At the Winter Olympics in 1993/94 in Lillehammer, Conconi gave a talk to members of the International Olympic Committee and informed them about his work on an EPO test. He described how he had carried out controlled experiments with 23 amateur triathletes and other athletes with EPO treatments but that he had not come up with a test to detect EPO use. The details of Conconi's 23 amateur athletes were later discovered by police after a raid at the University of Ferrara and that there were no 23 amateurs but elite professionals, six of which were from the Carrera Jeans-Tassoni cycling team.[12]
Conconi had listed subjects' names, gender, sport, date of analysis as well as whether or not they were treated with EPO. Despite funding by CONI and the IOC to come up with an EPO detection test, Conconi was using the money to buy the drug and then administered it to athletes who were also paying Conconi.[12] Conconi is said to have made a technique to balance EPO, Blood Thinner and Human Growth Hormone in a mixture that Athletes could take safely and pass doping tests without testing positive. With this ability to safely take EPO, Donati estimated that 60 to 70% of the peloton used EPO in the mid 1990s.[13]
The team doctor of the Carrera cycling team, Dr. Giovanni Grazzi, worked with Professor Conconi at the University in 1993[9] while the following year, 1994, another professional cycling team, Gewiss-Ballan, were connected to Conconi via Doctors Michele Ferrari and Ilario Casoni. In addition a number of well known cycling stars were clients of the Institute.[2] The Gewiss team attracted a lot of negative attention when after taking the whole podium in the La Flèche Wallonne Classic in 1994, Ferrari in an interview with the French Sports Daily L'Equipe, compared using EPO to drinking orange juice.[14] Bjarne Riis the 1996 Tour de France winner was a rider of the Gewiss team and was treated with EPO in 1994 and 1995 in Conconi's Institute in Ferrara. During the 1996 season Riis was coached with one of Conconi's assistants Cecchini and would win the Tour de France.[15]
It would be reported in the Rome based newspaper, La Republica, in January 2000 that Conconi was involved with administering EPO to riders on the Carrera.[16] In March 2000 the Italian Judge Franca Oliva published a report detailing the conclusions of an investigation into a number of sports doctors including Professor Conconi.[17] This official judicial investigation concluded that the riders of the Carrera team were administered EPO in 1993.[12] The riders included Stephen Roche, Claudio Chiappucci,[18] Guido Bontempi, Rolf Sørensen, Mario Chiesa, Massimo Ghirotto and Fabio Roscioli.[9]
Files seized as part of the judicial investigation allegedly detail a number of aliases for former Tour de France, Giro d'Italia winner and World Champion Stephen Roche including Rocchi, Rossi, Rocca, Roncati, Righi and Rossini.[19]
In 1997, Claudio Chiappucci told prosecutor Vincenzo Scolastico that he had been using EPO since 1993, but later he recalled that statement.[20] Marco Pantani was part of the Carrera Jeans-Tassoni team and his hematocrit level displayed rises and falls which looked very suspicious. On October 18, 1995 Pantani was taken to hospital after an accident in the Milano–Torino race where a hematocrit percentage of 60.1% whereas in the previous June it had been 45%.[21][22] At this time there was no limit to the hematocrit level but the large fluctuation was suspicious.
