Oxabolone Cipionate
4-hydroxy-19-nortestosterone cipionate — an injectable 19-nor AAS with a hydroxyl group at C4. Very low androgenic activity. Marketed in Italy (Sterobol) for anemia and muscle-wasting conditions. Essentially non-virilizing at therapeutic doses, making it one of the most androgenically mild compounds available.
Mechanism of Action
4-hydroxy modification combined with 19-nor structure produces near-complete androgenic attenuation while preserving moderate anabolic activity. Does not aromatize (4-hydroxy blocks aromatase). Mild progestogenic activity from the 19-nor scaffold. Very low SHBG binding.
Typical Dosing
⚠ Warning Flags
