Wouldn't it be possible for McNamee to take steroids, and mix it with Roger's blood that he might have had from legitimate injections? (cortisone, B12 etc.) If that were the case, then there would probably also be traces of the B12, or cortisone, or whatever. If it's just blood and steroids, and Clemens says that the steroids were added later, then the question is, why was he being poked in the butt with an empty syringe?
