Methandrostenolone vs Nandrolone Decanoate
A side-by-side research comparison of Methandrostenolone and Nandrolone Decanoate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Methandrostenolone | Nandrolone Decanoate |
|---|---|---|
| Full name | Methandrostenolone (Dianabol / Dbol) | Nandrolone Decanoate (Deca-Durabolin) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Not medically approved (controlled substance) | Prescription drug (controlled substance) |
| Mechanism | A 17-alpha-alkylated testosterone derivative that is orally active and mildly aromatizes to estrogen. It strongly increases protein synthesis, glycogen storage, and nitrogen retention, producing quick weight and strength gains. | 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 | 300.4 Da | 428.6 Da |
| Half-life | ~3-6 hours | ~6-12 days |
| Bioavailability | Oral | Intramuscular injection |
| Typical dose | Short "kickstart" cycles (non-medical) | Medical: ~50-100 mg every 1-4 weeks |
| Frequency | Daily (often split) | Weekly to monthly (medical) |
| Route | Oral tablet | Intramuscular injection |
