About Di Lucas positive, I have an outragous theory:
Di Luca was being targeted for testing due to suspicious but not conclusive bio passport tests.
Di Luca was using the standard epo micro dosing thing that is thought to be undetectable.
His samples were taken to the cologne lab, which i theorize is usually the first to get improved procedures and equipment.
They flag him, and now he is out.
Meaning micro dosing with epo might not be as safe as previously assumed.
Being a long time doper with financial recourses, I find it difficult to assume that he did not use the most advanced methods. Hence I'm of the opinion that microdosing if you are flagged as worth targeting by the BP, is no longer a safe option.
It could of course be that someone in the UCI is still able to protect certain riders, and Di Luca was not deemed worthy of protection.
It could also be that this protection does not make one immune to targeted testing. And if that testing finds a positive, protection is no longer possible.
Perhaps this protection is limited to cases were the BP is the only evidence.
Or perhaps there is no longer any protection available, and that the amount of dopers caught is at this time more a question of funding available for targeted testing?
