When I had low T I was an angry prick, everything pissed me off.
When I'm on cycle my mood is at it's best regardless of compound, tren is an exception in that it enhances my mood, so it's harder to piss me off but if you flip that switch it's boosted.
When my estrogen gets out of control I turn into a bitchy cunt.
I believe roid rage came out of the old days when guys would crash their hormone levels causing unstable moods - one of the things some low T guys have to deal with, that is usually corrected with TRT (I fit that example).
So I think "roid rage" is a myth, but i do think unstable hormone levels can cause mood issues.
