British Olympic Silver Medalist Ujah Suspended for Alleged Doping

PARIS - British sprinter CJ Ujah, who won an Olympic silver medal in the 4x100m relay in Tokyo, was Thursday suspended for an alleged anti-doping breach, the Athletics Integrity Unit (AIU) announced.

If the case is proven, then 27-year-old Ujah and the British team will be stripped of the silver they won behind Italy in Japan. The AIU said that Ujah was found to have "presence/use of prohibited substances ostarine and S-23, which are selective androgen receptor modulators (SARM).” They are substances commonly used to build muscle.
