Arginine Alpha-Ketoglutarate (AAKG) It's an amino acid compound that's been shown to help increase muscular 'pump' and vascularity as well as the delivery of blood, oxygen, and nutrients to the working muscles.
L-arginine HCL attaches the amino acid to hydrogen chloride (HCL). ... Hydrogen chloride also makes L-arginine better absorbed by the body.
l-Arginine ethyl ester or ethyl alginate is an alternative supplement form of the conditionally essential amino acid arginine bound to an ethyl ester. Esters are organic compounds formed by esterification – the reaction of carboxylic acid and alcohols.
Citrulline ethyl ester - formed in the esterification process (of alcohol on the amino acid citrulline), facilitating the bioavailability of citrulline and reducing its consumed dose. Citrulline is an amino acid that does not build endogenous proteins. It is a precursor to arginine, processed to form nitrous oxide, and supports the metabolism occurring with the participation of arginine
