Not enough rope but they know he rustled the cattle.
From an article I linked to earlier:
"During the final 10 days of the 2012 Giro d’Italia, Kreuziger’s hematocrit rose from 43.2 to 48.1, finishing higher than his pre-Giro value of 45.1 — an anomaly, as most athletes see a decrease of hematocrit/hemoglobin “after physical effort of sufficient duration and intensity due to plasma volume expansion,” as the UCI attests; i.e., during the final 10 days of a grand tour.
A rise in hemoglobin and a drop in reticulocytes, or immature blood cells, can be indicative of blood transfusions, as the body shuts down creation of its own red blood cells. A higher than expected hematocrit and elevated reticulocyte percentage can also be indicative of the use of EPO to artificially stimulate production of red blood cells.
Kreuziger argues that he has never exceeded the limit values in his biological passport; part of his defense is that his elevated reticulocyte level is due to the prescription drug L-Thyroxine, which he takes for hypothyroidism. He has never tested positive for doping."
