Agmatine, also known as (4-aminobutyl)guanidine, is a aminoguanidine that is synthesized by decarboxylation of the amino acid Arginine. Originally discovered in 1910 by Albrecht Kossel, Agmatine has been shown to exert modulatory action at multiple molecular targets, notably: neurotransmitter systems, key ion channels, nitric oxide (NO) synthesis and polyamine metabolism, thus providing basis for further research into potential applications.* Pure Agmatine Sulfate Powder.
