Testosterone and its derivate are made synthetically pharmaceutically as drugs for many different treatments. Pharmaceutical research of anabolic steroid is not focused a lot on muscle grow in healthy individuals but only in some aging related diseases like sarcopenia – the loss of skeletal muscle mass and strength as a result of aging. Osteoporosis is one of the aging diseases that is also sometimes treated with anabolic steroids.
