Think what you want to think - I don't really care.
The bottom line is that distance runners continue to use & get caught for EPO. Nothing has changed in over 30 yrs when the blood-boosting drug made it's way to athletics in the early 1990's.
And not only distance runners but some sprinters have been known to use it as well. And not only athletics, but cycling, triathlon, cross-country skiing, swimming & even rowing. No endurance sport is immune to it - where there's professional endurance athletes competing you'll find EPO (imagine that).
Despite much improve testing for EPO & the implementation of the ABP - athletes continue to use it. And despite the penalty for a conviction going from 2 yrs in the 2000's to 4 yrs for a first offense - athletes continue to use it.
You'd think if EPO wasn't efficacious & didn't provide any benefit to elite endurance athletes - they would have realized that over the last 30 yrs & EPO would have become obsolete & buried into the "non-effective" drug grave.
But instead athletes continue to use it & as long as professional endurance athletes exist, they'll continue to use it indefinitely.
And rekrunner --- even race horses use it! Lol.
