so i'm wondering why positives never came back for piepoli and cobo after their remarkable win on hautacam? piepoli supposedly confessed to using epo. so what's the deal, was it pushed under the rug or did the tests not really work and if so how many others got away with using epo this tour? did aso strip piepoli of his stage victory or does it still stand? thanks for any info because i can't seem to find any.
