Where this one sits
NPP is where most of the confusion in this family lives, because the abbreviation hides what it is. NPP and Deca are both nandrolone; the letters stand for the phenylpropionate ester and nothing more. There is also an untouched language opportunity here: nandrolone phenylpropionate bestellen and nandrolone phenylpropionate kaufen both draw steady interest at positions 78 and 87, with no page in the estate written for either.
Why this one
NPP and Deca are the same nandrolone. The phenylpropionate ester is the short one, so the compound appears and clears quickly. Searches for nandrolone phenylpropionate in Dutch and German sit at position 78 to 87, effectively unanswered.

Common questions
What is the difference between NPP and Deca?
The ester only. Both are nandrolone. NPP is the phenylpropionate ester on a roughly 1.5 day curve; Deca is the decanoate ester at roughly 7.5 days.
Is NPP the same as nandrolone phenylpropionate?
Yes. NPP is simply the abbreviation. It is supplied here at 150 mg/ml.
Why is NPP sometimes called the short Deca?
Because both are nandrolone and the only difference is the ester. Calling NPP a short Deca is loose but not wrong: it is the same compound on a roughly 1.5 day curve instead of a 7.5 day one.
How is NPP (Nandrolone Phenylpropionate) stored?
Room temperature, protected from light.
Does this page give dosing information?
No. This page covers the ester, the concentration, measured content and storage only. It does not provide dosing protocols, cycle design or administration schedules.
