Preparing skin for injection.
Clean the selected injection site with an alcohol pad rubbing in a back and forth motion.
Remove the cap from the syringe (being careful not to touch the needle).
Hold the syringe in one hand like a dart or pencil
Grab the skin around the injection site with your index finger and thumb.
Quickly thrust the needle into the skin at a 90 degree angle. Do not insert it slowly or go all jack the ripper on yourself.
After the needle is inserted release the skin that you are grasping.
Press down the plunger slowly and steadily.
As you pull out the needle apply a piece of sterile gauze.
Pro tip: apply a spongebob square pants bandaid because that **** is so cash.
Replace cover of the needle and dispose of responsibly.
