I was doing .4cc of prop (166mg/ml), .6cc of tren (100mg/ml), .5cc of winny (50mg/ml) and 1cc of b12 ed, and had no pain.
Now I'm doing 1cc of prop and 1.5cc of tren eod, and it hurts like a mother, at least in my quads. Biceps hurt, but not as bad (did 1/2 that in each, plus .5cc of b12 per). I'm hoping chest is painless tomorrow.
