Nandrolone Phenylpropionate (NPP)

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).

Nandrolone Phenylpropionate Functions & Traits

is a 19-nortestosterone (19-nor) anabolic androgenic steroid. The 19-nor classification refers to a structural change of the testosterone hormone in that the carbon atom has been removed at the 19^th position.

This simple structural change gives us Nandrolone, and by adding the short Phenylpropionate ester we have Nandrolone .

On the basis of the hormone’s function, Nandrolone  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  has to be injected more frequently than its larger ester counterpart if blood levels are to remain stable.

Nandrolone  is slightly more anabolic than testosterone with a rating of 125 compared to testosterone’s rating of 100.

It is also significantly less androgenic with a rating of 37 compared to testosterone’s rating of 100.

The reduced androgenicity is due to the Nandrolone hormone reducing to dihydronandrolone (DHN) instead of dihydrotestosterone (DHT).

This is one of the reasons this product  can be well tolerated at higher doses in some men than higher doses of testosterone.

This product  is also significantly less estrogenic than testosterone.

Both Nandrolone and testosterone aromatize, but Nandrolone only does so at approximately 20{13c175b4b24440b8a5165f6560f020b70106ae9a2c215c353f8f2fc99a8d1211} the rate of testosterone.
