Never head of these sizes? Really?ok ive never heard some of these sizes being used . standard is 22 or 23g with 1.5 length for glutes 3cc syringe.
there is nothing wrong with using the same needle for drawing and pin, nor do you need to switch needles each vial. I never heard this before. just make sure the rubber is sanatized before you draw for each. needle should go all the way in the glute- i take about 3 min to inject 2cc of oil to prevent PIP.
Trust me 25g to pin, always use a fresh needle, and you don't need a 1.5 needle ever.
