But if your going with the 22g missile then go slow, pierce the skin the push the needle in. Once your in an inch into the appropriate muscle group (quads, pecs, delts, lats, traps {glutes 1.5"}) then aspirate by pulling back on the plunger of the syringe and looking for blood. If you start drawing blood then pull out and try again. if no blood then inject slowly.

Id suggest warming up the vials too, especially if its cold. For me it lessened the pain vs cold oil the day after.
When you aspirate is it to see if you hit a vein?? How bad would it be if you did do this or didnt check...just wondering....
