Nandrolone Decanoate vs Testosterone Enanthate
A side-by-side research comparison of Nandrolone Decanoate and Testosterone Enanthate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Nandrolone Decanoate | Testosterone Enanthate |
|---|---|---|
| Full name | Nandrolone Decanoate (Deca-Durabolin) | Testosterone Enanthate (Long-Ester Testosterone) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Prescription drug (controlled substance) | FDA-approved drug (controlled substance) |
| Mechanism | 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. | A testosterone molecule attached to an enanthate ester that slows release from the injection site. Once cleaved, testosterone binds androgen receptors to increase muscle protein synthesis, nitrogen retention, red blood cell production, and secondary sexual characteristics. |
| Molecular weight | 428.6 Da | 400.6 Da |
| Half-life | ~6-12 days | ~4.5-5 days |
| Bioavailability | Intramuscular injection | Intramuscular/subcutaneous injection |
| Typical dose | Medical: ~50-100 mg every 1-4 weeks | TRT ~100-200 mg/week (medical) |
| Frequency | Weekly to monthly (medical) | 1-2x weekly |
| Route | Intramuscular injection | Intramuscular or subcutaneous injection |
