Staci's big brother Matt is just about the greatest brother a girl could ever have. He's the star our their high school football team, and he's probably going to get a scholarship to a great college. Matt used to be pretty skinny, but he's built himself up so that he's a real hunk-muscles on top of muscles! Of course, all the girls in the school are absolutely crazy about him. But now, kids are whispering about him using steroids to get so big and strong. Staci just can't believe Matt would do something that dangerous. But when she asks him if the rumors are true, he gets really weird about it. He just flexes his muscles and says he's as strong as a horse. And besides, he says steroids can't really hurt him. Staci's really scared. What if he's wrong...DEAD WRONG!
