He could go to T-Mobile or CSC or another team that is bringing in blood profiling (although in truth they probably wouldnt want him because they wouldnt think he could replicate his previous results under their cleaner programme)
he could invite the spanish anti doping agency or the ADA of whichever country his team is based in to test him every month
he could arrange a televised press conference where he donates his DNA to spanish investigators and the UCI to clear up all those nasty rumours about a spanish gynacologist giving him assistance...
Hmm let's see, T-Mobile who had how many positives last season despite their no tolerance approach to doping? CSC whose DS revealed to the world last year (when his hand was forced) that he won the tour by cheating. CSC whose star rider 2 years ago was found to be involved in OP.
There are few if any (I can't think of any) vestiges of clean sportsmanship left in pro cycling.
