Xeno Laboratories Halotestin is supplied as 10 mg fluoxymesterone tablets, a fluorinated 17-alpha-alkylated oral anabolic steroid the literature treats as a severe-end reference compound.
GMP-manufactured and HPLC-verified, with a Certificate of Analysis per batch, and shipped internationally and to the United States as laboratory reference material.
Xeno Laboratories Halotestin is a 10 mg fluoxymesterone tablet supplied as laboratory reference material. Fluoxymesterone is an oral anabolic steroid that carries a fluorine atom at carbon 9 and an 11-beta hydroxyl group alongside the 17-alpha-methyl that lets it survive first-pass metabolism. The literature describes it as highly androgenic and as not aromatising, which places it at the opposite corner of the oral grid from wet compounds such as Dbol 20 mg, and gives laboratories a hard-to-replace extreme for class studies.
Androgen receptor binding with a strongly androgenic profile and no aromatisation step is the mechanism described in the published material, and the clinical record behind the drug is supervised replacement therapy, where published dosage references put the medical ceiling close to the amounts quoted in athletic accounts. Reviews of the oral class put fluoxymesterone in the group with the greatest reported hepatic risk, and the sources describe cholestatic liver injury as a documented concern for the drug. Animal and cell work covers the receptor side; the human record comes from monitored patients.
Hepatotoxicity is the safety topic that dominates the fluoxymesterone literature rather than a footnote, and that warning is attached to the 17-alpha-alkylated structure the molecule shares with its class. Anti-doping sources describe long metabolite detection windows for fluoxymesterone, and the exact period depends on the assay, the amount and the individual, so no single figure is quoted as reliable here. The plasma half-life in pharmacology references runs to several hours, which is a different number from a detection window.
Fluoxymesterone is a controlled substance in many countries and a prescription-only medicine where it remains licensed. This tablet is supplied as laboratory reference material, is not offered as a medicine, and carries no dose, no cycle length and no post-cycle plan. Amounts in the clinical papers describe supervised patients with medical conditions and must not be read as guidance for anyone else.

Before you ask
Halotestin is a trade name for fluoxymesterone, an oral anabolic steroid that carries a fluorine at carbon 9 and a hydroxyl at carbon 11 in addition to the 17-alpha-methyl group that allows oral survival. Published reviews describe it as strongly androgenic and as not aromatising, which is why it appears in the literature at the severe end of oral reference compounds rather than as a routine comparator.
The warning follows from the 17-alpha-alkylated structure that lets the molecule survive first-pass metabolism, and published case series on fluoxymesterone describe cholestatic jaundice and other liver injury in patients who used it under supervision. Reviews of the oral class consistently place it in the highest reported hepatic risk group. This page offers no amount and no duration, and a liver condition makes the class warning decisive.
Pharmacology references quote a plasma half-life of roughly nine hours for fluoxymesterone. On detection the sources disagree: one drug reference describes urine metabolites for about five days after a single 10 mg dose, while vendor profiles quote windows running to weeks. Half-life and detection answer different questions, and both shift with the dose, the individual and the method, so no figure is quoted as a rule here.
Reports of rapid strength change come from athlete accounts and from survey literature rather than from controlled trials, and the clinical record for the drug is supervised replacement therapy rather than anything resembling a training protocol. Reviews that rank oral compounds by side effects rely on the same uncontrolled sources, which is a limitation worth naming instead of repeating the ranking as a measurement.
Fluoxymesterone is an anabolic steroid and therefore a controlled substance in many countries and a prescription-only medicine where a licence remains, so buying, importing or possessing it can be regulated or illegal depending on where you are. This tablet is offered as laboratory reference material with no medical claim. Check your local rules first, and do not treat a research listing as authorisation to hold a controlled drug.
This 10 mg fluoxymesterone pack is listed with international checkout and a U.S. domestic option, and every batch carries an HPLC report and a Certificate of Analysis. Orders are handled within one to two business days. Stock, pack and the current price are shown in the product block above, so check the availability line before ordering rather than assuming a dispatch time.
