LONDON (AFP) - Dwain Chambers was taking a cocktail of seven banned drugs when he was caught doping, the disgraced British sprinter told UK Sport on Friday as he moved closer to a court action aimed at securing a place in the Beijing Olympics.
Chambers received a two-year ban as a result of a positive test for the designer steriod THG in 2003.
But according to a letter written by his drugs supplier, Victor Conte, 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 liothryonine, a synthetic form of thyroid hormone.
Conte is the president of the Bay Area Laboratory Co-operative (BALCO), the California-based company at the centre of an ongoing investigation into steroids distribution in athletics and baseball that has already resulted in sprinter Marion Jones being sent to jail and may have a similar outcome in the case of baseball star Barry Bonds.
Conte's letter was handed over to UK Sport's anti-doping chief John Scott on Friday in a move that Chambers hopes will help to demonstrate that he has repented over his use of banned substances and wants to help clean up the sport.
Scott would not divulge what his meeting with Chambers had covered.
"We welcome the fact that Dwain has come in to speak with us," he said in a statement. "We had a constructive and positive meeting and see it very much as the starting point of what we hope will be an ongoing relationship.
"This was a private meeting and it will not assist either party to go into any great detail of what was discussed at this stage."
Chambers, 30, has re-established himself as Britain's best sprinter since launching a second comeback in January, notably claiming the 60m silver at the World Indoor Championships earlier this year.
But a ban by the promoters of most of Europe's top meetings has left him unable to earn a living from athletics and he recently had a trial with rugby league side Castleford, who have decided not to take him on.
Chambers has been contemplating legal action to overturn the British Olympics Association's policy of preventing athletes who have committed doping offences from representing Britain in the Olympic Games.
Such a move would be fraught with financial risk for the athlete but his lawyer, Nick Collins, indicated Friday that Chambers was intending to go down that route by confirming that his client intended to insist on being allowed to take part in Britain's Olympic trials in July.
"We can confirm that Dwain Chambers will be taking proceedings to secure his eligibility/participation in the Olympic and National trials in Birmingham from 11-13 July," the lawyer said in a statement.
British shot-putter Carl Myerscough, who served a two-year ban for taking anabolic steroids, is also considering a legal challenge to the policy of the BOA, which has said it will "vigorously contest" any such action, leaving the plaintiffs liable for huge legal costs if their appeals fail.
The BOA rule has been in place since 1992 and is at odds with the policy of organisations like the International Association of Athletics Federations (IAAF), which take the view that athletes found guilty of doping can return to all competitions once they have served their bans.
Former World Anti-Doping Agency president Dick Pound are among those who have suggested that the BOA's stance would not stand up to a challenge through the courts of most countries or through the Court of Arbitration for Sport (CAS).
