17β-Hydroxy-17α-methyl-A-nor-5α-androstan-2-one, also known as methasterone, is a synthetic anabolic steroid derived from the androstane class. It is structurally similar to testosterone, with modifications at the 17α position (methyl group) and the A-ring (nor), which contribute to its enhanced anabolic and androgenic effects. Methasterone is known for its ability to promote muscle growth, strength, and performance enhancement, making it a popular substance among athletes and bodybuilders. However, it is important to note that the use of methasterone and other anabolic steroids is associated with various health risks and is often banned in competitive sports due to its potential for abuse and negative side effects.
