Pharmacodynamics Nandrolone, the active form of NPP. NPP is a nandrolone ester, or a prodrug of nandrolone. As such, it is an androgen and anabolic steroid, or an agonist of the androgen receptor, the biological target of androgens like testosterone. Relative to testosterone, NPP has enhanced anabolic effects and reduced androgenic effects. In addition to its anabolic and androgenic activity, NPP has low estrogenic activity (via its metabolite estradiol) and moderate progestogenic activity. Like other AAS, NPP has antigonadotropic effects, which are due to both its androgenic and progestogenic activity. Pharmacokinetics NPP is converted into nandrolone in the body, which is the active form of the drug. It has an extended elimination half-life in the body when administered via intramuscular injection. Its duration of action is approximately one week and it is administered once every few days to once per week. The elimination half-life and duration of action of NPP are much shorter than those of nandrolone decanoate.
