I'm pretty sure there was never an accusation of theft. Stimul was available from the corner pharmacy and was widely used by long-distance drivers. If it was was obtained from the team doctor - I presume you mean the swanny, Willy Voet - then it wouldn't have come as a such a surprise to all concerned.
Oh, and Kelly has never admitted he faked that test. It's still one of those mysteries, as far as he's concerned.
Apart from those quibbles, great story...
True he never tells the story himself it's more an old word of mouth story that's told about him.
As for the other details you are probably right as my memory and that of the people who told me would be fuzzy
