My boyfriend is so much bigger as In hench than he ever used to be, I believe he takes a vitamin that increases his size?

Surely someone can't make themself look hench purely by eating and going to the gym, he doesn't over do it either in the gym, he mentioned the other day his friend said they've noticed he's got so much bigger like bulkier, I can't remember exactly what he said but he did say he takes some kind of tablet/vitamin, can that sort of vitamin affect your mood and your levels of anger etc because he is exceptionally angry when he's annoyed, he's violent

He says its because I keep pissing him off but I think its his vitamins etc thats causing excessive anger
