Ullrich's alleged doping plan
The Suddeutsche Zeitung has published what it claims was Jan Ullrich's doping plan for the first week of the Tour de France 2005, based on information from Operacion Puerto. For the first seven days of the Tour, Dr. Fuentes prepared him a series of hormones, insulin, cortisone, testosterone and blood transfusions, the newspaper alleged. It claimed that there was a "Roadbook" for the Tour 2005, which investigators link to Ullrich.
On the first day, according to the SZ, the hormone HZ was listed, the second day insulin I-3, the hormone TGN and cortisone, the third day TGN and PCH (a testosterone shot), on the fourth day HMG, a hormone mixture, a "rest day" on the fifth day, the sixth day insulin I-3, and on the last day, the re-infusion of his own blood, as well as insulin I-3 and vitamin E.
The newspaper also notes that it is not clear who might have helped Ullrich with possible transfusions, and notes that experts say that Pevenage or Ullrich himself might have managed it. There is no indication that the medical or support personnel of the team were involved, according to the SZ.
