Nandrolone Decanoate vs Trenbolone Enanthate
A side-by-side research comparison of Nandrolone Decanoate and Trenbolone Enanthate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Nandrolone Decanoate | Trenbolone Enanthate |
|---|---|---|
| Full name | Nandrolone Decanoate (Deca-Durabolin) | Trenbolone Enanthate (Long-Ester Tren) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Prescription drug (controlled substance) | Not medically approved (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. | Identical active hormone to trenbolone acetate, delivered with a longer enanthate ester for slower release. Retains very high androgen-receptor affinity, strong anabolic/androgenic action, no aromatization, and progestogenic activity. |
| Molecular weight | 428.6 Da | 382.5 Da |
| Half-life | ~6-12 days | ~5-7 days |
| Bioavailability | Intramuscular injection | Intramuscular injection |
| Typical dose | Medical: ~50-100 mg every 1-4 weeks | Highly potent; low absolute doses |
| Frequency | Weekly to monthly (medical) | Twice weekly |
| Route | Intramuscular injection | Intramuscular injection |
