My opinion, for what it's worth (not much) . . . Since the guy spoke up, he's sunk. DQ unless and until he stops using. But on the other hand . . . that's too bad because it has been speculated that MOST Masters age group athletes are using something for which they could be banned. No TUEs. No excuses. But they keep their mouths shut and (for the most part) they only enter races where they don't expect to be tested. They compete without anyone being the wiser.

I suspect that the vast majority of age group "dopers" are no-ill-intent, "harmless" dopers. They are taking prescription medications that bring them soundly within the "normal" range for someone who is healthy and not doping. Nothing that makes them into a "Superman." Just enough to allow them to compete within the "normal" range for their age and gender. Still, the rules are the rules. And the rules put them in the same category as the "to the gills" doper who wants to regain his or her performance from when they were 15 years younger. Until he gets a TUE, your guy should be out.
