Nandrolone Phenylpropionate is an anabolic steroid that is very similar to the popular Nandrolone Decanoate compound. However, Nandrolone Phenylpropionate was the first Nandrolone compound ever commercially sold. Nandrolone Phenylpropionate hit the shelves in the 1950’s and was brought to the market by Organon under the name Durabolin. Soon after Organon would release its Decanoate cousin under the name Deca Durabolin.

Nandrolone Phenylpropionate is a small ester base anabolic steroid and is commonly referred to as NPP. This product has never been as popular as the larger ester Decanoate version, in part due to availability; however, in the modern era it has begun to see a resurgence in both use and availability thanks in part due to underground labs.
