Summary

Do 1 inch needles thinner than 25g exist for IM use without bending too much?

Users confirm 27g and 30g 1 inch needles are available from various makers. Several note that anything thinner than 25g becomes very bendy for IM shots into muscle, while one person reports success with standard 25g 1 inch on oils. Others point out that thinner options require much more thumb pressure to push thicker liquids through.

What this discussion establishesWhere people disagree

Whether a gauge under 25g is practical for typical IM oil injections or if it simply trades insertion pain for injection difficulty and bending risk.

Still open

Exact minimum gauge that still works reliably for IM without excessive bending or force.

Nothing here is advice.

Hey everyone, I'm after a needle in the 27g to 29g range that's a full inch long. Do those even exist? The finest I've seen so far are 25g and I'm wondering if the longer ones have to be thicker to stay straight.

Are these for mixing? You can get 25g at an inch and a half or 30g at one inch from regular sources. They flex a fair bit though. Not sure how well that works for muscle shots.

Needle size uses the gage system where a higher number actually means a smaller diameter.

I wouldn't pick something that narrow and that long because it will flex too much. I just use 31g short ones for mixing and for shots. Stoppers can sometimes fight back and the needles bend a little then too, so I just grab another.

I should have said this is meant for an injection into muscle.

LevelTimber64archiveFeb 10

In that case I can't really help, sorry.

I stick with 25g one inch for muscle shots with oils and haven't run into problems. Going thinner like 31g just raises the odds it will bend, so if anything you'd want to go thicker like 23g or 21g instead.

Curious whether the people who complain about tone get the same kind of notice or if the moderation only goes one way.

Anyone who keeps ignoring the rules and other users ends up dealing with warnings until they change how they post or stop coming around.

Does the same apply to brand new people like me? I understand the point and just want to avoid any issues.

Exactly, the same standards apply to everyone.

A few brands make 27g needles at one and a quarter inches, and at least one makes a 30g at exactly one inch.

Thanks. The real issue is I keep hesitating right before the shot and then it ends up hurting worse because I end up pushing harder. I was hoping a smaller gage than 25 would make it less painful going in, or maybe I just need to commit to the motion instead of second-guessing.

Both 27g and 30g are finer than 25g. For the shoulder, half an inch is usually enough to reach the muscle once body fat is low.

Be careful what you ask for. I tried one inch 30g on a different compound and the injection itself didn't hurt, but forcing the liquid through took so much effort that my thumb was sore afterward.
