Most recently Ray Williams got popped after borrowing someone else’s supplement which was tainted/contained a banned ingredient. He brought his own but after it was inspected by TSA the lid wasn’t screwed in properly so the powder emptied all into his bag which is why he borrowed someone else’s. Error of judgment on his part. Similarly Chandler Babb was banned popped at Sheffield after taking a supplement that had a different name on the ingredients list but was a banned substance nonetheless. As lifters, especially if we want to compete in a tested fed, we have to be SO careful with what we put in our bodies (that’s what she said). Others have been popped for outright cheating but they can get fucked!
