Umm I saw them on getpinz, got some. well needles anyways..
Okay, I personally use 11/2 for gluts and 1" in thighs. I want to make sure I get into the muscle in my gluts, and my thighs hardly have any fat, and I can go straight into the muscle.
25 gauge works great for me, I also have 23 gauge just in case.
happy sticking.
