4 - Wipe this area with an alcohol wipe.

6 - Flick the syringe with the AAS compound in to remove any air bubbles and push the plunger so that 1 or 2 drops come out to lubricate the needle.
7 - Push the needle into the alcohol swapped site.
8 - Aspirate (enough to see an air bubble / if you see blood, withdraw the needle, change the needle and select another pinning location).
9 - Once you have seen an air bubble from aspirating, you're ready.
10 - Push slowly down on the plunger to inject the liquid.
11 - Once all injected liquid has been injected, withdraw the needle slowly.
