NPP (Nandrolone Phenylpropionate) is a small ester base anabolic steroid. It is significantly less estrogenic than testosterone. Nandrolone aromatize at approximately 20% the rate of testosterone.
NPP is a 19-nortestosterone androgenic anabolic steroid. This type of steroid is made from Testosterone that has been modified at the 19th atom.
Athletes use low doses of Nandrolone Phenylpropionate (Methandriol Dipropionate) for the recovery and joint relief benefits. These are not masking benefits like painkillers provide but true relief.
NPP is observed to increase levels of IGF-1 (insulin-like growth factor). IGF-1 is a hormone that aids in recovery after training and plays a role in several types of cells.
