I purchased a Yoohoo today and saw a new label on it “99% caffeine free”.  If this implies that it’s 1% caffeine that’s 4.5 mL of caffeine or 5500 mg of caffeine or the equivalent of 68 Red Bulls or 27 caffeine tablets, in other words just enough to kill an adult.  Should this bear fruit, Yoohoo may become my poison of choice.
