Snap the the top off, open a syringe 23/25 Ga. draw up the gear, switch pins, and ENJOY....
I'd say first time go into your glute opposite of which hand you are, (If your right handed stick your left glute) you will have better control, Clean the pin area with alcohol wipes in a circular motion, touch the pin to the skin and push in steady, try not to move it side to side, just a nice smooth movement in, Once its in pull back on the plunger to asperate, if there is no blood push the plunger in slowly and steady.... Thats it now gently pull it out wipe it with a alcohol wipe and put on a superman bandaid and your done...
