P ost. I njection. P ain. Doesn't really happen until you get to prop, or even sust, a little. Or, really high concentrations of mg/ml. There are some tips & tricks, floating around here somewhere. Ie. Pinning 1st thing in the morning, doing cardio & then taking a shower, works for me. Warming your gear w/a hair dryer b4 drawing it up from vial, following proper protocol, using good form & technique, using a smaller gauge needle, yada yada yada... Feel free to pm me if you can't track them down. It's really nothing to worry about though. It's easily managed : )
