EPO was always detectable. The trouble was detecting synthetic EPO. In fact, the maker of synthetic EPO (Amgen) was the title sponsor of the Tour of California!

After they developed that test stage speeds dropped dramatically. Now speeds are back up to where they were right before the EPO test was developed. You really think that’s natural?

Cycling has a doping scandal once every decade or two. Why would another one kill the sport this time when it never did before?
