Creatine Ethyl Ester HCL (CEE) is creatine monohydrate with an ester attached. Esters are organic compounds that are formed by esterification - the reaction of carboxylic acid and alcohols. Due to the esterification of reatine, SCI-FIT?s® CEE will be absorbed more efficiently than traditional creatine monohydrate. This will allow the athlete to take a lower dose to experience similar if not better results.
