Colby On Usman using EPO:
Ive heard first hand from people that he trained with. Some people that I may have wrestled college with that said the same thing. I know hes going to be doing it [EPO] theres ways to get around it the test. There not blood testing, just piss tests here and there. They are not gonna blood test him[Usman]. There gonna let him get away with it. But you know you gotta live with that, the rest of your life. You gotta live with that in your conscious, that you had to cheat your whole way thru your career.
I know I am an all natural American. I worked the hard way, blue collar, earned it, blood, sweat and tears. This is earned to the very core, to the very root. Naturally, I didnt cheat, I didnt cut corners. I took the long way to get here.
You know he[Usman] has to live with that and hes gonna have problems later in life you know. His organs, all that stuffs gonna shut down, hes taking years off his life. But thats the choice he has to live with, if thats what he wants to do thats what hes doing.
