I know a cortisone injection is a steroid, but is not an anabolic steroid. However there are other items on the banned substances list and believe cortisone is one of them. Unfortunately I don't know enough about it, can't get a hold of my doc. I had one in my shoulder about a week ago and it's helped me alot. Possibility of random testing coming up in about 1 to 2 weeks. Anybody know anything about this? Do I need a T.U.E.?
