I understand that McGwire is listed in the "real list" posted several messages back, but he's not mentioned in any reports at either si.com or espn.com (including reports meant to summarize the list of report targets), and in the actual report he appears to be mentioned in connection only with andro and the Jose Canseco saga. I don't see any specific allegation against him along the lines of, for example, Kent Mercker:
Radomski stated that he sold one kit of human growth hormone to Mercker in October 2002. Mercker had recently undergone surgery and, according to Radomski, was seeking human growth hormone because he believed it might accelerate his recovery. Radomski sent the growth hormone by overnight mail; Mercker paid by check.
