Possible? Anything is possible. Highly highly unlikely though. I have been competing as a natural for man years, and have pro status in two natural orgs. I have been coaching natural competitors for years as well, and have seen some absolute freaks at the upper levels of the sport. Could the best push the pack at a smaller pro card producing NPC show? Yes, but very very few could do it. Even a guy on TRT only, has a pretty large advantage over a true natty, because the TRT guy does not have to deal with the down regulation of testosterone as body fat levels get extreme. Trust me when I tell you it is very had to bring a competitive package to hang with the big boys when that happens. The way a natty could do it is be able to carry enough size, yet get absolute inside out lean, and hope that the judges favor leanness over mass in the show they are competing in. The other issue is, you never really know who is natty. I know all of my guys are because it is a conversation we have right up front during onboarding, but I know some coaches out there that will have you / let you use and still compete as a natty. It is shameful. That said, the tests really are easy to beat if you wanted to. You'd be surprised how many guys get found out for using after the show, when the urinalysis comes back. The sport is built on good faith. I went up against a guy at a pro show that beat me, and ended up being on after the fact, and they stripped him and banned him, and awarded me the title lol. It was a weird one because on one hand, he shouldn't have been there to begin with, but also weird to be like oh here is a pro win that you didn't actually win.
