Poland’s Krzysztof Glowacki , a former WBO champion, has been suspended from all sports for four years after he was found guilty of using an anabolic steroid, U.K. Anti-Doping (UKAD) said Tuesday. According to Reuters , Glowacki, 37, failed a UKAD-administered drug test following his fourth-round TKO loss to Richard Riakporhe on Jan. 21, 2023 in Manchester, England. His urine sample contained Boldenone, an anabolic androgenic steroid on the World Anti-Doping Agency’s (WADA) list of prohibited substances. Glowacki (32-4, 20 KOs) denied knowingly taking a prohibited substance when he received a provisional suspension last April.
