I picked up three bottles of AI Sports Agmatine recently because I it was a good deal and I was ordering some protein. I had been wanting to try agmatine to see if it lived up to the hype, regardless I like much of Dinoiii's advice and knew there was more to this product than just a pump. Anyway, I took 1g (4 caps) 1 hour before the gym tonight and I was working chest and tris. I was not too impressed early on, though I attribute this to lots of food in my stomach which slowed down the absorption of agmatine. About thirty minutes into my workout and I was getting insane pumps, by the end I could not lock out during tricep work because of the pump. Glad I got three bottles of this stuff to see how it runs long term. I definitely recommend to try out AI Sports Agmatine, I know some users of other brands have had hit and miss results, hopefully those of you who try AI Sports will find the same quality that I did.
