Nandrolone Decanoate vs Sustanon 250
A side-by-side research comparison of Nandrolone Decanoate and Sustanon 250 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Nandrolone Decanoate | Sustanon 250 |
|---|---|---|
| Full name | Nandrolone Decanoate (Deca-Durabolin) | Sustanon 250 (Testosterone Ester Blend) |
| 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. | Combines short, medium, and long esters so testosterone is released at staggered rates, producing a rapid initial rise followed by sustained levels. The active hormone is standard testosterone acting on androgen receptors. |
| Molecular weight | 428.6 Da | Blend (varies by ester) |
| Half-life | ~6-12 days | Mixed (~1 day to ~2 weeks across esters) |
| Bioavailability | Intramuscular injection | Intramuscular injection |
| Typical dose | Medical: ~50-100 mg every 1-4 weeks | Medical: ~250 mg every 2-3 weeks (varies) |
| Frequency | Weekly to monthly (medical) | Every 1-3 weeks (medical) |
| Route | Intramuscular injection | Intramuscular injection |
