Not disagreeing with your absolute logic, but I think you're out on a limb with that view.

1. read the friggin OP
2. read your post.
peterst6906 said:Wrong on both counts. Read HJ's response and whether or not EPO use is associated with blood transfusions, at a point either directly in the future or after re-infusion, a performance enhancement is expected and directly linked to the EPO use.
It's performance enhancing and a no amount of ridiculous pulling apart of the series of steps will change that.
Dear Wiggo said:My statement is being made in the context of a thread where a Doctor says your EPO increases when you donate blood.
peterst6906 said:No, you said this:
"EPO itself - I believe - is not performance enhancing at all."
Not performance enhancing at all. Rubbish, but keep believing what you like, you still cannot separate the end result from the first step.
If you were to draw up a list of banned substances for WADA, would you include EPO as an erythropoiesis-stimulating agent on that list?
Simple question.
Dear Wiggo said:Of course.
Simple question: from the time you take EPO until the time you see a performance enhancement, how long is the delay?
ie if you took it 1 hour before a race, would you gain any performance enhancement?
2 hours?
4 hours?
How long?
peterst6906 said:I wouldn't take EPO as a pharmaceutical substance.
peterst6906 said:However, in general terms that is not an answer that has a definite answer as there are many factors that affect the time between taking EPO and having an increased oxygen carrying capacity in the blood.
The time is however, longer than the 2 timeframes listed.
peterst6906 said:So if I understand your context further, you are suggesting it is OK to take EPO and race, as long and you don't race at some point in the future when you would be expected to gain a benefit?
peterst6906 said:Incidentally, why would you include EPO on a banned list?

Wrong. A reticulocyte is an immature red blood cell. Hemoglobin is a protein which is a component of all red blood cells including reticulocytes. Reticulocytes therefore do not mature into hemoglobin, they mature into erythrocytes.Dear Wiggo said:EPO triggers reticulocyte production in your bone marrow. An increase in EPO (via injection) leads to an increase in reticulocyte production. Reticulocytes themselves are not performance enhancing. After a while, reticulocytes mature into hemaglobin. An increase in hemaglobin is performance enhancing.

I think you dropped your chain very early in the stage. Come again, master of logic.peterst6906 said:That's a significiant deconstruction of the process.
Once you begin a chain of events by injecting rhEPO into the body, can that chain of events, which ultimately leads to performance enhancement, be broken or is there an expectation that injecting rhEPO will lead to a performance enhancement?
The whole purpose of injecting rhEPO is to produce an effect on the body and that certainly isn't expected to be a reduction or even a stasis in performance.
The whole process is a single event, involving a series of deterministic steps. The end result can't be separated from the beginning step.
So the flip side (and more common view) is that EPO is performance enhancing.
Not disagreeing with your absolute logic, but I think you're out on a limb with that view.

So of the three blood cell types: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets (thrombocytes) - only the red blood cells contain Hgb yeah? Red due to the iron content which is what Hgb contains yeah?
So when you measure the Hgb in blood - it only measures the matured retics (RBCs or erythrocytes) yeah?
sashimono said:It would be funny if bloodletting turned out not to be quackery.
[Hb] is expressed as g/L or g/dL of whole blood, which means you are including the hgb contained within retics as well as erythrocytes in that value. But of course since retics are only 1-1.5% of the total red cell volume, the total amount of hgb located within retics is going to be very small relative to erythrocytes.Dear Wiggo said:Thanks.

As you have already explained to others, taking blood out in order to stimulate EPO production is totally counterproductive to performance. VO2max will go down and it will take a good 2 weeks or so for the red cell volume to normalize (depending on how much blood was taken out).
