2α-methylandrost-4-ene-3,17-dione, also known as methyltestosterone or Android, is a synthetic androgen and anabolic steroid derivative of testosterone. It is a 17-alkylated compound, which means it has a methyl group attached to the 17th carbon atom, enhancing its oral bioavailability. This modification allows the drug to be more resistant to liver metabolism, making it suitable for oral administration. Methyltestosterone is used medically to treat conditions like delayed puberty, hypogonadism, and breast cancer in women. It is also used off-label for its anabolic effects to promote muscle growth and strength, although its use for this purpose is controversial due to potential side effects and health risks. The drug is classified as a controlled substance in many countries due to its potential for abuse and serious side effects, which can include liver damage, cardiovascular issues, and hormonal imbalances.
