Stealth Labs NPP 150 – Fast-Acting Nandrolone for Lean Mass & Recovery

Stealth Labs NPP 150 delivers 150 mg/mL of pharmaceutical-grade Nandrolone Phenylpropionate in a 10 mL vial. This short-acting ester version of Deca (Nandrolone Decanoate) provides rapid onset anabolic effects with fewer water retention issues and easier post-cycle recovery. Athletes looking for lean bulk gains, joint support, and muscle endurance will find NPP 150 an ideal addition to mid-length cycles.

Lab Quality Results

What Makes NPP Unique?

Unlike Deca Durabolin, which uses the longer decanoate ester, NPP's phenylpropionate ester allows for quicker release and clearance. This means faster results, better side effect control, and the ability to begin PCT sooner after cycle completion. Clinical studies on Nandrolone confirm its benefits for collagen synthesis, red blood cell production, and anabolic support in both athletic and therapeutic contexts.

Dosing Protocol

Typical NPP dosing is 100–150 mg every other day (300–450 mg per week). Due to its short half-life, frequent injections are necessary for stable blood levels. Most cycles last 6–10 weeks for optimal gains and minimal suppression.

Stacking Suggestions

NPP is a versatile compound and stacks well with a variety of other steroids. Ideal stack partners include:

• Stealth Testosterone Propionate – short ester base for synergy and hormonal balance
• Stealth Trenbolone Acetate – for advanced users seeking maximal recomposition effects
• Stealth Anavar 50 mg – preserves muscle while enhancing fat loss
• Stealth Arimidex 2 mg – helps manage estrogen levels during stack with testosterone

Estrogenic & Androgenic Profile

Although Nandrolone has a lower conversion rate to estrogen compared to testosterone, it still aromatizes to some degree. Using a mild aromatase inhibitor (AI) may be necessary depending on your testosterone ratio and sensitivity. Its androgenic profile is also mild, making it easier on the scalp and skin compared to more aggressive steroids.

PCT Timing & Strategy

One major advantage of NPP is its fast clearance. Post-cycle therapy (PCT) can typically begin just 4–6 days after your final injection. A standard 4-week Clomid or Nolvadex protocol is effective. Some users also incorporate HCG during the cycle to maintain testicular function and ease recovery.
