Interesting. I will look it up :) Im trying Agmatine right now, I have a memory that a couple years ago I took Agmatine as a pump in the gym supplement, having no idea it did anything else. Under that time I was feeling so stress free and my stutter almost dissapered. A couple months ago I stumbled upon Agmatine as a "Nootropic" and it just hit me, wow, maybe that was why I was almost "cured" and life felt so good at that time.
