Fluoxymesterone vs Testosterone Enanthate
A side-by-side research comparison of Fluoxymesterone and Testosterone Enanthate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Fluoxymesterone | Testosterone Enanthate |
|---|---|---|
| Full name | Fluoxymesterone (Halotestin) | Testosterone Enanthate (Long-Ester Testosterone) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | FDA-approved drug (controlled substance) | FDA-approved 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. | A testosterone molecule attached to an enanthate ester that slows release from the injection site. Once cleaved, testosterone binds androgen receptors to increase muscle protein synthesis, nitrogen retention, red blood cell production, and secondary sexual characteristics. |
| Molecular weight | 336.4 Da | 400.6 Da |
| Half-life | ~9 hours | ~4.5-5 days |
| Bioavailability | Oral | Intramuscular/subcutaneous injection |
| Typical dose | Medical: ~2.5-20 mg/day | TRT ~100-200 mg/week (medical) |
| Frequency | Daily | 1-2x weekly |
| Route | Oral tablet | Intramuscular or subcutaneous injection |
