Shane Mosely and Floyd Mayweather Steroid Accusations Against Manny Pacquiao

  • Tweet

Manny Pacquiao has repeatedly been accused of using anabolic steroids by his opponents and his many detractors. Floyd Mayweather Jr. and his good friend rapper Curtis “50 Cent” Jackson have taken to Twitter to accuse Pacquiao of steroid use.

“50 Cent” had accused boxer Manny Pacquiao of using anabolic steroids in a series of messages posted on Twitter in March while hanging out with Floyd Mayweather to promote his new film, “Things Fall Apart”, at the Miami Film Festival.

A much anticipated “super fight” between Mayweather and Pacquiao was originally delayed last year after Mayweather insisted on “Olympic-style” steroid testing. Mayweather has repeatedly avoided fighting with Pacquiao often citing some version of his steroid accusations as his reason.

This month, an article on reported that a former sparring partner of Pacquiao claimed to have injected him with anabolic steroids. The posting didn’t attract much attention until Shane Mosely, a boxer with his own well-publicized issues with performance-enhancing drugs, decided to bring attention to it with his tweets:

Mayweather quickly followed on Twitter by encouraging his 1.2 million readers to read the steroids accusations:

The original article on has since been removed but it caused enough controversy to prompt Pacquiao to respond with a formal statement. Pacquiao claimed his success was due to hard work and a “belief in God” that had nothing to do with anabolic steroids:

An anonymous post on an internet forum claims an unidentified former Filipino sparring partner injected me with steroids before my fight with Oscar de la Hoya and in subsequent fights. This is completely false, totally fabricated, and, not surprisingly, leveled by someone who will not even identify himself. I did not even have a Filipino sparring partner during my training for the fight against De La Hoya or for any fight since then.

I have never taken steroids, HGH, or any banned performance-enhancing drug. Period. My success in the ring is due to hard work, belief in God, and the support of my fans. Like every boxer, I am required to take drug tests in connection with every professional fight in the United States. I have passed every one, including my fight against De la Hoya and my most recent victory against Shane Mosley.

I will fight to protect my hard-earned good name and reputation.

Boxing fans are becoming increasingly impatient with the trash talk with repeated accusations involving the use of steroids. They simply want to see Floyd Mayweather and Manny Pacquiao settle the dispute in the ring.
