Good stuff. This Agmatine worked well. I would take a dose about a hour before my workout and it helped a lot. I noticed a lot of effects. The pumps were great and it also gave me a bit of vascularity. The agmatine gave me an edge in the gym. Could go for longer during my workout and could squeeze out a extra rep or two. I felt it enhanced my mind muscle connection. I do not think this is of Agmapure quality but still a great product. I would recommend this supplement to others.
