Why on earth would a UFC fighter not do juice; why on earth would anyone think they shouldn't. They juice pitbulls and chickens for the same shit and it's considered awesome because it makes for some crazier shit in there. I used to have a guy I knew bring in the gaffs they attached to the chicken feet explaining to me that with these, when the action really gets good, you get bodyparts flying off and shit...legs, wings, heads. Just like throwing them into a blender.
