Amgen, sponsor of the Tour Of California and makers of EPO, which is rather like having a cigarette maker sponsor a cancer ward, are, like most drug companies rather up to there neck in bad practices. This jumped out at me from the link..and to my mind suggests good reason to believe the web of corruption surrounding EPO use go,s all the way to Pat and Hein who I believe knew all about Thom Weisel. Would not be surprised in the least that some kind of financial links exist.
"The company spent years trying to clone the gene. In late 1983, Amgen raised $40 million in an initial public offering underwritten by Smith Barney, Dean Witter and Montgomery Securities, founded by amateur cyclist Thom Weisel, who also financed the U.S. Postal Service Pro Cycling Team led by Armstrong."
