Methenolone Enanthate vs Nandrolone Phenylpropionate
A side-by-side research comparison of Methenolone Enanthate and Nandrolone Phenylpropionate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Methenolone Enanthate | Nandrolone Phenylpropionate |
|---|---|---|
| Full name | Methenolone (Primobolan) | Nandrolone Phenylpropionate (NPP) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Prescription drug (controlled substance) | Prescription drug (controlled substance) |
| Mechanism | Methenolone is a DHT derivative with modest anabolic and low androgenic activity. It does not aromatize and is generally well tolerated, though the oral acetate form is not 17aa and survives via a 1-methyl group, giving lower liver stress than typical orals. | 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. |
| Molecular weight | 414.6 Da (enanthate) | 406.6 Da |
| Half-life | ~5-7 days (enanthate) | ~2.5-4.5 days |
| Bioavailability | Intramuscular injection or oral | Intramuscular injection |
| Typical dose | Lean-gain cycles (non-medical) | Variable; more frequent than Deca |
| Frequency | Weekly (injectable) or daily (oral) | Every 2-3 days |
| Route | Intramuscular injection or oral tablet | Intramuscular injection |
