Wow, this is crazy shit! So, just for fun I looked up 'buy epo' on Google. Now, I realize there are large number on this forum who know way more than I do and that this has very likely already been covered by others, but nevertheless, here is my point ...
It looks like you could likely buy enough EPO to "fuel" your performance very well for a season, and it would not cost you more than tricked out carbon wheels and Optygen for a year (Optygen for a year is what, about $1000?). Before I get raked over the coals, I am not saying that EPO supplants training or genetics. But, I think I could "buy" myself much better results via EPO than spending money on Optygen and those new carbon wheels I just bought!
The reason why I even bring this up? You don't have to be pro-tour to have access to some seriously powerful cheating tools. And you can do very well and get lots of fame and $$ on your way, and perhaps get noticed by a big team, which takes you to the next step, etc. This stuff makes me glad I am an old fart who now rides/races just to blow off steam and stay in shape.
