Listen, there isn't anything else out there that compares to premax. It's a macro-supplement: it provides the macros you need to performs at 100%, along with a nice antioxidant and testosterone-support formula (carnitine); it provides these in the most effective, efficient forms of these macros possible in clinically proven dosages. It's quite unlike other pre-workout supplements which provide non-essential nutrients like arginine, or stims, or just carbs like Accelerade/Gatorade.
If your goal is performance, be it a PR in deadlift, a world record in downhill skiing, or winning an MMA match, or practicing for any of those, PreMax will be your best friend.
My opinion? If you don't see the point of PreMax, your shouldn't bother using it. (In other words, if you're too dumb to get it, well, it ain't gonna help stupid anyway, so stay away).
