alright so this is my second go at pinning hcg. i mixed 5000ui with 10ml water, and am taking 2X250ui on cycle. firts try: two inches right of belly button, pinning was fine, no blood vessels hit, but as soon as i slowly pushed the plunger it hurt like hell. i only got like 1/10 the dose in. Next day: I try again, with upper outer buttocks. I got the same pain, but managed to get a little more in before calling it quits. I'm hitting with u100 insulin needles at 45 deg. while picnhing up skin...Is it supposed to hurt like that?
