Nandrolone Phenylpropionate (Nandrolone Phenylpropionate (NPP))
A shorter-ester version of nandrolone (NPP) that acts faster and clears sooner than Deca-Durabolin, offering the same anabolic profile with more responsive blood levels. Educational reference only.
How it works
Same active hormone as Deca (nandrolone) but with a shorter phenylpropionate ester, giving quicker onset and faster clearance. Acts on androgen receptors with high anabolic and reduced androgenic activity.
Key facts
- Molecular weight: 406.6 Da
- Half-life: ~2.5-4.5 days
- Bioavailability: Intramuscular injection
- Storage: Room temperature; protect from light.
Dosing overview
- Typical dose: Variable; more frequent than Deca
- Frequency: Every 2-3 days
- Duration: Cycled
- Route: Intramuscular injection
Protocol notes
- Shorter ester requires more frequent injections than decanoate.
- Preferred when faster onset/offset is desired.
- Usually combined with testosterone in non-medical use.
Reported benefits
- Lean mass gains
- Faster onset than Deca
- Faster clearance (flexibility)
- Reputed joint comfort
Possible side effects
- Testosterone suppression
- Sexual dysfunction
- Progestogenic effects
- More frequent injections
- Adverse lipids
Research
- Ester length and nandrolone kinetics (2016): Phenylpropionate ester gave faster peaks and clearance than decanoate in pharmacokinetic comparisons.
