Before his foot injury, LeBron James was still dominating the NBA in his 20th season in the league at age 38.

Former MMA fighter Chael Sonnen has a theory as to why, alleging that James takes performance-enhancing drugs.

Sonnen claims that he and James are on «the same type of drugs,» adding that he and golfer Tiger Woods are on «the big three» of EPO (erythropoietin), growth hormone, and testosterone, a combination of enhancers he called the «Lance Armstrong Diet».

«I know exactly what [James is] doing,» Sonnen said on the «Flagrant» podcast.

Sonnen claims that Woods is the «only golfer» to use the cycle and provided «the reason» James allegedly takes it.

«The EPO matters; it’s the reason LeBron takes it. It matters,» Sonnen said. «EPO increases your red blood cells, giving you stamina so you can play throughout the game. You can shoot the fourth quarter like you did in the fourth minute. He’s the king of performance enhancers.»

Armstrong took performance enhancers throughout his cycling career, especially EPO, and it cost him his seven Tour de France titles.

Of course, we only have Sonnen’s word without evidence.

James has never failed a drug test in his career, and Woods has never been tested for steroid use.
