27G x 1/2 VS 25G x 5/8

Switched from IM to SQ a few months ago, been using 25G x 5/8 insulin syringe at 90 degrees in my incredibly fat belly. Specifically, between 2-4 inches away from the belly button on either side. The way it “feels” and how quickly i react to it, i think im actually doing a shallow IM...like im...

5/16 needle in deltoids

Needle Length - Is 5/16" Long Enough?

For more than a year now I've been using 28g 1/2" needles. Recently, I've been using 30g 1/2" needles and like the smaller gauge, mainly because I rarely get any leakage of oil from the injection site when using them. Lately, I've thought about going to 30g 5/16" needles. I inject SubQ in the...
