Halotestin is Xeno Laboratories' fluoxymesterone, a methylated oral anabolic sold as tablets. Its reputation runs ahead of its numbers: it is discussed as the strongest oral for raw force, and almost nobody buys it to add size.
That reputation holds because the compound does one job well. A short block lifts top-end strength without moving scale weight, and the absence of any aromatisation step keeps fluid and chest tissue out of the picture. Everything difficult about it comes from the methyl group rather than from the hormone.
Product Overview
Fluoxymesterone is a 17-alpha-alkylated steroid built on a DHT backbone, the family that cannot be converted to estradiol at any dose. The methyl group at carbon 17 is what lets the tablet survive first-pass metabolism, and it is also why the hepatic load is classed as high. Reference figures put the half-life near nine hours, short enough that one daily tablet leaves obvious gaps and long enough that three or four smaller intakes hold a flatter level.
The clinical record is narrow. The drug was studied as replacement therapy at 5 to 20 mg a day and used palliatively at 10 to 40 mg a day, so athletic amounts sit in the same territory as medical ones. Competition use is strictly short-term: two to four weeks attached to an injectable base such as Xeno testosterone, where the tablets supply the strength edge and the oil does the tissue building.
What it will not do is add muscle. There is no fluid to shed and no dramatic weight shift to expect, so anyone shopping for a bulking oral has picked the wrong item in this line. Anadrol and Dbol 20 fill that slot; fluoxymesterone belongs elsewhere on the calendar.
Dosage Protocol
Published and vendor protocols stay in a narrow band, and the ceiling is not far above the floor.
| Beginner | 10 mg daily across 2-3 weeks, which already matches the top of clinical replacement dosing |
| Intermediate | 10-20 mg daily across 2-4 weeks, split into three or four intakes |
| Advanced | 20-30 mg daily across 2-4 weeks at most; no source describes a longer protocol |
| Female | Not recommended; voice change and hair growth are the documented risks and no athletic female dose appears in the source material |
| Administration | Oral, split across the day because of the short half-life |
Dividing the amount matters more than the total. A single morning tablet leaves the afternoon uncovered, and smaller repeated intakes also smooth out the irritability that a large peak can bring. Because the amount used is small, tablet strength decides how the daily figure is assembled rather than how much hormone is actually taken.
Suggested Protocols
Three placements cover most real use. Every pill in the diagrams links to that product's page in this line.
What to Expect
- Drive and aggression inside days. Users describe a sharp, focused training state early in the block, usually before the weights on the bar have moved at all.
- Force without scale movement. Working loads climb while body weight stays put, which is exactly why this is chosen over a wet oral.
- A tighter, drier look. Subcutaneous fluid is not part of the profile, so definition and vascularity improve over the final fortnight.
- A short window by design. Two to four weeks is the practical limit, and the strength at the end of that window is what the tablets were bought for.
- Mood can shift. Patience and temper are the usually reported irritants, and they track dose rather than training.
- Nothing is kept afterwards. The edge fades once the tablets stop, because the effect was neural and fluid-free rather than structural.
Side Effects and Management
The list is short, and the first two entries explain why the block is measured in weeks rather than months.
Post-Cycle Therapy
The tablets clear quickly, so timing is decided by the injectable underneath rather than by the oral.
