What is Nandrolone Phenylpropionate?
Nandrolone Phenylpropionate (NPP) is a potent anabolic steroid derived from testosterone, famed in the bodybuilding circle for its muscle growth is a 19-nortestosterone (nandrolone) derivative with a phenylpropionate ester, giving it a shorter half-life than nandrolone decanoate (Deca-Durabolin). It’s used for muscle growth, joint relief, and performance enhancement.
Key Features: nandrolone phenylpropionate
- Ester Half-Life: ~4.5 days (injections every 3–4 days).
- Anabolic/Androgenic Ratio: 125:37 (high muscle-building, moderate androgenic effects).
- Medical Uses: Rarely prescribed today but historically used for osteoporosis, anemia, and muscle-wasting conditions.
Dosage Guide Table Nandrolone Phenylpropionate
| Purpose | Men | Women |
|---|---|---|
| Medical Use | 50–100mg/week (rarely prescribed). | Avoid (high virilization risk). |
| Bodybuilding | 300–600mg/week (split into 2–3 injections). | Not recommended (androgenic side effects). |
| Cycle Length | 8–12 weeks (with testosterone base). | — |
Notes:
- Injection Frequency: Every 3–4 days due to short ester.
- Testosterone Base: Required to avoid low-T side effects (low libido, fatigue).
- Women: Extreme risk of voice deepening, clitoral enlargement, and hair loss.
Primary Uses of Nandrolone Phenylpropionate nandrolone phenylpropionate
- Muscle Growth: Promotes lean mass gains with minimal water retention (vs. testosterone).
- Joint/Collagen Support: Reduces joint pain by increasing collagen synthesis.
- Bulking Cycles: Often stacked with testosterone, Dianabol, or Anadrol.
- Cutting Cycles: Used at lower doses to preserve muscle in a calorie deficit.
Importance
- Faster Results: Shorter ester allows quicker effects than nandrolone decanoate.
- Progestogenic Activity: Binds to progesterone receptors (caution with estrogenic compounds).
- Low Estrogenic Side Effects: Minimal aromatization but may still cause progesterone-related gyno.
Products to Use with Caution
| Avoid/Use Carefully | Reason |
|---|---|
| Estrogenic Steroids (e.g., testosterone, Dianabol) | Increases risk of progesterone/estrogen-driven gyno. |
| Hepatotoxic Orals (e.g., Anadrol, Winstrol) | Adds liver strain. |
| Dopamine Antagonists (e.g., antipsychotics) | May worsen prolactin-related side effects. |
| Alcohol | Exacerbates cholesterol imbalances and liver stress. |
Why Buy NPP? Nandrolone Phenylpropionate
- Joint Relief: Popular among athletes for reducing chronic joint pain.
- Lean Gains: Less water retention compared to testosterone or Deca.
- Shorter Cycle Flexibility: Faster clearance from the body than decanoate.
Formulation & Storage nandrolone phenylpropionate
- Form: Oil-based injectable (common concentrations: 100mg/mL or 200mg/mL).
- Storage: Room temperature (avoid sunlight); stable for 2–3 years unopened.
- Half-Life: ~4.5 days (requires frequent injections).
Side Effects
- Androgenic: Acne, hair loss (if prone to male-pattern baldness).
- Progestogenic: Gynecomastia, elevated prolactin (manage with Cabergoline).
- Cardiovascular: Lowers HDL (“good” cholesterol), raises LDL.
- Suppression: Shuts down natural testosterone (PCT with Clomid/Nolvadex essential).
Legal Status
- Prescription-Only: Controlled substance in most countries (e.g., Schedule III in the U.S.).
- Underground Labs: High risk of counterfeit or underdosed products.
Key Considerations
- Bloodwork: Monitor cholesterol, liver enzymes, and prolactin.
- Progesterone Management: Use Cabergoline if prolactin rises.
- PCT: Start 2–3 weeks post-cycle to restore natural hormone production.
Final Note
NPP is effective for muscle growth and joint health but carries risks like progesterone-related gyno and cholesterol issues. Always use under medical supervision for HRT and avoid self-prescription. Prioritize health markers and post-cycle recovery. nandrolone phenylpropionate
