Again, a Retroactive TUE means that he is in compliance and Retroactive TUE is within WADA rules.
Like most substances and methods on the WADA Prohibited List, the use of IVs in this manner is prohibited without a TUE. When an athlete has an approved TUE, as in the case of Mr. Mayweather, who received a retroactive TUE for his use of an IV containing saline and vitamins, it is not a violation of the WADA rules to use the substance or method. Retroactive TUEs are a standard part of the WADA International Standard for The****utic Use Exemptions (ISTUE).
