Picked up this pre workout via amazon. I got some sample packs to hold over until then. The blend is different on both. One is 7240mg and has 25mg of niacin, and the other is 7365mg and doesn't contain the niacin. How different are these going to be? The 7240mg blend is what comes in the tub. That's just dirty if my sample packs are going to be stronger than the tub I ordered lol.
EDIT: I am assuming the one I took is a current updated blend, and the other one is an older blend, but how old is it? and what's your opinion on the difference between the two regarding potency?
