Sonnen: I know for a fact that LeBron James takes EPO. We have one supplier

Former UFC and Bellator fighter, now analyst Chael Sonnen accused the famous basketball player LeBron James of doping.

“If the world understood what LeBron did... If you knew how performance enhancers work, then you would understand that it matters. We had the same supplier, I know exactly what he does.

Erythropoietin works, so LeBron takes it. EPO increases the number of red blood cells, and this increases endurance and you can play the whole match,” Sonnen said on the Flagrant podcast.
