I think you're a bit naive, yes but all credit to you for that instead of being cynical. As for hard proof, there is none for today, but it was done in the past (See the GDR or Armstrong).
To say they would be offering PED to win Algarve is kind of a understatement, it's about the biggest races of the season, no?
I thought the Armstrong example showed my point of view. Clean the first few years at least and then coming to the realization that one can't compete for the big wins without PED.
Sure, a bit silly example by me on the Algarve - I thought I made myself clear. What I mean is that Seixas is competitive with the best GC guys, barring the two astronauts, and that this indicates to me that one does not have to endure the years (1000 days according to Tyler Hamilton) of getting crushed before joining the club.
My thinking is this: Either there is no club, or the club is wide open even for teenagers on Groupama-FDJ and other teams who are members of the MPCC. I think if the latter is true, we would have known more about it. Very hard to keep those secrets if they run wild in a teenage milieu.
I think most races are won by basically clean riders - but I don't know why everyone is so freaking good. I'd like to understand more about that.
