If ur talking about personal experiences then steroid use def effect your emotions and personality to a certain extent. When u start messing with your hormones ur going to get changed in other places other then your muscles which most people don?t understand. Steroids usually give you more aggression and confidence. I also am in a much better mood when on test but I am also low in test for my age. Tren is a total mind fuck and I will never try again not worth the gain in my opinion.
