I honestly dislike the actual act of pinning so much, I prefer Test E 400mg/mL, despite the more intense PIP. I can use less cc's, and therefore it's less time contorting myself , trying to relax, and holding still while trying to force the oil through a 25g needle. Pre-warming the oil, massaging, heating pads, and hot showers help a little to mitigate the PIP for me.
