British boxer Adam Machaj has received a four-year suspension after an anti-doping violation was revealed on reality television show SAS: Who Dares Wins.
The 33-year-old, who is now retired from professional boxing, appeared on the TV show in January 2018.
In the episode, Machaj was questioned about Clomid tablets which were found in his possession.
A day after the broadcast, Machaj’s representative approached UK Anti-Doping (UKAD) for information about how to apply for a retroactive Therapeutic Use Exemption (TUE) for clomifene.
The retroactive TUE process revealed that Machaj had been taking other banned substances, including anastrozole and testosterone, and had lied about taking them when renewing his British Boxing Board of Control license and in pre-contest medical assessments.
UKAD issued Machaj with a notice of charge on December 2.
Machaj admitted the charges, but disputed the sanction by claiming that he took the substances to deal with a medical condition.
He applied for a retroactive TUE three times, but his applications were unsuccessful.
The case was referred to the National Anti-Doping Panel and heard by an independent tribunal.
Machaj was given a four-year suspension, starting on November 14 2018 and finishing on November 13 2022.
His results in all contests since September 2015 were also disqualified.
"This case was unusual in that it came to light in such a public way," said UKAD deputy director of operations Hamish Coffey.
"It is important that athletes and the general public see that UKAD is taking action to remove those who take banned substances from sport and the sporting environment, to protect the integrity of sport and places such as training centres and gyms.
"The TUE system exists to ensure that those with legitimate medical conditions can apply for permission to use medications, which are otherwise banned.
"This case shows the process for applying for a TUE is thorough and robust, and that a very strict criteria must be satisfied before a TUE is granted."
Machaj completed 11 professional fights during his career, winning nine and losing two.
