That's because he could go to the Dominican Republic for his supply. They don't have smoking guns in the DR (except for Manny Alexander). Sammy has proven that he is not above cheating, e.g. corking his bat. Given that, I am fairly confident that he would have no problem taking steroids. But that just answers part of the questions. Supply is one thing, but where would he have injected it? Sosa wouldn't have taken steriods exclusively in the DR in the offseason, would he? I don't think the drugs work like that. Where would he inject it? In his butt, I don't know, but he probably injected while in the u.s. He gets his supply in the offseason in the DR and takes them during the season. Pretty simple.
