Methenolone Enanthate vs Nandrolone Decanoate
A side-by-side research comparison of Methenolone Enanthate and Nandrolone Decanoate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Methenolone Enanthate | Nandrolone Decanoate |
|---|---|---|
| Full name | Methenolone (Primobolan) | Nandrolone Decanoate (Deca-Durabolin) |
| 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. | Nandrolone is testosterone lacking the 19-carbon methyl group, giving it high anabolic and lower androgenic activity. It binds androgen receptors and, unlike testosterone, converts to a weaker androgen (rather than DHT) in some tissues, reducing certain androgenic effects but not estrogen-related ones. |
| Molecular weight | 414.6 Da (enanthate) | 428.6 Da |
| Half-life | ~5-7 days (enanthate) | ~6-12 days |
| Bioavailability | Intramuscular injection or oral | Intramuscular injection |
| Typical dose | Lean-gain cycles (non-medical) | Medical: ~50-100 mg every 1-4 weeks |
| Frequency | Weekly (injectable) or daily (oral) | Weekly to monthly (medical) |
| Route | Intramuscular injection or oral tablet | Intramuscular injection |
