some places sell needles separately, so i usually buy a box of 22g 1.5" syringes, and also a bunch of 25g 1" needles. you will be there all day trying to draw out of your vial w/a 25g needle. also, the 1.5" will reach the bottom of my hcg amps to draw out of them. if im shooting glutes i will usually leave the 1.5" on, but lately i've been doing quads, and after filling the syringe, i put the 25g on to inject. if you are going to inject w/the 25's only, i would even buy 21 guage to fill cause it's a lot quicker.
