If you become aggressive on test, it is because you had aggression issues to begin with and the confidence boost you get with test is amplifying the problem.
Trenbolone is really the main roid sited when talking about roid rage. From my research, again it is individual dependent and talking with some people dependent on the amount of test taken with. Most people agree that test should be less than Tren during a cycle if you are rage prone or believe you are. For some reason the couple of guys I have spoken with that claim to have rage issues on Tren say this drastically helped calm them down.
