like testosterone and dihydrotestosterone (DHT). It has low estrogenic activity (via aromatization into ethylestradiol following transformation into norethandrolone), strong progestogenic activity, and a high ratio of anabolic to androgenic activity, similarly to other nandrolone derivatives. Like other 17α-alkylated AAS,<unk>  has a risk of hepatotoxicity. Pharmacokinetics<unk>  has very low affinity for human serum sex hormone-binding globulin (SHBG), less than 5% of that of testosterone and less than 1% of that of DHT. It is known to be metabolized into the closely related AAS norethandrolone (17α-ethyl-19-nortestosterone) in the body and has been regarded as a prodrug of norethandrolone. This is in accordance with its very low affinity for the androgen receptor, only about 5% of that of testosterone and 2% of that of dihydrotestosterone.
