Summary: 1-Testosterone is an anabolic steroid. Anabolic steroids are structurally similar to cyclic steroids and essentially increase protein within the cells. 1-Testosterone has similar effects on the body as testosterone, especially within the skeletal muscles where athletes most require enhancement. In addition to helping the body rebuild tissues, it also allows calories to be absorbed adequately and can be taken routinely when incorporated into a healthy, sports-oriented diet for the appropriate amount of time in order to produce desired results. 1-Testosterone is available typically in tablet form.
