Cardio is pointless, it doesn't build muscles very much. Lift weights instead.
I don't think it 'kills gains', but it burns calories which could be used for better things like gaining, lifting and homeostasis. Food costs money, you know. Maybe if you want to eat crap like cookies and cakes then you should run a bit to burn that trash off but otherwise I don't see the point unless you're cutting.

also dropping the word "roid" is a strawman argument
