The Oh Yeah bars only have 6-8% calcium. Something is VERY WRONG THERE! The Combat bars have 22% which is what you would expect at 60-63g bars. I'd stay far away from the Oh Yeah for now. The Muscletech bars can't ingredients can't be found anywhere. There not selling them yet I guess. They must of started showing them at the Olympia. There is no added calcium so that is not what the problem is.
