Overview
Nandrolone Phenylpropionate (NPP) is an anabolic androgenic steroid (AAS) that is a synthetic derivative of testosterone. It is a shorter-acting ester variant of nandrolone, distinguishing it from nandrolone decanoate (Deca-Durabolin) which has a much longer half-life. Originally developed for medical applications, like other anabolic steroids, NPP has also been used non-medically, particularly in athletic and bodybuilding communities, for its anabolic effects. It is a controlled substance in many regions due to its potential for misuse and adverse effects. As a prescription medication, its use is directed by a licensed clinician for specific medical conditions.
