Nandrolone Decanoate vs Testosterone Propionate
A side-by-side research comparison of Nandrolone Decanoate and Testosterone Propionate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Nandrolone Decanoate | Testosterone Propionate |
|---|---|---|
| Full name | Nandrolone Decanoate (Deca-Durabolin) | Testosterone Propionate (Short-Ester Testosterone) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Prescription drug (controlled substance) | Prescription 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. | Testosterone bound to a small propionate ester, giving rapid release and a short half-life. It acts on androgen receptors identically to other testosterone forms but with faster onset and offset of blood levels. |
| Molecular weight | 428.6 Da | 344.5 Da |
| Half-life | ~6-12 days | ~0.8-2 days |
| Bioavailability | Intramuscular injection | Intramuscular/subcutaneous injection |
| Typical dose | Medical: ~50-100 mg every 1-4 weeks | Variable; frequent dosing required |
| Frequency | Weekly to monthly (medical) | Every 1-2 days |
| Route | Intramuscular injection | Intramuscular or subcutaneous injection |
Nandrolone Decanoate reported benefits
