Nandrolone Phenylpropionate vs Oxymetholone
A side-by-side research comparison of Nandrolone Phenylpropionate and Oxymetholone across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Nandrolone Phenylpropionate | Oxymetholone |
|---|---|---|
| Full name | Nandrolone Phenylpropionate (NPP) | Oxymetholone (Anadrol) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Prescription drug (controlled substance) | FDA-approved drug (controlled substance) |
| Mechanism | Same active hormone as Deca (nandrolone) but with a shorter phenylpropionate ester, giving quicker onset and faster clearance. Acts on androgen receptors with high anabolic and reduced androgenic activity. | 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 | 406.6 Da | 332.5 Da |
| Half-life | ~2.5-4.5 days | ~8-9 hours |
| Bioavailability | Intramuscular injection | Oral |
| Typical dose | Variable; more frequent than Deca | Medical: ~1-5 mg/kg/day for anemia |
| Frequency | Every 2-3 days | Daily |
| Route | Intramuscular injection | Oral tablet |
