NPP 150 by Dragon Pharma contains Nandrolone Phenylpropionate, a fast-acting anabolic steroid known for its ability to promote lean muscle growth, enhance recovery, and support joint health. Each 10 ml vial delivers 150 mg/ml, ideal for bodybuilders seeking quality gains with minimal water retention. With a half-life of approximately 2–4 days, NPP 150 provides quick results, making it a versatile choice for a strong, defined physique.

What It Is

Nandrolone Phenylpropionate, commonly known as NPP or Durabolin, is a shorter-ester version of nandrolone, a 19-nor anabolic steroid. Originally developed for medical use in treating muscle wasting, anemia, and osteoporosis, it's widely used in bodybuilding for its anabolic properties, promoting muscle growth and joint relief with lower estrogenic activity than testosterone. Its fast-acting ester requires more frequent injections than Deca-Durabolin (nandrolone decanoate).

How It Works

NPP binds to androgen receptors, enhancing protein synthesis and nitrogen retention to promote muscle growth and recovery. It increases collagen synthesis and bone density, supporting joint health and reducing injury risk during heavy lifting. NPP has a low aromatization rate (about 20% of testosterone), minimizing estrogenic side effects, but it can still convert to progesterone, requiring careful monitoring. Its detection time is up to 12–18 months due to its metabolites.

Benefits

  • Lean Muscle Gains: Adds 5–10 lbs of quality muscle in 6–10 weeks.
  • Faster Recovery: Speeds up muscle repair and reduces soreness.
  • Joint Support: Enhances collagen synthesis for stronger joints and tendons.
  • Strength Increase: Boosts power for intense workouts.
  • Low Water Retention: Delivers a defined, aesthetic physique.

Who It's For

NPP 150 is ideal for male bodybuilders aged 21–40 seeking lean muscle growth, recovery, and joint support in bulking or cutting cycles. It's suitable for intermediate to advanced users familiar with anabolic steroids. Not for: Women (due to virilization risks), individuals under 21, or those with prostate, liver, or cardiovascular issues. Medical supervision and blood work are essential.

How to Use

Dosage: Typical dosage for men is 150–450 mg/week (1–3 ml), split into 2–3 injections (e.g., 100–150 mg every other day). Women, if using, should not exceed 50–100 mg/week under strict medical supervision due to virilization risks.

Administration: Inject intramuscularly (e.g., glutes, quads) using a 1-inch needle (22–25G). Rotate injection sites to avoid irritation. Administer on an empty stomach or post-workout for optimal absorption. Cycles typically last 6–10 weeks for balanced results.

Results Timeline: Muscle gains and recovery improvements are noticeable within 2–3 weeks, with peak results (5–10 lbs muscle) by 6–8 weeks when paired with a high-protein diet and training.

Stacking Suggestions

NPP 150 is versatile for stacking:

  • Bulking Stack: Combine with Testosterone Enanthate (250–500 mg/week) and Dianabol (20–40 mg/day) for massive muscle gains.
  • Cutting Stack: Pair with Winstrol (25–50 mg/day) or Anavar (20–50 mg/day) for lean muscle and definition.
  • Support: Use Arimidex (0.5–1 mg EOD) to manage potential estrogenic or progestogenic side effects.

Side Effects

NPP 150 may cause:

  • Progestogenic: Gynecomastia, water retention due to progesterone activity; use anti-progestins if needed.
  • Androgenic: Acne, hair loss (if predisposed), or increased body hair.
  • Hormonal: Significant testosterone suppression; PCT required.
  • Cardiovascular: Potential cholesterol imbalance or blood pressure elevation; monitor lipids.
  • Hepatotoxicity: Minimal, as it's injectable, but monitor liver function.

Regular blood work to monitor testosterone, estrogen, progesterone, and lipids is recommended.

Post Cycle Therapy (PCT)

NPP 150 causes significant testosterone suppression, requiring PCT. Start Clomid (50 mg/day) and Nolvadex (20–40 mg/day) for 4–6 weeks, 3–5 days after the last injection. Include HCG (500–1000 IU EOD) for the first 2 weeks of PCT to restore testicular function. Monitor testosterone, LH, and FSH levels via blood work.

Frequently Asked Questions

What is Nandrolone Phenylpropionate?

Nandrolone Phenylpropionate (NPP) is a fast-acting anabolic steroid, a shorter-ester version of nandrolone, used for lean muscle growth, recovery, and joint support in bodybuilding.

What is Nandrolone Phenylpropionate used for?

NPP is used in bodybuilding for lean muscle gains, strength, and recovery, and medically for muscle wasting, anemia, and osteoporosis, with benefits for joint health.

How long does Nandrolone Phenylpropionate take to kick in?

NPP starts working within 2–3 weeks, with noticeable muscle gains, strength, and recovery improvements by 4–6 weeks when paired with proper diet and training.

How long until you test negative for Nandrolone Phenylpropionate?

NPP has a detection time of up to 12–18 months in drug tests due to its long-lasting metabolites, depending on dosage, cycle length, and individual metabolism.

Does Nandrolone affect sperm?

Yes, Nandrolone can reduce sperm count and fertility due to testosterone suppression. Using HCG during cycles and proper PCT can help mitigate these effects.

Does Nandrolone increase aggression?

Nandrolone has low androgenic activity and is less likely to increase aggression compared to testosterone or trenbolone, but mild mood changes may occur in some users.
