That's the same shit as the other ones. It still contains caffeine.
Haven't touched an energy drink for more than a year. I used to take 2 day and some times throw down an ephedrine tablet with it. Had to get a stent in the widow maker artery. Don't know if that's what caused it. I doubt it. But I did abuse the caffeine and ephedrine combo for years.
