Simply put; because it works, and works well. If you are one of people who chug down their pre-workout in a matter of seconds, then this a superb option for you. But if you're more like me, and enjoy sipping it down on the way to the gym, then you may want to try something else. I've trevulan recently finished a tub of C4 Extreme which I really enjoyed, both in taste and results. Platinum Pre could also be a superb option for someone who is already supplementing with Creatine monohydrate independently, and doesn't need any more from their pre-workout.
