yeah man your right, it is because of the water and i dont doubt that the drinks do contain creatine and vitamin b in some form or another. but again, this is only going to help you dilute, and if you need creatine just eat meat and go and buy some vitamin b to color your piss yellow. i just got a bottle for cheap at save on. vitamin b or b complex both work. Id love to see the ingridents of some of those drinks lol
