5/5
I've used 3 different brands of bulk powder Ag before, plus numerous preWOs with non-prop blends containing Ag, & this seems to be the best stuff I've used to date - pumps come on immediately after the 45-90 min delayed-release caps have dissolved & any kind of repetitive motion occurs. I mean I walk into the gym & start warming my upper body on the cable tower & veins are busting out of my arms like I finished a serious arm day. Freaky, & awesome.
5/5 - best agmatine I've had the pleasure to use, & would highly recommend if you're looking for 500mg caps to augment other preWO formulas or just for a standalone great pump.
