slowly drip the AA down the side of the glass vile until 1 ml is emptied into it. Store it in the fridge and when you need to use, do 4 to 1 BW to AA. For example I use 100 mcgs per shot so I would suck up 1/10 of an ml of AA and then suck up 4/10 of BA. Total on a 1 ml syringe would read5/10 or up to line 50 on the syringe in simpler terms. Do not mix the BW and AA together until ready to inject.
