regular red bull - might as well take a tbsp. of table sugar
diet red bull - ton of "great" chemicals , which are wonderful at giving you long term health problems
Crazy shit. If you want taurine, buy taurine; if you want sugar, buy sugar. Why pay some company day after day to add water for you and give you a can to throw away?
too much hype around red bull.....tastes good, but shouldn't be a staple in a routine (and is a bit expensive). I've had better luck on caffeine pills and simple carbs for extra energy
