I am about to make my first order and I'm making sure I have everything right. I will be purchasing amps, not vials. So, do I still need a thicker gauge needle to draw from and then another to inject with? The only reason you need two is to punch through the top of the vial, right? Also, can I just purchase 25g 1" needles? Will probably be going back and forth between quads and delts. Kinda scared of needles, so if I could get away with shorter and smaller needles the better for me. lol. I'll do what I have to, but would just prefer to make it as easy as possible for my first time. Thanks.
