I am not saying the American women are for sure not doping...in my mind there is a 60% chance some of them are as well as those from other countries. However, I think it is far more likely (95% in my mind) that Ayana, the Dibabas, the steepler, and a few others are. I just think there is a much bigger benefit to be had when you can do a full blown doping program without fear of OOC testing vs only being able to microdose in a more rigorous OOC environment.
