The UFC’s partnership with the United States Anti-Doping Agency nears its end, with a scheduled termination as soon as the calendar flips from 2023 to 2024.
In 2023, USADA tested 739 mixed martial artists a combined 4,231 times. While many athletes were randomly tested less than 10 times, some were tested two dozen – and some others, even more. The totals represented 48 more tests and 14 more athletes than in 2022.
With testing data available on USADA’s official website, here are the 12 fighters tested the most from Jan. 1 to Dec. 26, 2023.
Note: There may have been additional data from Dec. 27-31 that has not yet been updated in the USADA database.
