Lance Armstrong said on Wednesday he doubted if his results from independent anti-doping tests would be given a fair hearing.
However, the American said he would push ahead and publish data through independent anti-doping expert Don Catlin that proves he is racing clean.
Armstrong is making his return to cycling at the Tour Down Under this week after a three-and-a-half year hiatus.
Before the event, the seven-time Tour de France champion declared that results from tests carried out by Catlin would soon be published.
In a bid to beat the doubters, some top cycling teams make the results of strict internal anti-doping programmes available to the media.
However, as yet, no results from Armstrong have been made public.
Armstrong said on Wednesday he would now depend fully on Catlin to decide what information would be made available.
”I would rely a lot on what Don Catlin wants to publish, but we will definitely [be] publishing data and information,” Armstrong added.
He said, however, he had fears some of the data could be misunderstood because of its complexity.
Armstrong said he fears the misreading of his haematocrit (red blood cell count) level — a biological parameter than can indicate, but not necessarily prove, blood doping — could be misinterpreted.
Haematocrit levels are generally in a bracket of 40 to 45, although the legal haematocrit level in cycling is 50.
The use of banned blood products that enhance performance usually raises the haematocrit level towards that permitted threshold, thus prompting suspicion of cheating. However, haematocrit levels are also known to fluctuate naturally.
Armstrong said: ”Say, for example, hypothetically, it [haematocrit] is 43, 42, 41 and you then go to altitude for a month and it goes to 46.
”Not everyone in this room is going to say that that means I must have cheated. But a few of you would say it was suspicious.”
He added: ”I sat down with one magazine journalist and this guy says, ‘our physiologist says it’s absolutely impossible for your haematocrit to rise during the season.
”[But] if you go to altitude training for four weeks or six weeks, you get sick, you get dehydrated. And he’s telling me it can’t go up? That’s ridiculous.
”When you publish [information like] that … then you open yourself up to all this other criticism.”
Armstrong, who revealed he could go on for a full two years, said he has been tested a total of 13 times since August — tests carried out by his Astana team and the various anti-doping bodies.
After initially saying he would only ride for one year, Armstrong said he could consider going on for two years — but no further.
”This comeback is at least a year. It’s not three or four, I don’t think. It could be two years.”
”There’s other things too that need to fall into place, but with my condition and how this all feels and how the campaign unfolds, I can tell you this: If I am racing, I’ll be back here in 2010.” — Sapa-AFP
