Tom Zirbel Tests Positive For DHEA

Tom Zirbel who has raced with the Bissell Pro Cycling team has had a “A” test come back positive for the banned substance DHEA. Zirbel was scheduled to race with Team Garmin-Transitions for the 2010 race season but was surprisingly missing from the roster when it was announced. It left wondering why, and it appears that now we know.

“I want to inform the cycling community that an ‘A’ sample of mine from a urine test conducted by USADA on Aug. 29, 2009 after the US Pro TT has tested positive for exogenous DHEA,” Zirbel said. “I have not yet received notification from USADA on the findings of the ‘B’ sample, but I expect to receive word any day now.”

“The US Pro TT was a major objective of mine this season, but I would never compromise my integrity for any bike race,” Zirbel stated. “At this point, I don’t know how this happened but regardless of the outcome of my ‘B’ sample I intend to find out with the help of a few accomplished scientists and doctors who have selflessly helped me since I first was notified of the ‘A’ findings.”

“With that in mind, I refuse to speculate about how this happened until we have solid scientific evidence. I hate that this situation could and will probably bring more negative attention to our sport, but I am confident that we will find answers and I will be cleared of any wrongdoing. In the meantime, I ask for your understanding and respect while I fight for my career and reputation during this personal matter.”

We at are saddend by the news of Zirbel positive test. We ahve interviewed him many times at the Tour of California and have found him to be a stand up guy. We find it hard to believe that he would have taken DHEA on purpose. but most important is that we hope that it is a mistake, or was accidentally ingested in some supplement he was taking.

The one thing we can be sure of is that if the “B” sample comes back positive it is nothing short of being bad for the Domestic Pro Cycling world.
