Talking about doping, third generation EPO to be precise...
I think EPO is prehistoric thing... '90's to early 2000's drug.
I believe there's new generation of genetic doping products. Very hard to detect. Impossible at the moment.
Anyone who follows pharmaceutical achievements of modern age, knows there are leukemia medicines based on genetic manipulation... And they're not new thing.
Leukemia, as we all know, attacks blood's (body's in general) immune system. White blood cells, to be precise (again), which are much more difficult to engineer than red, which are of interest for performance enhance. What I want to say is - if there's medicine to correct white blood cells' production, there must be drug for the reds too. And to clarify the claim, the medicine doesn't just increases the red blood cells count, it adjusts all parameters of blood which are of oxygen transport interest.
So, anyone who still uses EPO (for which we all know), in my opinion, doesn't look ahead of his time, to be harsh - is very dull.
P.S.
Designer steroids play roll too in modern doping... Especially for the sprinters.
