I've been digging no-xplode in the absence of my AMP02. I feel that the no-xplode is equivalent if not better than AMP02 in some regards.
I'm going to try the plasma jet as well, very soon. As I'd much prefer tabs to a preworkout drink.
Big blast is good too, but I am cutting right now, so no go on that preworkout.
No Xplode has 400mg caffeine per serving. I'll pass lol.
If you are looking for an encapsulated pre workout in place of Amp02 check out Athletic Edge (AEN) PreSurge. My boy swears by it and the profile looks legit. I haven't tried it yet though.
