When lifting weights, muscle fibers are damaged and AA is released. Its release alters local chemistry, which supports a shift that favors anabolism.* The general anabolic cascade begins with the release of AA and is greatly amplified in the presence of more AA. This translates into supporting androgen receptors (increasing testosterone sensitivity), heightened IGF-1 signaling, greater vasodilation and even enhanced lipolysis.* The availability of AA appears to dictate how strongly this anabolic cascade will be stimulated with training.*
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.
