Nandro-Phenyl By Sterling Knight

Nandrolone phenylpropionate (Durabolin) is a fast acting nandrolone with an active-life of 2-3 days as compared to Nandrolone Decanoate's 14-16 day active-life. For this reason, males injected Nandrolone phenylpropionate every 2-3 days and women reportedly avoided virilization effects with injections every 5-7 days (while still enjoying a very high quality but slow lean mass gain). For more rapid strength and mass gains, Nandrolone Decanoate was noted as a better choice of nandrolone.

Post-cycle retention of lean muscle mass gains were somewhat better with Nandrolone phenylpropionate however. This was mostly due to the fact that most individuals used lower dosages of Nandrolone phenylpropionate and therefore experience less HPTA suppression. Nandrolone phenylpropionate is highly anabolic, which means a quick build-up of proteins stored intracellularly in muscle tissue, and a positive nitrogen balance. For this reason, as with all nandrolones, a high protein diet was a must. Since Nandrolone phenylpropionate caused much less water retention than Nandrolone decanoate (again due to lower dosages), it was an excellent addition to pre-contest stacks. Also due to a shorter active-life, Nandrolone phenylpropionate appears to aromatize less than Deca.

Nandrolone phenylpropionate has no reported negative effect on the liver but will decrease natural androgen production in higher long-term dosages. Durbolin was considered the safest AAS. I have utilized Nandrolone phenylpropionate's fast acting highly anabolic qualities as part of a site-injection protocol (stacked with Testosterone propionate and Methenolone Enanthate ) with great results.
