Nandrolone Phenylpropionate (Methandriol Dipropionate)


Nandrolone Phenylpropionate hit the shelves in the 1950’s and was brought to the market by Organon under the name Durabolin.


What is Nandrolone Phenylpropionate (NPP)?

Nandrolone Phenylpropionate (NPP) is an anabolic steroid that is very similar to the popular Nandrolone Decanoate (Deca Durabolin) compound. NPP is a small ester base anabolic steroid. Nandrolone Phenylpropionate carries with it numerous therapeutic and performance benefits. It is one of the most well tolerated steroids in both performance and medical settings. NPP has a shorter ester version that gives a larger burst of Nandrolone after injection, but also carries a much shorter half-life. This means Nandrolone Phenylpropionate must be injected more frequently than its larger ester counterpart if blood levels are to remain stable.

Nandrolone Phenylpropionate is slightly more anabolic than testosterone with a rating of 125 compared to testosterone’s rating of 100. It is also significantly less androgenic with a rating of 37 compared to testosterone’s rating of 100. Both Nandrolone and testosterone aromatize, but Nandrolone only does so at approximately 20% the rate of testosterone.
