Matt DeCanio, a former US professional cyclist and confessed drug cheat who is now an anti-doping crusader, told tonight’s Insight program on SBS television that nearly all competitors on the Tour de France used performance enhancing substances.
DeCanio, 29, says he's willing to go before an inquiry and name cyclists, including any Australians, who are using drugs.
"I've seen an all-Australian cyclist… he had 27 vials of EPO," DeCanio said.
"I never seen him actually putting it into his arm but I saw the medicine in the refrigerator and then I saw them disappear and then he calls me on the phone `Hey, don't use any of my EPO'.
"… I've seen guys hiding injections in fanny packs, injecting it before the race, I've seen general managers, son-in-law doing glucose drips on Russians."
ASADA says that its new powers enable the organisation to investigate any allegation of possible doping.
"Cycling Australia is working closely with ASADA," the organisation said in a statement.
ASADA chairman Richard Ings also appears on the program entitled "The Cheating Game".
"We look forward to speaking with anyone who can help us with any investigation," the ASADA statement said.
DeCanio says he believes 99 per cent of elite cyclists use doping.
"At the highest level I would say 99 per cent of the guys are on it (drugs)," he said.
"If I were to have to bet my life on how many athletes in the Tour de France are on drugs, I would say one guy was clean."
Former Canadian sprinter Ben Johnson, who was disqualified from the 1988 Seoul Olympics after winning the 100m final, also appears on tonight's program and continues to deny he is a drug cheat.
Johnson admitted using steroids, but says he wasn't the only one using doping in that infamous 100m final.
Johnson says athletes do whatever it takes to win, including taking drugs.
But when asked by Insight host Jenny Brockie if he’d do it all again, he said he wouldn’t.
“I probably would go back to school and get a real education or maybe say a real trade…” he said.
