anger management problems dont always relate to aas usage. just because he gets angry enough to threaten does not mean he is using gear. however usually steroid use almost always comes with gains in size, not just strength. now, this is a generalization, not the exact rule, but it is a really safe bet that he should be adding size if he were on steroids. but even still, using steroind dont automatically turn you into a good fighter, so i agree that you should just kick his ass.
