Arginine esters blend is an amino acid complex containing: arginine alpha-methoglucarate, arginine ketoizocapronate and arginine in free form. Arginine alfacetoglutarate (AAKG) glutaric acid and arginine, improving the bioavailability of arginine and enhancing the effect of each of its ingredients. Strengthens insulin and insulin-like effects. Arginine (an amino acid exogenous), is a component of protein in food synthesized in the human body in sizes not always sufficient, so it is necessary to deliver it in the form of synthetics. It participates in biosynthesis processes of agmatine, creatine and oxides of nitrogen. The use of arginine-containing supplements affects post-traumatic stress training (endurance, strength). After intensive effort, it intensifies the transfer of energy and building components and intensifies the renewal process. Applied at bedtime in combination with lysine and ornithine, it boosts growth hormone synthesis. Participates in the intracorporeal synthesis of creatine. Appreciably influences the increase of the volume of trained parts of muscles. The arginine esters blend is part of the formula of Xpand Xtreme Pump by Dymatize, available at www.muscle-zone.pl.
