Just wanted to share my experience with this. I recently purchased what was supposed to be a tub of Iforce Max out and potassium nitrate caps. Well, to my surprise, the guy I ordered from shipped me a tub of hemavo2 max instead of max out... kind of a bummer... kind of cool. I figured why not give this stuff a shot? I usually mix most of my pump products using bulk powder, and I feel that my concoctions rival most of the other products out there (vasky, original hemavol, etc). I took one scoop of hemavo2 max with three caps of potassium nitrate, and it was goodnight, Irene. Longest lasting pump I have ever had. It was a three hour workout, and three hours after the workout I had incredible vascularity in the arms and shoulders. I am pretty depleted of glycogen, so I do not have much substrate to get a pump with, and my post workout carbs all came from vegetables such as cabbage. I believe that the hydromax glycerol may have been responsible, but I'm not sure.
Anyway.... Great pump, great product.
