Just so you know, there is a difference between testing positive for illegal steroids and testing positive for an illegal 'substance'. In many cases the illegal substances turn out to be a part of a legal product and fighters are cleared. Vitor, for example, made the same claim although he was charged and is serving his suspension. He did not use steroids, but other illegal substance. It may seem that it does not make a difference what you use, but we will never know if the fighter is telling the truth - he may have in fact inserted the illegal substance through a legal product. This is the reason there are different severities in charges for different offenses.
