Dwain Chambers was taking a cocktail of seven banned drugs when he was caught doping in 2003, the disgraced British sprinter has revealed as part of his bid to be allowed to run in the Olympics. Chambers received a two-year ban as a result of a positive test for the designer steriod THG. 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 center of an ongoing investigation into steroids distribution in athletics and baseball that has already resulted in Marion Jones being sent to jail and may have a similar outcome in the case of Barry Bonds. Conte's letter, which has been leaked to the British media, was due to be 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. Chambers, 30, has re-established himself as Britain's best sprinter since launching a second comeback in January, gaining 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, which has decided not to take him on. Chambers is now contemplating legal action to overturn the British Olympics Association's policy of preventing athletes who have committed doping offenses from representing Britain in the Olympic Games. British shot-putter Carl Myerscough, who served a two-year ban for taking anabolic steroids, is also considering a legal challenge to the BOA's policy. Montgomery sentenced to 46 months Former 100-meter world record holder Tim Montgomery was sentenced to 46 months in prison Friday for his part in a multimillion-dollar fake-check scheme. The former Olympic champion, 33, hung his head as Judge Kenneth Karas imposed the sentence. Montgomery pleaded guilty last year to conspiracy in the bank fraud and money laundering plot. Prosecutors said he had a hand in depositing bogus checks worth $1.7 million. Montgomery retired in 2005 after he was banned from athletics for doping. He has a child with Marion Jones, who is now in prison for lying about the check scam and about her doping. “I've had everything I ever wanted in life. I've stood on the top of the mountain,” Montgomery told the court. But now, “the gold medal, all those people cheering, that was part of another world. ... In jail, my status is gone.” After the sentencing, Montgomery nodded and smiled at his parents, siblings and a girlfriend.
