Usage: Nandrolone phenylpropionate is one of the most popular injectable steroids. It is basically Deca, with a shorter ester (phenylpropionate instead of decanoate ester found in deca durabolin or nandrolone decanoate), resulting in quicker release into the bloodstream. Although its shorter ester means it will require more frequent injections than decanoate, the positive side is that the amount of effective nandrolone in the blood and its levels are more easilly contollable. It's popularity is likely due to the fact that nandrolone exhibits significant anabolic effects with minimal androgenic side effects.

2, Applications of Nandrolone Phenylpropionate:

Nandrolone phenylpropionate (NPP) (brand name Durabolin, Fenobolin, numerous others), or nandrolone phenpropionate, also known as nandrolone hydrocinnamate, as well as 19-nortestosterone 17β-phenylpropionate or 17β-(1-oxo-3-phenylpropoxy)estr-4-en-3-one, is a synthetic androgen and anabolic steroid and a nandrolone ester. It was introduced in 1959. NPP is marketed in many countries throughout the world, including in the United Kingdom and Canada, and along with nandrolone decanoate, is one of the most widely used nandrolone esters. Both NPP and nandrolone decanoate are prodrugs of nandrolone.

Nandrolone Phenylpropionate, or NPP, is considered to be the best alternative to Deca Durabolin in terms of benefits. Nandrolone Phenylpropionate represents injectable anabolic steroid which characteristics are similar to nandrolone decanoate but is much faster acting compound. One of the biggest advantages of using NPP is that it is more effective, potent, and affordable than Deca Durabolin. Moreover, use of Nandrolone Phenylpropionate does not lead to formation of excess estrogens, which means that it can be used even by steroid users who have a history of estrogenic side effects (oily skin, acne, etc.) after using anabolic steroids and performance enhancing drugs.

NPP Dosage and Cycling
For beginners a dosage of 100mg EOD (every other day) is a good start and more more advanced users who have used Deca a few times at larger dosages usually take between 150 to 200mg EOD or even more which I would not advise. Cycle length usually lasts between 8 and 12 weeks.

NPP can be used in both cutting or bulking cycles. Many people refer to it as a mild version of Trenbolone. For bulking cycles its usually taken along with Testosterone Enanthate or Cypionate and an oral Steroid such as Dianabol. For cutting cycles people often take it alongside Testosterone Propionate and Winstrol and quite often with a fat burner such as Clenbuterol.
