What is Halotestin?
Fluoxymesterone (Halotestin) is a 17α-alkylated halogenated DHT derivative with the highest androgenic rating of any oral AAS (~1900:1900). Does not aromatise. Research: extreme androgenic receptor studies, CNS androgen effects, erythropoiesis, and comparative AAS receptor selectivity at the high-androgenicity end. CAS 76-43-7.
Research Applications
High Androgenicity Reference
1900:1900 androgenic:anabolic — extreme AAS spectrum reference
Non-Aromatising
17α-fluorinated — no estrogen conversion — pure androgen
CNS Androgen Research
Aggression and CNS AR distribution models
Erythropoiesis
EPO stimulation — red blood cell mass studies
Comparative AAS Panel
Highest-androgenicity compound for selectivity studies
