Reports have suggested Vieira used the drug to speed up the recovery from a thigh injury this summer.
He told L’Equipe: “I’m upset. This is not how I have managed 15 years of my career.
“I asked about several options for treatment. I received proposals from each and I judged which one would help me heal quickest. I never took anything.
“Once again, I am being given a trial for something that did not happen.
“I have done nothing banned or illegal and I can continue without problems looking into the mirror.”
