Anabolic steroids work by helping the body's muscle cells produce more protein which, as long as the athletes works out, leads to increased muscle size and strength and, at the same time, also allows the body to produce more ATP, the "fuel" muscles need to move.These drugs also appear to increase blood volume and glycogen (blood sugar), and to inhibit the natural process whereby muscles cells that are no longer required are eliminated
Anabolic steroids work by stimulating the anabolic effect by binding or plugging into protein receptors in or on the cells that help create new proteins in the cells. This increased biological activity is called an increase in Ribonucleic Acid Activity (RNA Activity). The construction of new proteins helps increase muscle size and strength. Remember, this normally happens in the body. The steroids stimulate or increase this biological process by binding to the receptor sites on the protein cells.
