Chael Sonnen was a guest on Joe Rogan's podcast when he blurted out that Jon Jones failed his drug test because of two estrogen blockers. That's pretty significant, as Chael explains, because estrogen blockers are often used in addition to steroids to counteract the rise in estrogen that occurs when you raise your testosterone.
Gotta love dudes like Chael who absolutely have no filter. He seems like a guy that would immediately tell people the one thing you just told him not to tell anyone. Those are some of my favorite people.
