the trick is to compete in a show that is not tested if you are not able to pass a test.

I know too many people who do this and shove it down peoples throat that if they did this or that they would look like this or that, b/c they compete at natural shows they must not be on anything
Just find an organization that does not discriminate against your choices and then you can do the show stress free.
You'll find more people like you and have more in common with anyways
