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.
