Anadrol (oxymetholone)
Muscle & Strength · Oral anabolic steroid
Tier C
What this is
The most dramatic 'size' oral — 5-10 kg in first 2-3 weeks common, but much is water. Most hepatotoxic common AAS. Paradoxical gyno mechanism debated — possibly direct estrogen receptor interaction. Used clinically in aplastic anemia and HIV wasting historically. Very high Benefit reflects mass/strength effects; very low Safety reflects nonmedical high-dose oral AAS use.
Mechanism
Potent C17-aa DHT derivative; not aromatized but displays estrogenic side effects via unclear mechanism; massive water/glycogen retention; used historically for anemia
Dose & route
Clinical: 1-5 mg/kg/day in anemia; illicit 50-150 mg/day PO
