What is Fluoxymesterone (Halotestin)?
Fluoxymesterone (Halotestin) is one of the most potent oral androgens — a 17α-methylated, 9α-fluorinated testosterone derivative with extremely high AR binding affinity and androgenic potency. Does not aromatise due to 11β-hydroxyl group. Research tool for high-potency AR agonism, haematological androgen effects (erythropoiesis), and extreme androgenic activity studies. Research use only.
Research Applications
High-Potency AR Agonism
Extreme androgenic potency — AR binding affinity studies, gene transactivation
Fluorinated Steroid Pharmacology
9α-fluoro group effect on metabolic stability, AR affinity, receptor selectivity
Erythropoiesis Research
Androgenic EPO upregulation, haematocrit response to potent oral androgens
Hepatotoxicity Studies
17α-methyl oral AAS — high-dose hepatic enzyme induction, ALT/AST markers
Comparative High-Potency AAS
Fluoxymesterone vs methylstenbolone, methyltestosterone — potency ranking
