i did my first injection today, i used a 1inch 25g pin to inject in my quad, i poked it in, just felt a pinch than i pushed the syringe and kept pushing for a while and i started to wonder why it wasnt going in anymore i looked at it and the liquids were all gone, it went in sorta fast and my hands were a little shaky, so i was wondering what could i apply to the injection spot to prevent soreness?
