Conor McGregor responds to accusation he took performance-enhancing drugs

Conor McGregor has hit back against claims he used performance-enhancing drugs, following a long hiatus since his injury in a trilogy fight with Dustin Poirier. The MMA star, who hasn't fought since breaking his leg five years ago, is set to return this summer against Max Holloway. This comeback comes amid scrutiny and skepticism about his past performance, but McGregor insists he's clean and ready to prove it in the octagon. The implications of these accusations could affect not just his reputation but also the perception of the entire sport of MMA.
