Some interesting things implied by this schedule:
1) withdrew blood in the second week of January, and again in the last week of Feb., but did not transfuse until March 7. That is about 8 weeks after the first withdrawal. You can’t store blood refrigerated that long. So that first withdrawal, at least, would have to be frozen. In fact, I think all the blood withdrawn by this rider was frozen, because at no time does he couple a withdrawal with a transfusion, as one normally does when one is storing blood refrigerated; I discuss this further below. And also because in late June and July he is transfusing blood up to more than six weeks after the last withdrawal, and much longer after earlier withdrawals, which would have been needed to supply all this blood.
2) Note the heavy use of EPO preceding withdrawals that are not closely associated in time with reinfusion. The idea is to build up the HT so that blood withdrawn is rich in red cells, and to minimize the weakness following withdrawal.
3) The first transfusion is Mar 7. Since that is not coupled with a withdrawal, and since it is so long after the first withdrawal, I assume the transfusion was to increase HT for a race. It would probably be for a week-long stage race (is there one at that time?), as he did not withdraw until nine days later. If it had been for a one-day race, he mostly likely would have withdrawn soon after the race. See the next point for more on this.
However, the transfusion for the race was only ten days after the previous withdrawal. That is not enough time to recover fully from the withdrawal. I assume the rider had no choice, as he needed more blood in storage. Notice he did not use EPO to accelerate recovery after withdrawal, as withdrawal itself stimulates reticulocytes, and you don’t want to do anything more to alter your parameters.
4) Has a second transfusion in April. This again was most likely for a race, since it was not immediately coupled with a withdrawal. A withdrawal did occur two days later, suggesting the transfusion was for a one day race. The transfusion-withdrawal coupling I don’t think was just a way of recycling stored blood so that did not become dated, because normally you would withdraw first—so that the withdrawal does not contain any previously stored blood—and you would carry out both procedures at the same time, so there is no period when your blood has abnormal parameters.
5) Same with the transfusion at the end of April, which is followed a week later by a withdrawal. Suggests that this transfusion, too, was for a stage race.
6) Following the withdrawal in the beginning of May, he does take EPO, which is risky. But he only withdrew a half portion of blood, and he needs the EPO, as he wants to withdraw again in about a month. At that point, he has enough blood for the rest of the season, which almost certainly involves the TDF (three transfusions, one of them maybe before the race begins, the other two during).
Information like this would be very useful if one were betting on the races. E.g., I would bet the rider did not do that well in that stage race in early March, because he didn’t have enough recovery time from the withdrawal at the end of Feb. This also provides more insight into why riders who do very well in the TDF often don't do much during preceding races. Because of the constraints of blood withdrawals, they often can't enter these races at maximum fitness, not if their first priority is to have enough blood in storage for several transfusions during the TDF.
