Methyltestosterone, sold under the brand names Android, Metandren, and Testred among others, is an androgen and anabolic steroid (AAS) medication which is used in the treatment of low testosterone levels in men, delayed puberty in boys, at low doses as a component of menopausal hormone therapy for menopausal symptoms like hot flashes, osteoporosis, and low sexual desire in women, and to treat breast cancer in women.[4][5][12][13][14] It is taken by mouth or held in the cheek or under the tongue.[4][13][14][6]

Side effects of methyltestosterone include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire.[4] It can also cause estrogenic effects like fluid retention, breast tenderness, and breast enlargement in men and liver damage.[4] The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).[4][15] It has moderate androgenic effects and moderate anabolic effects, which make it useful for producing masculinization.[4][16]

Methyltestosterone was discovered in 1935 and was introduced for medical use in 1936.[6][17][18][19][4] It was made shortly after the discovery of testosterone and was one of the first synthetic AAS to be developed.[6][17][18] In addition to its medical use, methyltestosterone is used to improve physique and performance, although it is not as commonly used as other AAS for such purposes due to its androgenic effects, estrogenic effects, and risk of liver damage.[4] The drug is a controlled substance in many countries and so non-medical use is generally illicit.[4]
