knower of things- your 'experts in wada' are very VERY wrong. There is an ever growing body of research indicating massive flaws with the test for EPO including studies that indicate hard 'strenuous' exercise can lead to a false positive
"EPO is a protein," Beke said. "Everybody has it in their body. The main problem is when I do high physical activity, especially anaerobic, I produce a lot of proteins. The problem is that with everybody else there is a filter in the kidneys that stops your proteins from ending up in your urine. When I do anaerobic exercise the filter doesn't work properly and all these proteins end up in my urine"

I' am thinking he was tested post Chicago and if so he pushed his body very hard that day....
