Lance Armstrong... greatest doper there was or ever will be

I just find it interesting regarding what's considered acceptable.
For example, EPO and blood transfusions are banned but training at altitude or using an altitude chamber to sleep in in order to increase your blood count aren't yet they have the same effect.

They don't have the same effect though.

Everyone can train at altitude. Not everyone is willing to risk their health to the same extent to win and nor should they be required to.
