17α-Ethyl-pregna-4,6-dien-3,20-dion is a synthetic steroid hormone with the chemical formula C21H28O2. It is a derivative of the naturally occurring hormone pregnenolone, featuring an ethyl group at the 17α position. This modification enhances its anabolic properties, making it a potent androgen. The compound is structurally similar to testosterone, but with a double bond between carbons 4 and 6, which differentiates it from other steroids. It is used in veterinary medicine to promote growth and appetite in livestock, and it has been researched for its potential applications in human medicine, particularly in the treatment of conditions related to muscle wasting and anemia. However, due to its potent effects, it is also subject to strict regulation to prevent misuse in sports and other areas.
