What is Fluoxymesterone (Halotestin)?
Fluoxymesterone (brand name Halotestin) is one of the most potent androgenic oral steroids ever developed. Originally created by Upjohn in 1956 and approved by the FDA in 1957, Halotestin was designed for treating hypogonadism and delayed puberty. However, due to its extreme hepatotoxicity and androgenic side effects, it is rarely prescribed today.
In bodybuilding and powerlifting, Halotestin is known as a pre-contest and strength-peaking compound. It does NOT build significant muscle mass. Instead, it dramatically increases aggression, mental focus, strength, and muscle hardness — making it ideal for powerlifting meets, strongman competitions, and bodybuilding peak week.
Halotestin is one of the most toxic oral steroids available. It is strictly for advanced users. It is NOT a mass builder. DO NOT use it for general bulking or first cycles. This compound is for experienced strength athletes peaking for competition within 2-4 weeks.
⚙️ How Does Halotestin Work?
Fluoxymesterone is a 17-alpha-alkylated derivative of testosterone with unique properties:
- ⬆ Extreme androgen receptor binding — Androgenic ratio of 850 (testosterone=100)
- ⬆ CNS stimulation — Increases central nervous system drive, aggression, and focus
- ⬆ Free testosterone — Lowers SHBG, increasing free androgens
- ⬆ Red blood cell production — Increases oxygen-carrying capacity and endurance
- ⬆ Muscle hardness — Reduces subcutaneous water, creating a dry, grainy appearance
- NO aromatization — Zero estrogen conversion, no water retention or gynecomastia
- NO progestin activity — No prolactin-related side effects
Halotestin 10mg — Dosage Protocols
| User Level | Daily Dose | Cycle Length | Primary Use | Expected Strength Increase |
|---|---|---|---|---|
| Beginner (with AAS experience) | 10-20mg (1-2 tabs) | 2-3 weeks | Strength peaking for novice powerlifters | 5-10% |
| Intermediate | 20-30mg (2-3 tabs split) | 2-4 weeks | Pre-meet strength / contest prep | 10-15% |
| Advanced | 30-40mg (3-4 tabs split) | 2-4 weeks | Elite powerlifting / strongman peak | 15-20% |
Critical: Cycle length should NEVER exceed 4 weeks. Hepatotoxicity is severe. Do not use Halotestin for more than 4 weeks consecutively under any circumstances.
