Superpump is a good product. It has around 60 mg's of caffeine per serving, which is lower than the caffeine content of most of the other pre-workout formulas on the market. Gaspari has the tastes down on their formulas. Other products (like NO3 Overload by CMI and Armageddeon by Starchem) work really well, but they are higher in caffeine and they have stronger tastes. It all depends on what you want out of your pre-workout.
Way more caffeine than that in the super pump(from what I hear) . Great product but I don't like the Super Dumps that come with it. Armageddon is good, but I like the stone dragon better. Best pre workout ever is RPM by Applied Nutraceuticals.
