For pip, it really wasn’t bad once the individual injection site got used to it and I was pinning 1.5ml of 200mg 3x a week. It was roughly same soreness level as the very first test injection in virgin muscle. And once a site was used to it, I really didn’t notice a difference when I switched labs, which I did during two runs when I decided to continue a few weeks longer and could see I would run out before completing.
