USADA posts test statistics on a quarterly basis, by sport and by athlete, as soon as possible following the completion of each calendar quarter.

In response to a high volume of interest in the testing statistics for the professional boxing event held on May 5, 2012 between Floyd Mayweather, Jr. and Miguel Cotto, the following is a summary of program information:

Both Mayweather and Cotto were tested a total of thirteen times each by USADA between March 7, 2012 and May 5, 2012, with eleven of the sample collections occurring with no advance notice leading up to the fight, and the final two sample collections occurring after the fight. For each athlete, USADA collected nine urine samples, and four blood samples. All samples collected by USADA were tested by a WADA-accredited lab in accordance with the WADA List of Prohibited Classes of Substances and Methods. All athletes tested by USADA are held to the standard of strict liability and are responsible for any prohibited substances that could be found in their body.

All urine samples were analyzed for EPO and by CIR, and all blood samples were tested for the presence of HGH. Collections were conducted using a balanced test distribution schedule, and with no allowances for black-out or cut-off dates.
