Iam using 23gx1 in pins in the glute. i have done my first injection this past monday and everything was fine.Is the shorter needle doing the job ok or do i need to get 1.5 in.Just wondering. Also is it ok just to shoot test e at night or does it have to be for instance monday moring thursday night or would it still be ok if i pined monda night if i just pin tonight (thursday). thanks
