CJ Ujah: Team GB’s relay team face being STRIPPED of medals after sprinter’s B sample tests positive

British sprinter CJ Ujah’s B sample from the Tokyo Olympics has tested positive for banned substances, the International Testing Agency (ITA) has announced.

Ujah provided the sample on August 6, the ITA said, the same day that he was part of the British team which won silver in the men’s 4×100 metres relay.

The agency said now the B sample had confirmed the result of his A sample, his case had been referred to the Court of Arbitration’s Anti-Doping Division (CAS ADD).

The court division will consider the finding of an anti-doping rule violation and the disqualification of the British relay team, the ITA said.

Ujah was provisionally suspended following the result of the A sample last month and released a statement on August 14 saying he was ‘shocked and devastated’ by the outcome of the test.

He added: ‘To be absolutely clear, I am not a cheat and I have never and would never knowingly take a banned substance.

‘I love my sport and I know my responsibilities both as an athlete and as a team-mate.’

Ostarine is a Selective Androgen Receptor Modulator (SARM) – a type of therapeutic compound used for stimulating tissue growth like muscle and bone. 

The substance is not approved for human consumption in any country and is prohibited at all times in sport by WADA. 

There have been a rising number of positive tests involved ostarine and other SARMs in recent years, with athletes likely to obtain the substance from black market channels.

Ostarine can be found in other products – but only illegal ones, and a doctor will never prescribe a treatment or medication that contains it.

Some dietary supplements can contain SARMs such as ostarine and are sold as ‘legal steroids’ or ‘research only’ chemicals, according to USADA.

There is interest in ostarine to treat a number of muscle-wasting diseases, including cancer, osteoporosis and hypogonadism. 


Ujah’s sample returned an adverse analytical finding (AAF) for the prohibited substances ostarine and S-23, the ITA said. These substances are selective androgen receptor modulators (SARMs) and help with building muscle.

If the case against Ujah is proven, the British relay quartet, also including Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake, are likely to be stripped of their silver medals.

The possible forfeiture of the medals will be considered first, before the Athletics Integrity Unit (AIU) follows up to consider any sanction beyond the Games for Ujah. 

As Sportsmail revealed last month, Ujah’s lawyers are expected to argue that the banned substances were not listed as components in a supplement he took ahead of the final.

Ujah denied being a ‘cheat’ by insisting he would never knowingly take a banned substance, but his case has now been handed over to the CAS after his B sample also came back positive
