Yes this is a fact okay.. Big E was a youtube sensation and competed in multiple to dozens of bodybuilding competitions a year and then competed in College football while doing bodybuilding (for which he was also tested each season). When you juice directly, it can stay in your system from anywhere between 2 months and 18 months depending on how strong the substance is and how it worked with your body. Do the math.. He would've failed numerous drug tests because all of those competitions and all of his record attempts are tested. You don't become a YouTube sensation or a record holding bodybuilder by cheating..you know this for a fact? source please? You mean to tell me this guy doesn't juice at all?
As for a source, use Google and type in "Ettore Ewen failed drug test" you won't see anything.. you just have to use logic.
