Fluoxymesterone vs Testosterone Suspension
A side-by-side research comparison of Fluoxymesterone and Testosterone Suspension across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Fluoxymesterone | Testosterone Suspension |
|---|---|---|
| Full name | Fluoxymesterone (Halotestin) | Testosterone Suspension (Ester-Free Testosterone) |
| 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. | Because it has no ester, the full testosterone molecule is immediately available after injection, producing a fast, sharp rise in blood testosterone and correspondingly rapid clearance. |
| Molecular weight | 336.4 Da | 288.4 Da |
| Half-life | ~9 hours | Very short (hours) |
| Bioavailability | Oral | Intramuscular injection |
| Typical dose | Medical: ~2.5-20 mg/day | Very frequent dosing required |
| Frequency | Daily | Daily or multiple times daily |
| Route | Oral tablet | Intramuscular injection |
Fluoxymesterone reported benefits
- Rapid strength gains
