Agmatine
Amatine is a metabolic byproduct of Arginine produced through a process called decarboxylation. Agmatine is basically Arginine with the carboxylic acid end removed. Agmatine produces the byproducts Guanidino-butyladehyde and the polyamines putruscene, spermine, and spermidine which are involved in cell growth. Agmatine modulates nitric oxide synthase, potentially to better workouts, performance, and recovery.* Agmatine may also provide some anti-oxidant support and improve endurance.*
