UFC bantamweight champion Sean O'Malley went off on Conor McGregor, questioning multiple aspects of his character and abilities.
O’Malley’s tweets were prompted by laughing emoji response from McGregor, who replied to a video tweet with a clip of O’Malley claiming ostarine can be transferred through sweat. In the video, O’Malley claimed that was the reason he tested positive for trace amounts of the substance in the past.
