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.
