C E Ester 1000 from SciFit:

More Effective Because It Can Be Absorbed More Efficiently!

Regular creatine monohydrate has been shown effective at increasing lean muscle mass muscle strength and athletic performance. However, regular creatine monohydrate is absorbed poorly by the body - and its effectiveness is dependant upon the cells ability to absorb it. The poor absorption rate of regular creatine monohydrate requires the creatine user to ingest large dosages of creatine to achieve desired effect. Because creatine draws water to the cell, and because most ingested creatine monohydrate is not absorbed, unabsorbed creatine will sit outside of the target cell with the water, and this will result in the "creatine bloat." Creatine ethyl ester is creatine monohydrate with an ester attached. This makes creatine ethyl ester far more effective because it can be absorbed more efficiently.
