Are you fuckin stupid cuz? The UFC let Vitor be on the juice among other fighters. It was 100% legal and Bispong knew it going into the fight. Also Bispong is the weakest MW champ of all time, and Vitor's timing wasn't lined up like it was for Bispong. Vitor beat Luke (Bispong did to win the belt), and beat up on Hendo (Bispong only title defense). I'm also pretty sure Vitor would have beat the piss out of GSP, instead of getting knocked the fuck out like Bispong did. Not to mention Vitor beat the breaks off Bispong to begin with. I'm also sure Vitor wouldn't have ducked the real contenders of MW like Bispong did, who defended against a 45 year old Hendo (not even ranked in top 10).
