Comparison table
| Attribute | Fluoxymesterone | Sustanon 250 |
|---|---|---|
| Full name | Fluoxymesterone (Halotestin) | Sustanon 250 (Testosterone Ester Blend) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | FDA-approved drug (controlled substance) | Prescription drug (controlled substance) |
| Mechanism | A 17-alpha-alkylated, fluorinated derivative of methyltestosterone with extremely high androgenic potency. It boosts strength, aggression, and red blood cells rapidly but does little for muscle size. | 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 | 336.4 Da | Blend (varies by ester) |
| Half-life | ~9 hours | Mixed (~1 day to ~2 weeks across esters) |
| Bioavailability | Oral | Intramuscular injection |
| Typical dose | Medical: ~2.5-20 mg/day | Medical: ~250 mg every 2-3 weeks (varies) |
| Frequency | Daily | Every 1-3 weeks (medical) |
| Route | Oral tablet | Intramuscular injection |
