Nandrolone phenylpropionate

Nandrolone phenylpropionate (NPP), or nandrolone phenpropionate, is a synthetic anabolic-androgenic steroid (AAS) and the 1(2)-phenylpropionate ester of nandrolone. It was first introduced in 1957 and is marketed in many countries, including in the United States, Europe, and elsewhere worldwide.

Pharmacology

Nandrolone phenylpropionate is a prodrug of nandrolone. Like nandrolone, it has strong anabolic effects and weak androgenic effects, which give it a mild side effect profile and make it especially suitable for use in women and children. Nandrolone esters are used in the treatment of anemias, cachexia (wasting syndrome), osteoporosis, breast cancer, and for other indications.

Chemistry

Nandrolone phenylpropionate, or nandrolone 17β-phenylpropionate, is a synthetic estrane steroid and a derivative of testosterone. It is an androgen ester; specifically, it is the C17β phenylpropionate ester of nandrolone (19-nortestosterone).

Society and culture

Nandrolone phenylpropionate was introduced for medical use in 1957. It was the first nandrolone ester to be introduced, followed by nandrolone decanoate in 1962, and has been one of the most widely used nandrolone esters.
