In your skeletal muscles, where you build bulk and generate the energy for movement, creatine participates in the complex muscle contraction process to maximize muscle energy. Adenosine Triphosphate, abbreviated to ATP, is a key fuel for muscle contraction, the repetition exercises you perform when bodybuilding. The more ATP you make available to your muscles the more energy created to power bodybuilding and boost performance in bursty sports, like sprinting, rowing, bodybuilding. Normal levels of ATP allow you only a few seconds of high-intensity energy.
Anabolic steroids do have legitimate medical uses. They were first synthesized in the 1930s to treat underdeveloped testes and resulting testosterone deficiency. In the 1950s, they were used to treat anemia and muscle-wasting disorders and to bulk up patients whose muscles had atrophied from extended bed rest. In the 1960s, anabolic steroids were used to treat some forms of dwarfism. Today anabolic steroids are being studied for their ability to alleviate the extreme body wasting associated with acquired immunodeficiency syndrome (AIDS). Their most common use, however, remains among athletes seeking a quick competitive edge.
