Mayweather also applied for, and was given, a therapeutic use exemption (TUE) for rehydration purposes after the May 1 weigh-in. He took two separate mixes. The first was a mixture of 250 ml of saline and multi-vitamins. The second was a 500 ml mixuture of saline and Vitamin C. He was urine tested both before and after taking the solutions.

Nevada rules permit the mixes that Mayweather took, but because USADA was overseeing the testing he applied for and was granted the TUE for them.

All tests came back negative.
