Ahh the modern age, where no one feels like enough of a man.
Steroids are pretty awful. If he's been breaking shit and having angry tangents thus far, it'll go up with that. He'll also be more likely to return to his drugs of choice to try to self-medicate the emotional imbalances.
The health detriments are also pretty shitty. It can fuck with sexual performance, social capabilities, self-control, a lot of areas. I knew a dude who abused the stuff and smoked weed near-constantly to try to keep himself under control, but... at his heart he was a nervous, fearful person, and it just turned all of that into rage.
