Studies have shown that ingesting creatine mono hydrate raises the level of creatine phosphate in muscles thereby increasing strength and the ability to sustain intense exercise.
Creatine is an amino acid used in muscles to supply energy to the muscle cell.
It is not a building-block amino acid used to build muscle protein. Creatine is no stranger to athletes because it appears to provide an edge in competition. Just ask the Denver Broncos and Mark McGuire. It does not enhance aerobic performance. Under the 1994 Dietary and Food Supplement Health and Education Act it is available without a prescription.
