[Montreal's bullpen catcher Luis Perez] told Hallinan that when teams were in San Diego, players often crossed the border into Mexico to obtain illegal substances.
Ouch... Also, here are all the mentions of the word "buttocks":
Laker followed the same regimen after each purchase of performance enhancing substances from Radomski. He injected himself in the buttocks once a week for eight to ten weeks, took some time off, and then repeated the cycle. During home stands, Laker injected himself at his residence. On the road, Laker injected himself in his hotel room but brought the used syringes home with him to discard.
Later that summer, Clemens asked McNamee to inject him with Winstrol, which Clemens supplied. McNamee knew the substance was Winstrol because the vials Clemens gave him were so labeled. McNamee injected Clemens approximately four times in the buttocks over a several-week period with needles that Clemens provided. Each incident took place in Clemens's apartment at the SkyDome. McNamee never asked Clemens where he obtained the steroids.
According to McNamee, 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 that McNamee had obtained from Radomski.
The five players and Seyler all injected themselves with the steroids at the apartment. Seyler witnessed Herges and Williams inject themselves in the buttocks with syringes containing Deca-Durabolin. Seyler also observed Lo Duca and Judd inject themselves with either Deca-Durabolin or Winstrol, although Seyler could not remember where they injected themselves or which of the two substances they used. Seyler further observed Stone inject himself in the thigh with Deca-Durabolin. Seyler injected himself in the thigh with Winstrol. Seyler said he was inexperienced in the use of anabolic steroids and needed Herges to explain to him how to perform the injections.
Karchner said that during spring training in 1999, he observed two of his Chicago Cubs teammates inject themselves with steroids in an apartment that Karchner was sharing with them. Karchner declined to identify the players. He said that one of the players brought the steroids to the apartment but was afraid of needles and therefore asked the second player to administer the shot. The second player injected the first player with steroids in the buttocks and then injected himself.
