Manny Pacquaio sued Mayweather for falsely accusing him of taking steroids before his boxing fights. The case has yet to be decided by the Courts of the United States. I am positive that Manny Pacquaio does not use steroids but I wonder if he does take sports supplements to make him strong. If he does well I guess Mayweather takes them, too as well as many other boxers. Well, the truth will come out, soon.
