Milos said that Mustafa Mohammad would show up two weeks before a contest at 15% body fat, then somehow make it to the contest, stage ready, at under 5% body fat.
I think that was about right. It may have been a month out at 15-20% body fat, but either way - whatever the cut was, I remember thinking "How can a person cut body fat that quickly?" One way or another, Mustafa did it.
