Serum Matrix Pump, is a component of the two forms of arginine: Alpha-ketoglutarate arginine and arginine HCl, the so-called enhancer of muscle pump effect. Arginine is an essential amino acid, it is a component of dietary proteins synthesized in the human body in quantities not always necessary, hence it is necessary to deliver it in the synthetic form. It takes part in the biosynthesis of agmatine, creatine and nitrogen oxides. The use of supplements containing arginine affects pre-workout with the increase of the functional capacity (strength, power). Ingested after considerable effort intensifies the transfer of energy and building compounds and intensifies the process of renewal. Used at bedtime in combination with lysine and ornithine enhances the synthesis of growth hormone. Participates in the intracorporeal synthesis of creatine. Arginine (as a precursor of ornithine) is involved in the urea cycle, increases the flow of blood in the circulatory system increases sexual potency (in a short time after application).
