Exogenous testosterone in Landis' A sample

The aftermath of 2006 Tour de France winner Floyd Landis' positive A probe for performance-enhancing hormone testosterone is far from over. Germany's public TV stations ARD and ZDF have since questioned their transmission of cycling races if the sports biggest problem is not solved, and the German cycling federation called for an anti-doping law in Germany on Saturday, one day prior to the ProTour one-day race Vattenfall Cyclassics in Hamburg.

To explain the positive doping test result after stage 17 of the Tour de France, which he won after an impressive solo ride in high mountains, Landis has argued that his relatively high level of testosterone was naturally produced by his own body. The analytical basis for the test being the ratio between testosterone and epitestosterone, normally averaging 1:1, a suspicion of doping is being issued if this ratio is higher than 4:1.

In Landis' case, German media have on Sunday rumoured the result to be 11:1. "In our medical files appear not only blood levels, but also our testosterone status," said professional cyclists' representative Jens Voigt before the race. "It shouldn't be hard to find out if Landis is telling the truth."

But, much more important than this seems to be that the tests performed on Landis' A sample included an Isotope Ratio Mass Spectrometry (IRMS) procedure, used to determine whether the testosterone is exogenous (contained within, but originating from outside the body) or endogenous (produced by the body itself). In the case of the American, L'Equipe reported that the analysis found testosterone of artificial origin.

Jose Maria Buxeda, Landis' attorney, contests the detection method via IRMS. "It's not reliable," he told French L'Equipe. "Most laboratories do not use it. In fact, the laboratory of Chatenay-Malabry must be the only one still using it." In the same edition of the paper, however, Christiane Ayotte, director of the anti-doping laboratory in Montreal, Canada, disagrees. "We use the method regularly," she said. "Moreover, more than half of the WADA-accredited labs perform it successfully. I'd even say that an IRMS which gives a synthetic result is very hard to contest. It's not a method that anyone can apply but the LNDD (Laboratoire de Chatenay-Malabry) has totally proven itself in this domain."

It has been pointed out that Landis' thyroid problems, the treatment of his inflamed hip with corticosteroids, as well as drinking alcohol on the night prior to stage 17, could be factors which could have affected his testosterone levels. "As soon as an athlete is controlled positive for testosterone, the same old stories come up," Ayotte continued. "The increase, even if natural, of the ratio testosterone/epitestosterone cannot, in any case, be explained by taking thyroid hormones or corticosteroids. Alcohol can in fact influence it, but only with women, and only for three or four hours."

I have trouble with a rumour being spread by German media and with anything coming from L'Equipe. I'm sticking with my rational side and waiting for more information, from more reliable sources, before I decide how I feel about this issue. As far as I'm concerned, this whole thing is still totally up in the air.

Exactly as the preceding posts indicated. The European press and the bicycling community at large tends to hate American cyclists. For that reason alone I await further results. Publishing this type of press is like publishing only FOX news reports.

I tend to go with the concept favored by our justice system (at least nominally): innocent until proven guilty--emphasis on the word "proven."

Oh please.... stop that, everyone. I've seen it in the other Floyd&Doping threads, and IMHO, it's offensive to non-USAnians.

If your patriotism has been scratched, that has nothing to do with Europeans vs. Americans.

Honestly... most people like Floyd, many people admire Lance. Do you think half the cyclists I saw on the last day of the tour were wearing Phonak gear out of Anti-Americanism?

I'd love to see him get off the hook but it's just so unlikely.

I agree with you there, I think a bit too much is made of this angle.

Unfortunately, you may be right. But we don't know that yet. I'm still waiting to see what not only Landis, but also Ulrich and Basso, come forth with to counter these accusations. There's a long way to go before any of this is proved either positively or negatively.

[maillotpois]

This is my question - why did Lance jump into this when he didn't say anything about Tyler??? He's not racing now and he was then is maybe one reason. They courted/are courting Floyd for Discovery. Another reason?

I know Tyler's "defense" now seems a bit silly in retrospect - but bear in mind that when it was all coming down - that was a test with no proven track record, no published false positive rate, etc. And Tyler looks as sweet and honest as The Floyd. (And sure I'm bitter 'cause I believed Tyler til about 2 - 3 weeks ago when they published that fax to Haven about he bill for all of Tylers drugs as part of Operacion Puerto....)

So - even if LA is not racing, whatever - he still has a lot to lose by coming out so strongly if it turns out The Floyd is not clean.

So what's up??!?!?

There's a good article about Floyd in the New York Times today.

