Sir Mo Farah Releases Statement After Coach Alberto Salazar Investigation Leaks

Sir Mo Farah has insisted he is a "clean athlete" in response to allegations made about his coach, Alberto Salazar, and the potential breach of doping regulations.

A leaked U.S. Anti-Doping Agency report picked up by the Sunday Times (h/t BBC Sport) claimed Salazar "abused prescription medicines and used prohibited drug infusions to boost testosterone levels and the performance of his runners."

However, Farah took to social media on Sunday to deny any wrongdoing:

A BBC Panorama programme had previously suggested that athletes had been using banned substances at Salazar's Nike Oregon Project, and the coach has been under investigation since.

According to the new information attained by the Sunday Times, Farah is one of a number of athletes who were prescribed medication that could have had harmful side effects.

There was no medical reason for the athletes taking the substance, a chemical called L-carnitine, which is said to increase testosterone levels and enhance recovery.

The Sunday Times also reported that Salazar informed disgraced former cyclist Lance Armstrong, who admitted to taking banned substances himself, about the effects of the chemical. "Lance, call me ASAP!" the coach is said to have emailed to Armstrong. "We have tested and it's amazing."

Matt Lawton of the Daily Mail provided more information about the report and suggested UK Athletics has previously raised concerns about some medicines Farah was using:

As BBC Sport noted, Salazar has insisted in the past that the use of L-carnitine has always been in line with the World Anti-Doping Code regulations.

Farah has established himself as one of the finest British athletes of all time in recent years, and it was confirmed on New Year's Eve that he would be knighted due to his incredible sporting success.

The 33-year-old starred on the track at the 2012 Olympic Games in London, winning gold in the 5,000-metre and 10,000-metre distances.

In Rio de Janeiro, he repeated the double to cement his status as a legendary distance runner. Farah has also won World Championship gold on five occasions.
