The rules are already established. If I have pumped myself full of anabolic steroids for years, and everyone know that I have done so, I will be banned from competition. They will not even waste the test on me. So if you have an individual who has been soaking in testosterone since birth, and they decide to cut off the testosterone so they can compete, they should be banned. It does not matter if that person is not on it now, that person was on it for years and the women that person is competing against were not.
