B-12 injections

I'm going to start B-12 injections, what size needle do i need

b-12 is a thin and like water, will go through a slin pin no problem. I usually use a 25g with it though.

but are you wanting to shoot IM or sub-q?

i use a 25g 5/8 needle for b-12 injections. stuff loads and injects easy!

i use a slin pin and shoot sub-q....works great

25g 5/8 SQ
