Honestly, I'm the kind of guy that just feels more concentrated, focused, that's it. Aggression is only in the gym. Surprisingly I am super cool on tren, or anything for that matter. Initially when I tried aas I had some slight aggression out of gym, but.. I am normally a very down to earth guy.
If anything it is the high dosing of test that leads me to be moody, as I've learned sticking to my doc's prescription of trt and running other aas makes me feel epic.
Doesn't change much for me other than just feeling confident/good some more. Some people may experience uncontrollable mood swings, agression out of gym, etc... but then those people I guess are more susceptible to those kind of issues to begin with.
I am on trt for life, so... I'll blast as much as I want without worrying of PCT, only overall health. So for me it's all good.
This pretty much sums it up for me as well. I do get irritable on certain compounds like Tren and Halo, but overall i feel more focused on cycle and have more energy in and out of the gym.
Everyone is different and i know guys who act stupid on gear, but like ahmed said above, the people who have problems to begin with are typically the ones who respond in a negative fashion. AAS seem to amplify your existing personality and moods. So if you are bipolar or an aggressive person, AAS will likely increase these issues in "most" people.
