Nandrolone phenylpropionate ( NPP ), or nandrolone phenpropionate , sold under the brand name Durabolin amomg others, is a synthetic androgen and anabolic steroid and a nandrolone ester .     It is marketed in many countries throughout the world, including in the United Kingdom and Canada , and along with nandrolone decanoate (Deca-Durabolin), is one of the most widely used esters of nandrolone .   Nandrolone esters like NPP and nandrolone decanoate are prodrugs of nandrolone. 
Many athletes, ball players, fighters, and any athlete who could benefit from the therapeutic relief often supplement with Deca Durabolin. Such individuals commonly have no desire to build any new lean muscle mass, but the relief alone is invaluable. Further, such relief can be obtained by a very low dose. A slightly higher dose will provide relief, greatly enhance overall recovery, and enhance muscular endurance. When it comes to performance enhancement, most athletes will find this steroid is hard to beat. More importantly, the relief effects of Deca Durabolin are not masking or false; this anabolic steroid shares nothing in common with over the counter painkillers or prescription painkillers like opiates. Such painkillers only mask the pain, whereas Deca Durabolin can actually heal the body.
