Description:Estra-5(10),9(11)-diene-3,17-dione, commonly known as 19-norandrostenedione, is a synthetic anabolic steroid and a derivative of testosterone. It is characterized by a steroid backbone with a diene structure, specifically featuring double bonds at the 5(10) and 9(11) positions, along with ketone functional groups at the 3 and 17 positions. This compound is often studied for its potential effects on muscle growth and performance enhancement, although its use is controversial and banned in many sports due to its anabolic properties. Estra-5(10),9(11)-diene-3,17-dione is typically administered in various forms, including oral and injectable preparations. Its pharmacological effects are primarily attributed to its ability to interact with androgen receptors, influencing protein synthesis and muscle hypertrophy. However, it may also exhibit side effects, including hormonal imbalances and cardiovascular issues. As a controlled substance in many jurisdictions, its use is regulated, and it is important for individuals to be aware of the legal implications and health risks associated with its use.
