I dunno how ppl think Badr juices, he was always kinda skinny and after he lost to alistair he went on an insane strength and conditioning workout routine, since he was so skinny he gained muscle and looked more cut up, doesn't mean he roided. In fact I think he's one of the fighters who never roided.
