What are you looking for it to do? Give a caffeine high? I think Napalm is a better product than No-Xplode, but I was more commenting on the effect you were looking for.
No Xplode is probably very similar to Superpump. I found Napalm to be a more subtle energy but one that lasted longer as well.
Do you drink much Coffee Poopoo? I hate coffee and never drink, when I have one of these PWO shakes, they work VERY well for me as I am not as desensitised to caffeine.
