USN Creatine X4 provides a blend of the most prominent creatine compounds of our times, incorporating different mechanisms of uptake to help promote efficacy. It includes water-soluble derivatives, of which creatine nitrate and hydrochloride (HCl) are ulta-soluble in water and therefore regarded as fairly fast absorbing. It further includes the super-concentrated creatine monohydrate. Creatine Ethyl Ester HCl is a fat soluble form of creatine. Apart from muscle mass supporting amino acids and magnesium, Beta-alanine, Alpha-lipoic acid and BioPerine® have been added to the formulation to help promote the transfer of both nitrogen and nutrients.
