The first thing that you should know is that this anabolic steroid has a lot of the same properties as the compound, Nandrolone Decanoate (Deca). This anabolic steroid has a small ester base and it’s known as NPP for short. This anabolic steroid offers a host of performance benefits and therapeutic benefits. Aside from testosterone, the hormone known as Nandrolone is the anabolic steroid which is most-prescribed by doctors. However, the Decanoate formula is the most commonly-prescribed form of Nandrolone (rather than Nandrolone Phenylproprionate).In terms of how Nandrolone Phenylpropionate functions, it’s just the same as Nandrolone Decanoate. Each one is made from the same hormone as the other. However, with NPP (Nandrolone Phenylpropionate), the half-life is shorter and the burst of Nandrolone is bigger, post-injection.
