Olympic medalist Amir Khan has been banned from all sports for two years for doping.

Ostarine is a selective androgen receptor modulator that, according to UKAD, is intended to have similar effects to testosterone. Khan, who announced his retirement three months after the fight, admitted to breaking anti-doping rules but claimed he had not ingested the substance on purpose.
Following a hearing in January, an independent panel agreed. His prohibition will end on April 5, 2024. In response to the announcement, Khan told Sky News in London that he has never cheated in my life. 
As my performance against Kell Brook demonstrated, I lost the fight. It would be different if I went in there and knocked Kell Brook out, he explained. Khan, 36, expressed surprise that he has been banned now that he has retired from boxing.
If they ban me, I’m out, he said. I’m already retired. Khan, one of the best British boxers of his generation, retired with a 34-6 record, though his result in the fight against Brook was disqualified by an independent panel.
It’s a sad end to a career that began at the age of 17 with a gold medal at the 2003 Junior Olympics and a silver medal at the 2004 Athens Olympics.

Khan lost world title fights against Danny Garcia, Canelo Alvarez, and Terence Crawford later in his career. Khan has appeared on reality TV shows in recent years and is set to appear on I’m A Celebrity… South Africa later this month.
