Creatine ethylester, also known as creatine ester, cre-ester and CEE, is a substance sold as a painkiller for athletic performance and for muscle death in bodybuilding. It is an ethyl ester derivative of creatine, from which it is made. In the body, CEE is converted back into creatine. CEE is said to have a much better absorption rate and a longer half-life in the body than regular creatine monohydrate, because it is slightly more lipophilic. It is also proposed to bypass the creatine transporter, thereby increasing skeletal muscle uptake of creatine and leading to an increased ability to regenerate ATP. However, in a published study comparing the two, CEE was not as effective at increasing serum and muscle creatine levels or in improving body composition, muscle mass, strength, and power. The same study found CEE to be comparable to placebo, but said study had a total sample size of 30 individuals. If you know anything about statistics, this is an inadequate number.
As a supplement, the compound was developed, patented and licensed through UNeMed, the technology transfer entity of the University of Nebraska Medical Center, and is sold under numerous brand names.
