Turkesterone is a type of ecdysteroid, which is a natural steroid hormone found in plants and insects. It is synthesized by plants from cholesterol and has a similar molecular structure to testosterone, although it works differently in the body. Unlike anabolic steroids, turkesterone does not bind to human steroid receptors or alter natural production, but instead acts as an influencer to signal pathways like protein synthesis. It has been marketed as a safe alternative to anabolic steroids, as it is a naturally occurring plant compound and studies have shown that it produces muscle gains that are greater than those achieved from using many common anabolic steroids. However, it is not legally classified as a steroid.
