International Tennis Integrity Agency (ITIA) said on Wednesday. Moore, ranked 83rd in the world, provided her sample while competing in a WTA 250 event in Bogota, Colombia -- where she lost in the final -- and the AITA said her 'A' sample contained Nandrolone metabolites and Boldenone. Both substances are on the 2022 World Anti-Doping Agency (WADA) Prohibited List. Her provisional suspension, backdated from May 27, will make her ineligible to compete in or even attend sanctioned events. "I have never knowingly taken a banned substance in my career. I am investigating how the positive result could have occurred and look forward to proving that I am a clean athlete," Moore wrote on Twitter.
