“Truth finally came out and I was vindicated,” says Manny Pacquiao after reports that Floyd Mayweather had taken a banned intravenous injection before their May fight.

The Filipino boxer had previously settled a defamation suit with Mayweather for an undisclosed sum after Mayweather's camp alluded on several occasions that Pacquiao had used performance enhancing drugs.

Now it's Mayweather who is under the spotlight after a report on SB Nation stated that Mayweather had received a retroactive therapeutic use exemption (TUE) after IVs containing multi-vitamins and Vitamin C were discovered at his home by United States Anti-Doping Agency (USADA) agents following the weigh-in.

USADA was commissioned to oversee random pre-fight testing for their May 2 fight, which Mayweather won by unanimous decision.

“Truth finally came out and I was vindicated,” Pacquiao texted to PhilStar’s Abac Cordero.

Though the substances are not banned by the World Anti-Doping Agency (WADA), which sets the standards for anti-doping testing, intravenous therapy "of more than 50 mL per 6 hour period except for those legitimately received in the course of hospital admissions, surgical procedures or clinical investigations" is on WADA's “Prohibited Substances and Methods List.”

“Mayweather camp used to accused (sic) me of using PED. Now, look at what happened. I hope Floyd Mayweather would learn a good lesson out of it," Pacquiao continues.
