Score amps if not already scored. ... a fingernail file or knife will do the trick.
From open the one with liquid and be sure not to spill it.......suck up the liquid into your syringe..i 0rder my syringes with 21 ga 3" darts cuz they are easy to draw with.
Add slovent to powder.....swril around until it is fully dissolved.....draw mixture up into syringe, change needles to like a 25 Ga 5/8" or 25 1", Swab Skin with Alcohol, and bang it into the muscle, asperate, push it in. Done.
