I would disagree with powerlifting. IMO there are many world class/elite level powerlifters that I believe are natural. Of course at the same time there are some that compete in tested federations that are likely roided up, but the I really dislike the assumption that all are on something. They don't realize that there are extreme outliers out there that have both the genetics, leverages, high level responders to strength training and put in the work to get where they are at now. Also people don't realize that the popularity of powerlting (especially raw), have raised significantly (and at a young age) in the past 5+ years or so. So more people training to be strong = higher probability for more strong people.
