I think the folks who say the rage is all in your head must not have a pre-disposition to rage. I have always been a high strung, easily frustrated person. Once the test is increased, Im no meanor or more aggressive but I find it easier to get frustrated. But again, I tried various gear and finally found what is easier for me to deal with and whats not. I dont seek huge immediate gains. I have always tried to be safe first and pay attention to what my body is telling me about a particular cycle and particular gear. Listen to your body!!
