Durabolin-NPP (Nandrolone Phenylpropionate) by Omega Labs
100 mg/ML
What Is Durabolin-NPP?
Durabolin-NPP is the brand name for Nandrolone Phenylpropionate, a fast-acting injectable anabolic steroid manufactured by Omega Labs. It is designed to promote lean muscle mass, enhance strength, and support recovery.
NPP is part of the nandrolone family, which includes the popular Deca Durabolin (Nandrolone Decanoate). While both share similar anabolic properties, NPP offers a shorter ester chain, resulting in faster absorption and shorter detection time in the bloodstream.
Overview of Nandrolone Phenylpropionate
Chemically known as 19-norandrost-4-en-3-one-17beta-ol, Nandrolone Phenylpropionate is a 19-nortestosterone derivative—meaning it lacks a carbon atom at the 19th position, which reduces androgenic side effects compared to testosterone.
This compound provides a balanced anabolic environment, promoting muscle hypertrophy without excessive water retention or estrogenic activity.

| Anabolic Rating | 125 |
| Androgenic Rating | 37 |
| Estrogenic Activity | Low |
| Progestational Activity | Moderate |
| Active Life | 4–5 days |

How Durabolin-NPP Works in the Body
Once injected, Nandrolone Phenylpropionate binds to the androgen receptors in muscle tissues. This interaction increases nitrogen retention, protein synthesis, and red blood cell production — all of which are essential for muscle growth and recovery.
Compared to testosterone, NPP offers a cleaner anabolic effect with fewer androgenic side effects like hair loss or acne.
Half-life: Around 5 days, meaning users often inject it every 3–5 days for stable blood levels.
Durabolin-NPP vs. Deca Durabolin
| Feature | NPP (Durabolin) | Deca Durabolin |
|---|---|---|
| Ester Type | Phenylpropionate (short) | Decanoate (long) |
| Onset of Action | Fast (1–2 days) | Slow (7–10 days) |
| Injection Frequency | Every 3–5 days | Every 7–10 days |
| Water Retention | Low | Moderate |
| Cycle Length | 6–10 weeks | 10–14 weeks |
NPP’s shorter ester makes it a better choice for users who prefer faster results and shorter cycles.
