Testing for EPO did not exist at first. The reason EPO was used was because it was not initially testable.

The whole point of cheating is not getting caught - which means keeping one step ahead of the tests in the technology you use.

It's simple logic: if the testmakers were creative enough to predict how the testfakers would find a way around the test, and they would anticipate that workaround . . . ad inifinitum.

The real reason was nothing else increased your hematocrit level like EPO.
