Creatine Ethyl Ester
Also known as CEE. Creatine ethyl ester is alleged to be more stable, soluble and bioavailable than creatine monohydrate. Nonetheless, tests by Dr. Mark Tallon demonstrated that—contrary to claims—CEE is actually less stable than creatine monohydrate during digestion.
Currently, there is no evidence that CEE actually works better than creatine monohydrate w/respect to gains in lean mass or strength.
Creatine Monohydrate
The most common, and best-studied form of supplemental creatine. See Paul’s review, “Creatine Monohydrate: The Bodybuilding Wonder Supplement?” for more information.
Creatine
A naturally-occurring, nitrogenous compound that – in the form of creatine phosphate – functions as a phosphagen: a storage form of phosphate for the production of ATP. Creatine can be consumed in the diet from animal protein, derived from the amino acids arginine, glycine and methionine, or taken in supplemental form.
Creatine supplements are taken by bodybuilders and other strength athletes to enhance lean body mass and strength. Creatine also has therapeutic potential, and has been used experimentally to treat neuromuscular disorders.

Adenosine Triphosphate
Also abbreviated as ATP. Adenosine triphosphate is a multifunctional nucleotide. It’s the major energy “currency” used to drive energy-consuming activities within cells and is also used in the synthesis of RNA and DNA. ATP supplements are marketed to enhance athletic performance, but the results of scientific studies have been equivocal.
