is pre workout just a caffeine and sugar shot? I mean I can just drink a redbull for that.

Not exactly sure what's in a Red bull, but a 200 mg caffeine tablet and some fruits will work perfectly and be much cheaper. You don't need some fancy concoction for a pre-workout. Point is to get caffeine and some carbs to get enough energy to be able to push hard in the gym.
