That's a good question , when I went to the website to see why they could sell the bars , that's what it said was the reason.
I went to the same website , Oneup mushroom bars and they now say they are 100% real and not just legal parts , but I still question that by what I got from them , it wasn't mushrooms like ones we would be used to , it was weak . My girlfriend claimed she felt nothing at all from 2 pieces and she isn't very big so it's weak .
