What is Nandrolone Phenylpropionate?
Nandrolone Phenylpropionate (NPP — short-acting 19-nor anabolic-androgenic steroid (injectable)) is the phenylpropionate ester of nandrolone — C₂₇H₃₄O₃, MW 406.6. Shorter-acting ester than nandrolone decanoate (peak ~1–2 days, active ~5–7 days), providing faster onset and shorter activity window. 19-nor testosterone derivative with high anabolic/low androgenic ratio. Activates progesterone receptor. Partially aromatises at ~20% of testosterone rate.
