Fluoxymesterone, marketed under the pharmaceutical brand name Halotestin, is a synthetic anabolic compound derived from methyltestosterone with one of the highest androgenic to anabolic ratios of any oral anabolic steroid in research, estimated at approximately 19 times the androgenic potency of testosterone with a comparatively modest anabolic rating. F40 Biotech’s formulation delivers 10mg per tablet in a 50 count format, a precisely dosed presentation appropriate for a compound where the research literature references notably low effective concentrations relative to most other oral anabolic compounds.
Fluoxymesterone’s pharmacological profile is defined by several characteristics that make it a distinctly unique research subject within the oral anabolic compound family. It does not aromatize to estrogen, a characteristic shared with other DHT derived compounds, but unlike most non aromatizing anabolics it also actively inhibits aromatase enzyme activity; reducing estrogenic conversion from other compounds present in the research environment in a mechanism comparable to Masteron Propionate among injectables. Halotestin is one of the few oral anabolic compounds with documented direct effects on hemoglobin synthesis and red blood cell production, having been clinically approved for the treatment of anemia, a hematopoietic activity profile that makes it a frequently studied reference compound in research examining androgen driven erythropoiesis.
Halotestin carries one of the most significant hepatotoxicity profiles among oral anabolic compounds. As a 17 alpha alkylated compound it survives first pass hepatic metabolism, but its documented impact on liver stress markers is substantially more pronounced than most other alkylated oral steroids at equivalent doses, a well established characteristic in the clinical literature that makes hepatic function monitoring a critical variable in Fluoxymesterone research protocols. This pronounced hepatic activity profile, combined with its extreme androgenic potency, makes Halotestin one of the more specialized and carefully studied compounds in the oral anabolic research literature.

Halotestin (Fluoxymesterone) is a 17-alpha alkylated testosterone derivative with an extraordinarily high anabolic to androgenic ratio of 1900:850 compared to testosterone's 100:100. Making it one of the most potent androgenic compounds in the research catalogue. Originally developed by Upjohn Pharmaceuticals for hypogonadism, delayed puberty, and breast cancer research, Halotestin is studied for its exceptional strength enhancement properties, aggressive CNS stimulation, hematopoietic effects through erythropoietin stimulation, and unique ability to increase aggression and neuromuscular efficiency without the mass gains associated with most other potent anabolic compounds. It does not aromatize to estrogen and has no progestin activity.
Fluoxymesterone produces dramatic strength and aggression increases through powerful androgen receptor activation and CNS stimulation but produces relatively modest lean mass gains compared to its androgenic potency. This dissociation between strength and mass is attributed to its strong binding to androgen receptors in CNS and neuromuscular tissue, its hematopoietic effects increasing oxygen carrying capacity, and its unique interaction with glucocorticoid receptors. These properties make Halotestin the most studied oral compound for acute strength and aggression research, particularly studied as a pre competition or pre event compound where maximum strength output without weight gain is the research objective.
Fluoxymesterone is one of the most hepatotoxic oral anabolic compounds available; its 17-AA modification combined with its potent androgenic activity produces significant hepatic stress even at low doses and short cycle durations. Research protocols with Halotestin are typically limited to 4 weeks maximum duration at doses of 10–20mg daily. Liver enzyme monitoring (ALT, AST) before, during, and after the research protocol is essential. Liver support with TUDCA at 500mg daily and NAC at 1200mg daily is strongly recommended for the entire duration of any Halotestin research protocol. Alcohol consumption should be avoided entirely during Halotestin research.
Fluoxymesterone has a half-life of approximately 9.2 hours, typically administered once or twice daily in research protocols. Common research doses range from 10–20mg daily; a single 10mg tablet once daily at the conservative end, or two 10mg tablets split morning and pre training for protocols targeting 20mg daily. Research cycle duration is typically 2–4 weeks maximum given Halotestin's exceptional hepatotoxicity. The 50 tablet pack at 10mg provides 500mg total, sufficient for 25–50 days of research at 10–20mg daily.
Yes! This batch has been independently HPLC tested by an accredited third party laboratory confirming concentration accuracy at 10mg per tablet and compound identity as Fluoxymesterone. A certificate of analysis is available.
