so what gauge is that?
Im guessing the 23 g ...blue ones from the pic you posted in the other thread.
Theres guys using slin pins I don't know how they do it....smallest I've been able to use is a 27g and even that requires effort with my cypionate.
gauge? what do you mean? length? is that a relevant factor?
i thought it was only about thickness
in fact yes, i was wondering "how deep do i have to put this needle before injecting?"
