First of all it's not the "Thai version of Red Bull". It's the original Kratin Daeng. Go read up some corporate history and find out how the Austrian Redbull we have here in western countries came about. And you are dumb...the "cans in the US" are not in anyway stronger than Kratin Daeng. If anything it's either the same or lighter coz it's been diluted. As for ingredients and amount of caffein, both are pretty much the same. Difference is I'm not sure if Kratin Daeng has Taurine(can't remember) and Kartin Daeng has 2 or 3 kinds of B vitamins whereas Redbull only has one. I dunno if it's B6 or 12 or watever.
