Nandrolone Decanoate vs Oxymetholone
A side-by-side research comparison of Nandrolone Decanoate and Oxymetholone across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Nandrolone Decanoate | Oxymetholone |
|---|---|---|
| Full name | Nandrolone Decanoate (Deca-Durabolin) | Oxymetholone (Anadrol) |
| 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. | Oxymetholone is a 17-alpha-alkylated derivative of DHT that strongly stimulates erythropoiesis and protein synthesis. Despite its DHT origin, it can produce estrogen-like effects through a non-aromatizing mechanism, contributing to water retention. |
| Molecular weight | 428.6 Da | 332.5 Da |
| Half-life | ~6-12 days | ~8-9 hours |
| Bioavailability | Intramuscular injection | Oral |
| Typical dose | Medical: ~50-100 mg every 1-4 weeks | Medical: ~1-5 mg/kg/day for anemia |
| Frequency | Weekly to monthly (medical) | Daily |
| Route | Intramuscular injection | Oral tablet |
