This brings up the other grey area, it is known to be a PED but allowed out of comp, could he take shit loads in the months prior to Rio with the purpose of takinh his training to the 'next level', stopped just before race but still had too much in his system and triggered the positive.
No - pred doesn't work that way.
First of all, coming off of pred sucks - like a bad hangover. Fatigue, aches. Basically the inverse of how great you felt while on it. Imagine going cold turkey on coffee, starting a few days before your race, only 10 times as bad. I would NEVER want to train on pred, and then stop taking it right before the race.
And the "gains" you observed while training on it are phantom gains. I've had to take several five day bursts of pred over the years, and I've learned that I have to be very careful about controlling my workouts during that time. It's very easy to overdo stuff because I feel like a superhero, and then it catches up with me and I'm in a hole or injured when I come off the pred.
Pred also has all sorts of nasty side effects - weight gain, bone density loss, immunosuppression. And I'm told that the boost that you see from it when you use for a few days fades if you're on it long term. [if you're on it long term, you also have to taper down on it rather than quit it cold turkey.]
Honestly, I only take pred during training as a last resort, and that's not just because I'm ethical. Every time I do a burst of it, I feel like I'm risking my training, not aiding it. I really can't see any benefit from training on it, and then coming off of it to race.
The only way to see performance benefit from pred, IMHO, is to train without it and then start taking it a day or two before your race.
Regarding TUEs and pred - as I think about it, I could see a case for a TUE for someone who is on a long term maintenance dose of pred for Chrohns, allergies, etc. In that case, I don't see any benefit to them from continuing their maintenance dose, and there would be significant health risk to them if they stopped.
But absolutely no TUEs for someone who experiences an autoimmune or asthma or allergy flare a few days before their race, and wants to go on pred. Tough luck, but you need to sit it out.
