Your guide to 30G sterile syringes

30G is the gauge most people land on when a pharmacy needle feels too thick and a 31G feels too fragile for the volume they need to draw. This site collects what we have learned from running an EU sterile-syringe supplier — what the gauge number really means, when 30G is the right pick, and the small handling details that decide whether an injection feels like nothing or stings for an hour.

We do not sell syringes here. The articles below are the same notes we send first-time buyers when they email us with a "which size do I order" question. If you decide a 30G is what you want, you can pick up a sterile pack from our shop site, injectkit.com — but please read first. Wrong gauge for the job is the most common reason people give up on self-injection.

For a heavier-gauge alternative used to draw thicker oils, see our sister site 29-g.com. For ultra-fine GLP-1 pen needles, see 31-g.com.
