Aggression comes from the individual, some people are just more aggressive (assholes) than others regardless of how much test you are taking. Me personally I don't get any aggression on test and/or any other prohormones. I believe each person is different and reacts differently.
I got up to 150mg by week 6 with min sides, small back pumps (taurine worked wonders) and some lethargy. But everyone is different, plus helladrol is very mild in comparison to others.
Background: 73 inches roughly 214lbs roughly 12% bodyfat per 3 site caliper, 32 years old, did some lifting in High School and some in the military, but off and on. I recently got back into lifting about one year ago, I eat pretty clean but still need to loose some more body fat "goal is 9-8%"...
