I think Donaire has made a career mistake with Conte. For a smart man, I think Conte is kinda stupid.

What Conte has done is use a "smart ass way" for the body to produce EPO it wouldn't otherwise produce naturally. It's semantics. Those that are against the use of unnatural elements in the games will go after him to outlaw the tents, masks and the like.

Personally, I believe EPO's real power is the placebo effect. It doesn't give a fighter more skills, power, speed or punch resistance and the only time anyone can put up a tangible argument in a contests outcome, is if stamina is involved.

So the thing is when they take the blood sample, the profile will show unnatural levels of EPO in the blood which is a the red flag for further testing to look for synthetic drugs. however since the method of over producing the EPO was through tricking the boding, there is no synthetic EPO to find. Thus there is no PED's in Donaire's system.
