Nandrolone Phenylpropionate/NPP Steroid Powder PurityPosted by freemexy on September 17th, 2019 Nandrolone Phenylpropionate/NPP Steroid Powder Purity > 99 % Durabolin, more commonly known among bodybuilders as Nandrolone Phenylpropionate(NPP) powder supplier, or just NPP, is a close relative of the popular steroid Deca Durabolin.Nandrolone Phenylpropionate (NPP) is the lesser known and less popular phenylpropionate ester version of nandrolone. First off its important to understand the difference between what we know as 'deca' and what we know as "NPP". To put it in simple terms the difference is simply the ester. On the basis of the hormone’s function, Nandrolone Phenylpropionate is identical to Nandrolone Decanoate. Both forms are comprised of the same active hormone. In the case of NPP we have a shorter ester version that gives a larger burst of Nandrolone after injection, but also carries a much shorter half-life. This means Nandrolone Phenylpropionate has to be injected more frequently than its larger ester counterpart if blood levels are to remain stable.androlone Phenylpropionate is also significantly less estrogenic than testosterone. Both Nandrolone and testosterone aromatize, but Nandrolone only does so at approximately 20% the rate of testosterone. Dosage and Cycling: Like it? Share it!More by this author |