Nice how the lab is going to close for vacation! How convenient. (They have agreed to run his test, though.) And nice how they claim to have not received his first request to test the B sample- and he has a five business day limit from the release of the A sample results to request that. Guilty or not- that lab seems very shady to me.

The article says that if the samples contain, what's the word, exogenous? testosterone, he can still try to prove that it came from say, sabotage or contaminated dietary supplements.

Here's an interesting thought from the article I linked to in the women/doping thread: (from 2004) I think the last sentence will apply to Floyd, too.

"Cycling even has its own Barry Bonds, in the person of American star Tyler Hamilton, whose Athens gold medal carries a giant question mark thanks to a positive test for an illegal blood transfusion—an old-fashioned doping technique that seems to have come back into vogue, ironically, because of more sophisticated tests for EPO, the endurance athlete's drug of choice. Hamilton is keeping his gold medal, thanks to a botched testing protocol, but he faces sanctions for a second positive test during the Tour of Spain. Like Bonds, Hamilton insists that he's innocent despite a steaming mound of evidence to the contrary. (Unlike Bonds, however, Hamilton is widely regarded as a nice guy, which is why many in cycling continue to believe him.)"

Insert cyclist of choice.... I wasn't gonna add "Mr. Landis", but in a few days....

[jpbayarea]

I have to add that it's impossible to imagine what happens to A body when
that body has been raced up 5 mountain stages in such glory and exhilaration as was Floyd Landis that day of his historic ride. I feel quite sure that something amazing happened that day. I hate to get all 'woo-woo' here but in such a moment as that race was for him, with nothing to lose and everything
to gain by focusing, hydrating, pushing to the very limit of what is possible for a human being....it's just possible that his SOUL was electrified by the experience and his entire body, organism, biochemistry and all functions of that body responded by going haywire.....

As someone else said, testosterone rises just in watching something such as this. How often have you experienced a strong desire to go out and RIP up the road after some exhiliarating moment of bike racing and ridden like never before, simply in the thrill of that excitement.

I refuse to judge him as a doper. I do not believe it, though I don't think we will ever know. I assume his B sample will also come back positive (of course) and he'll be found guilty, will appeal, will WIN that appeal, but his name is forever tainted despite it being unlikely that he did anything wrong. The system is foul, the lab is foul and the French do not want an American to win the Tour again. The people who cheered are different from those behind the scenes.

I know we are all very upset by all this and it's so unfortunate but I just choose to go with my gut and believe this man. He is just not dumb enough to do that when he knew he'd be tested and he knew the climate of the race and the sport. And still, I fear and believe no good will come of this, unfortunately, no matter what the truth is.

my thoughts exactly.

As more stories come in it looks like Floyd Landis is toast, but I have not
seen anyone raise this question:

They keep looking for for a source of elevated testestorne. But maybe there
is a cause of reduced epitestosterone?

Could it be possible that the dehydration and bonking the day before, coupled with the extreme effort on the day of the comeback is responsible for a depletion in the epitestosterone stores, thus causing the high ratio of
testestorne to epitestosterone?

Can anyone tell me why this is, or os not plausible?

[latelatebloomer]

My gut feeling is that something is weird here, and that it just makes no sense that Landis would be so stupid as to dope, KNOWING he'd be tested. He seems like the kind of person who'd rather ride clean and finish lower than take the podium dirty, and a lot of people who've known him seem to say the same. I haven't been following cycling for long, and you all know that I just loved seeing a Pennsylvanian wail the Alps - but this guy has a reputation for being smart, being honest, and riding like the devil on horseback.

True, isn't it, that it would only take one bad apple with access to contaminate samples, or even contaminate what a rider is eating or drinking...? With all the money involved, I just wonder. 'Cause something keeps bugging me.

I googled "testosterone/epitestosterone" and found an article that talks about drinking alcohol increasing testosterone levels. (I dismissed all articles from the general media and focused on peer review studies.) The way I figure it, he would have to drink 4.69 ounces of alcohol to increase the testosterone level. They are talking about pure alcohol, so 100 proof whiskey would be 9.38 ounces. Disclaimer - I did this from metric conversion charts on the web - if there is a scientist in the house, maybe she can check?

I couldn't find a direct link talking about how quickly injected testosterone clears the body, but most articles suggested that testosterone would need to be injected for at least 2 weeks to have any positive affect on performance. As was said previously (and forgotten quickly) just one shot of testosterone won't make him fly like he did in stage 17.

People need to quit getting their exercise by jumping to conclusions. This guy's career is on the line. We should know beyond a shadow of a doubt that he is guilty. Thus far, we don't.
