How about them being "just the finishing crutch' then..? 
Ronnie could sign off on that

. Poor fucker.
I respectfully disagree with Mr. The Scott inasmuch as genetics played such an insignificant role in Mike's development. Of course he took steroids...he was never why about admitting as much. Believe it or not, however, he was clean far longer than many suspect (again, so he told me). He never really said when he started, but from our conversations,I got the distinct impression it was around the time he turned 18.
After that? I know he loved Deca. I think he liked Dbol for off-season bulking, but he didn't talk doses.
