There is a french laboratory in France, considered as one of the best in the world for the drugtest results, Châtenay-Malabry who did say that they analyzed Armstrong old samplers and that the samplers were positive. Armstrong answered using the good old' jewish trick but changed holocaust for cancerous and said they didn't do their job correctly ONCE AGAIN (when the lab in question has never been responsible for major mistakes at all). To me, it says a lot but then again, not every but many top cyclists are and were in that position.
