That is a lot of caffeine.
Good pumps, but I don't like the caffeine.
When I add the NO Explode, it's too much. I'w wired and I can't relax PWO. I regret my purchase.
I would not buy it again, but I'll continue to check out other NO supps that do not contain stimulants and even plain old Arginine AKG.
I think stimulants help sell it. I mean, you can really feel it "working" when you're heart is beating like crazy.
