For decades, Manny Pacquiao has faced questions about potential by using performance enhancing drugs. His eternal rival, Juan Manuel Marquez, largely avoided this until recently when he aligned himself with strength and conditioning coach Memo Hernandez and packed about the muscle because of their fourth fight that occurred earlier this Dec. 8, 2012, for the MGM Grand Garden Arena in Nevada, Nevada.
Once Marquez bumped out Pacquiao inside sixth round, completely separating "Pacman" from his senses, the shock quickly turned into more questions.
Where did that strength instantly come from?
Well, fortunately that based on BoxingScene.com, both fighters passed their post-fight drug tests. Does which means that they're both clean? Certainly not, but anyway it offers a way of measuring confidence that the classic battle all of us witnessed in "Las vegas" isn't tainted by steroids.
