I wouldn't go so far to say roid rage is a myth, 600mg is not an outrageous amount, the hardcore bodybuilders and some athletes will do much more then that. It's certainly possible that 3x that dose induces unnatural rage.

It’s not a myth, it absolutely does increase your anger and your drive. It also massively increases libido.

That’s one of the reason that transgender treatment is so insidious. Give a depressed teen girl testosterone and they will always feel incredible. Regardless of whether it’s actually a medically necessary treatment, it’s a treatment that makes you feel good. Psych meds can’t compete.
