ATHLETICS: Dwain Chambers took a cocktail of 300 drugs in one year during which time he passed 10 tests, the disgraced sprinter has revealed.
Chambers tested positive in October 2003 for the banned steroid THG, which he began taking at the start of 2002 after linking up with Victor Conte, the self-made sports nutritionist and founder of BALCO.
In his autobiography, Race Against Me, Chambers revealed: "Barely four months into my 'programme' to become the fastest man in the world and I was on drugs nearly every day. At this point I was practically a walking junkie. I was on the lot and the sophisticated modern-day tests detected nothing.
"I was routinely tested for performance-enhancing drugs by an independent tester. Not once did I test positive. By the time I had passed 10 tests, I had won a European gold but my times were hardly improving."
Chambers revealed that drug-induced cramps forced him to pull up in the Commonwealth Games 100m in Manchester in 2002.
"By the time I walked back to the dressing room, the cramps had almost gone," he said. "Physically, I was fine; mentally I was in turmoil. I watched the replays on TV later and wondered for the first time what sort of damage I was doing to myself.
"In October I administered substances 21 times. I wasn't just on THG, EPO and HGH, but testosterone to help with sleep and reduce cholesterol. I was also injecting insulin, three units into the lower part of my stomach after a heavy weightlifting session.
"On Christmas Day, as I sat in the bathroom with 'The Clear' (THG), I realised I had been taking drugs - more than 300 different concoctions - for 12 months. A year on the programme cost US$30,000 (€23,800).
Meanwhile former sprinter John Regis, Chambers' former agent, has threatened to sue Chambers over allegations in the book that he was aware of Chambers' drug-taking activities.
Regis told the Daily Telegraph: "I can 100 per cent categorically deny any knowledge that Mr Chambers had decided to take performance-enhancing drugs."
