Some of the biggest and brightest stars of UFC maybe bar GSP have ALL been popped for steroids or PEDs

Anderson Silva
Brock Lesnar
Jon Jones
Cung Le
Rousimar Palhares
Stephan Bonnar
Chris Leben
Alistair Overeem
Sean Sherk
Vitor Belfort
Nate Marquardt
Tim Sylvia
Josh Barnett
Donald Cerrone
Thiago Alves
Josh Burkman
Antonio Silva


and yet it seems like the UFC views PEDs like the way the NFL does, somebody gets popped and although Dana White will rant about it once or twice other than a short ban nothing happens and most of these guys are welcomed back with open arms....especially Jon Jones.
