Chambers to reveal extent of cheating

10:15pm Thursday 15th May 2008

Dwain Chambers will confess to anti-doping chiefs on Friday that he was on an astonishing cocktail of seven banned drugs in 2003.

The British sprinter tested positive for the designer steroid THG in August of that year, and received a two-year ban.

But it has now been revealed he was also taking human growth hormone, the blood-boosting drug EPO, insulin, a testosterone/epitestosterone cream, a drug called modafinil used to promote alertness, and finally liothryonine, a synthetic form of thyroid hormone.

Chambers is meeting UK Sport's anti-doping chief John Scotton Friday as part of his campaign to come clean, and hope to gain a place in the British Olympic team.

He will provide Scott with an explosive letter written by his American drugs supplier Victor Conte detailing his actual drugs use.

Conte's letter has been obtained by BBC Sport, and he told the broadcaster: "This was the most sophisticated doping programme in the history of sport."

The programme was put together ahead of Chambers competing at the 2003 athletics World Championships, though he performed disappointingly at that event.

The 30-year-old's lawyer Nick Collins told BBC Sport: "I can confirm we are meeting John Scott.

"The intention is to open up a dialogue with UK Sport and to be as helpful as possible in their fight against doping. We will be taking the letter with us and discussing its contents."
