The last couple years I have been experimenting with EPO in training and racing. I am a top MTB Expert and Road Cat 2 racer. I am ready for Cat 1 and MTB pro. My question is....Are there any long term effects for taking EPO? I have not experienced any drawbacks since being on this stuff and I am making huge gains in my performance. I have never been tested either. What's the probability that I wil get tested in the Cat 1 /MTB pro ranks? I have heard from other pro's that there is virtually no chance of getting caught if you do it smartly. So far I think I am using it wisely. Anyone have personbal negative experiences with EPO? Thanks
