Either that or BAC has is it pretty cheap in powder form. I don't think theres any reason to buy something just for pumps. If there was a study proving NO2 builds a substantial amount of lbm, I might try it, but I get massive pumps just by lifting heavy weights. Pumps make your feel good about your body because of the increased blood flow which cause increased blood flow which just causes a flower look to your muscles. Thats all they do however, in my opinion.
