What? What? In the butt

From the AP's report about the Mitchell steroids findings:
Clemens was singled out in nearly nine pages, with much of the information on the seven-time Cy Young Award winner coming from former New York Yankees major league strength and conditioning coach Brian McNamee.
More than a dozen Yankees, past and present, were among the 75-plus players identified.
"According to McNamee, from the time that McNamee injected Clemens with Winstrol through the end of the 1998 season, Clemens' performance showed remarkable improvement," the report said. "During this period of improved performance, Clemens told McNamee that the steroids 'had a pretty good effect' on him."
McNamee also told investigators that "during the middle of the 2000 season, Clemens made it clear that he was ready to use steroids again. During the latter part of the regular season, McNamee injected Clemens in the buttocks four to six times with testosterone from a bottle labeled either Sustanon 250 or Deca-Durabolin."
