NPP 125 is an injectable steroid containing 125 mgs per ML of the hormone nandrolone phenylpropionate.
NPP 125 is very fast acting and therefore makes it possible for the compound to be out of the body much more quickly. This makes this steroid a better choice than Deca for tested Bodybuilders and athletes. Users typically follow a dosage schedule of every other day when using this substance to keep blood levels elevated and stable.
Durabolin, as it is often called, is one of the most popular steroids being used amongst bodybuilders today. Durabolin is a low androgenic steroid with high anabolic effect. It will aromatize in high dosages, but not at the rate of testosterone. Bodybuilders using this substance by itself sometimes report a loss of libido, therefore, it is recommended that one run at least a small dose of testosterone or even a high androgen like Proviron to help prevent this issue.
