I did sust on my first cycle and it did hurt. But that was my first cycle and I was really inexperienced with giving myself injections. There is a certain spot on my quads and delts where I get almost no pain. Go look on this sites main page and it points those spots out for your quads and delts. All I can say is give it a try. I dont think you should pin 2cc's into any one site every 5 days.
