There is no dose this library recommends for healthy people. Fluoxymesterone (Halotestin) is a DEA Schedule III controlled prescription steroid; any legitimate use is a supervised medical decision for a narrow, now largely historical indication. For context only, historical prescribing ranged from roughly 5–20 mg/day orally for androgen replacement or delayed puberty, and palliative breast-cancer regimens used on the order of 10–30 mg/day in divided doses — figures provided for context, not as a recommendation. Illicit pre-contest bodybuilding 'Halo' dosing (commonly tens of mg/day) is unstudied for benefit in healthy people, unmonitored, hepatotoxic, and used without liver-function, lipid or hormonal-axis monitoring.

Oral fluoxymesterone tablets (Halotestin) — for supervised medical use in narrow, largely historical indications only; no performance or longevity form is endorsed

• Any non-medical use — a DEA Schedule III controlled prescription steroid; possession or use without a prescription is illegal, and it is NOT a dietary supplement
• Pre-existing liver disease — fluoxymesterone is notoriously hepatotoxic (cholestasis, peliosis hepatis, hepatic tumors) and should never be added to a compromised liver
• Anyone seeking it for body composition, performance or anti-aging — there is no healthy-population evidence of benefit and a heavy hepatotoxic/virilizing harm profile

• Warfarin / oral anticoagulants
• Hepatotoxic drugs / alcohol
• Insulin / oral hypoglycemics
