Britain's 4x100-meter relay team has been stripped of its silver medal from the Tokyo Olympics after C.J. Ujah’s doping violation was confirmed by the Court of Arbitration for Sport. Ujah’s sample taken in Japan in August, 2021, contained the prohibited substances ostarine and S-23, which are selective androgen receptor modulators (SARM) and help with building muscle. Ujah did not challenge the anti-doping rule violation, but CAS said he claimed to have not knowingly or intentionally doped and that “the source of the prohibited substances could have been the ingestion of a contaminated supplement."
