Ive been around the block and i would say performance wise its going to be one of the best. Endurance is insane at only 2 scoops. Like others said it hardly seems like it has any stims in it but hell caffeine tabs are cheap if you want stims. I prefer this over arginine based products as well since i can use this without getting mouth ulcers.
ive heard the arginine and mouth sores thing before.... cant remember why it sets it off though
i dont doubt that performance wise its good, i mean that is what its based for, but most of us are bodybuilders and not performance athletes, now it should be targeted at athletes such as MMA football crossfit, boxing thatd be awesome.....
but bodybuilders need intensity and power, and at 2scoops its easily going to be 1.50$/workout which is above my idea of cost effective,
just saying but im a cheap ass so.....
