You'll have to provide a link to that, because I've never heard Marquez say that he would demand a PED test from Pac....... .......now you might be thinking of what Richard Shafaer, head of GBP said on the matter when the Mayweather-Pac negotiations were falling apart......Shafaer said back then that they would require a PED test from Manny against anyone of GBP fighters...... That was Shafaer who wanted to make the Mayweather fight happen talking, Marquez that I know of has yet to make a statement on the matter.
