after weighing in for the fight on may 1, mayweather received an intravenous injection for the stated purpose of pre-bout re-hydration. the two iv infusions were administered at his home, amounted to 16% of the total average male blood quantity, and contained saline, multivitamins and vitamin c. the world anti-doping agency (wada) forbids such a large amount of fluids entering the body before competition as a preventive step against the possible masking of performance-enhancing drug use. bob bennett, the executive director of the nsac, stated that unless the iv was administered at a hospital, it needs to be cleared by filing a therapeutic-use exemption, and supporting documents through the nevada commission and authorized by the commission’s medical expert. the pacquiao camp had requested an injection of the anti-inflammatory toradol for pacquiao's injured shoulder before the fight, but was denied authorization by the nsac. usada authorized both injections, but the nsac was not informed of mayweather's iv until after the fight.
