NPP 150 (Nandrolone phenylpropionate), also known under the brand name Durabolin is the active substance - nandrolone. Nandrolone phenylpropionate has a smaller half-life (4.2 days) than nandrolone decanoate or "deck" (7-10 days). This is why Nandrolone Phenylpropionate acts shorter than "Deca".
According to experienced athletes in the UK, the preparation causes significantly less water retention, and therefore it is more compatible with the "androgen" than nandrolone decanoate, although in theory it is dose-dependent and susceptibility because the active substance in phenylpropionate and decanoate one - nandrolone.
The ether chain phenylpropionate approximately two times shorter than the decanoate, whereby the active substance is rapidly absorbed into the bloodstream and has a shorter time of exposure. Therefore phenylpropionate has its advantages: 1 - a shorter period significantly reduces the incidence of side effects of nandrolone. 2 - in the event of side effects or poor tolerability course can be stopped and all the adverse reactions disappear quickly.
Phenylpropionate only drawback is the need for frequent injections, but it can not be called significant.
nandrolone metabolites excreted from the body for a long time. 16-18 months - phenylpropionate timing detection, and 18-24 months - decanoate. Therefore Nandrolone drugs are not recommended to receive competing athletes.
Side effects (UK)
NPP 150 are extremely rare and occur in very rare cases: the unreasonably high doses of the drug consumed and particularly sensitive to the substance of the people. On the function of the liver Nandrolone phenylpropionate it is not valid. The preparation has excellent portability and is safe in application.
