I have been on Masteron for a few weeks now, and the aggression is a mixed bag. I love it when I am lifting, but I work in an office around people all day, and everything has been getting on my nerves lately. I haven't really 'snapped' at anyone, but I can definitely tell that I am more irritable.
I have read the aggression on Tren is pretty bad too, but which do you think is worse? Masteron or Tren?
