What is fluoxymesterone?

Fluoxymesterone is an oral androgen, a 17-alpha-methylated, fluorinated derivative of testosterone. It was sold in the US as Halotestin tablets.

Also known as: Halotestin, Android-F, Ora-Testryl.

Former US tablet strengths

Halotestin came as 2 mg, 5 mg and 10 mg scored tablets. Drugs@FDA lists Halotestin and the US generics as discontinued.

Approval status and how it is used

The Halotestin label (2002) indicated fluoxymesterone for testosterone replacement in men with primary or secondary hypogonadism, for confirmed delayed puberty, and for palliation of certain hormone-dependent breast cancers in women. For replacement in men it gave 5 to 20 mg daily, taken at once or split into three or four doses. Drugs@FDA lists Halotestin and every US generic fluoxymesterone application as discontinued.

Anabolic steroids are Schedule III controlled substances in the US. Use without a prescription is illegal, and the labels warn about liver damage (including peliosis hepatis and liver tumors), cholesterol changes and suppression of the body's own testosterone and sperm production.

How to track fluoxymesterone in Dose Track

  1. Add fluoxymesterone from the built-in list. It sits next to everything else you take, so a GLP-1, TRT and a few peptides all live in one log.
  2. Log each tablet when you take it, including split or fractional tablets, so your history shows exactly what you took and when.
  3. Set reminders on your own schedule, whether that is daily, weekly or every few days.
  4. Your log stays on your phone.
