Methyltestosterone (brand names Android, Androral, Metandren, Oraviron, Testred, Virilon), also known as 17α-methyltestosterone or as 17α-methylandrost-4-en-17β-ol-3-one, is a synthetic, orally active androgenic-anabolic steroid (AAS) and 17α-methylated derivative of testosterone that is used to treat males with androgen deficiency. It bears close structural similarity to testosterone, but has a methyl group at the C17α position in order to increase oral bioavailability. Due to efficient aromatization into the potent estrogen methylestradiol, methyltestosterone has relatively high estrogenicity and hence potential side effects such as gynecomastia.
This medication is used in men who do not make enough of a natural substance called testosterone. In males, testosterone is responsible for many normal functions, including growth and development of the genitals, muscles, and bones. It also helps cause normal sexual development (puberty) in boys. Methyltestosterone is similar to the natural testosterone produced by your body. It belongs to a class of drugs known as androgens. It works by affecting many body systems so that the body can develop and function normally.
Methyltestosterone may also be used in certain adolescent boys to cause puberty in those with delayed puberty. It may also be used to treat certain types of breast cancer in women.
How to use methyltestosterone:
Take methyltestosterone by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
If you miss a dose of methyltestosterone, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
