Nandrolone Phenylpropionate (NPP) is the lesser known and less popular phenylpropionate ester version of Nandrolone. First off its important to understand the difference between what we know as ‘deca’ and what we know as “NPP”. To put it in simple terms the difference is simply the ester. NPP has the shorter ester while Decabol version of Nandrolone has the longer ‘deca’ ester. Many lifters have no clue they can use the compound they love so much in a shorter ester. The only disadvantage would be the amount of injections, the shorter ester would have to be injected every other day or every 3 days at the most, while the long ‘deca’ ester can be injected once or twice a week. However the advantages are there which I will discuss as we go along. The main reason Nandrolone Phenylpropionate never became as popular as the deca ester is because of the availability and the small amount of amount per ml in the pharm grade version. Decabol meanwhile came in 200mg per ml so really guys found it much easier to inject 200mg twice a week using just 1ml per injection. Now with the growth of underground labs this issue has disappeared and now you can get NPP in all kinds of mg/ml ratios.
