Nandrolone Phenylpropionate vs Stanozolol
A side-by-side research comparison of Nandrolone Phenylpropionate and Stanozolol across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Nandrolone Phenylpropionate | Stanozolol |
|---|---|---|
| Full name | Nandrolone Phenylpropionate (NPP) | Stanozolol (Winstrol) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Prescription drug (controlled substance) | FDA-approved drug (controlled substance) |
| Mechanism | 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. | Stanozolol is a 17-alpha-alkylated DHT derivative that is orally active and resists aromatization. It has a relatively high anabolic-to-androgenic ratio and lowers sex-hormone-binding globulin (SHBG), increasing free hormone levels. |
| Molecular weight | 406.6 Da | 328.5 Da |
| Half-life | ~2.5-4.5 days | ~9 hours (oral), ~24 hours (injectable) |
| Bioavailability | Intramuscular injection | Oral or intramuscular injection |
| Typical dose | Variable; more frequent than Deca | Medical: variable for angioedema |
| Frequency | Every 2-3 days | Daily (oral) |
| Route | Intramuscular injection | Oral tablet or aqueous injection |
Nandrolone Phenylpropionate reported benefits
- Lean mass gains
- Faster onset than Deca
- Faster clearance (flexibility)
- Reputed joint comfort
Stanozolol reported benefits
- Lean, dry strength gains
- No water retention
- Lowers SHBG (more free hormone)
- Treats hereditary angioedema (medical)
