Description:
Nandrolone Phenylpropionate, also known as “NPP” is very similar to the very popular steroid “Deca” which is Nandrolone with a longer ester (Decanoate). Nandrolone Phenylpropionate is, therefore, a shorter acting “Deca” for all practical intents and purposes. Anecdotally, it seems to produce less water retention than its longer acting cousin, and this would be very consistent with injectable testosterones, where we find that shorter esters provide much less water retention.
Nandrolone is one of the few steroids which has been used successfully in AIDS patients to stimulate weight gain , and although athletes using NPP in lieu of Deca find it to produce slightly less weight gain, this is probably a result of gaining less water weight. Nandrolone Phenylpropionate, is a more popular drug than Deca for use in cutting cycles recently, due to this fact
Applications:
Use after surgery for chronic wasting disease, serious illness, and weak thin, infirm, osteoporosis, infantile dysplasia, aplastic anemia, etc.
In earlier years, the only pharmaceutical injectables that were both widely available to bodybuilders and economical. Estrogen control did not then exist. For this reason, Durabolin’s low aromatizing properties were then quite useful. Durabolin therefore won wide popularity.
Cycle and Usage
Nandrolone Phenylpropionate makes a great stack with other short esters in an under 10 week cycle. A good cycle for bulking would be the classic NPP and test prop cycle. NPP at 300mg per week for 10 weeks, test prop at 300mg per week for 10 weeks. Notice I did not include an oral to kickstart the cycle as its not necessary with these short acting esters. Don’t forget also to use an aromatase inhibitor (AI).
