The proprietary injector mechanism like for Mounjaro makes it really easy for users. Even compounded versions of it use tiny insulin needles that have near zero pain when injected into the subcutaneous portion of like the stomach while pinched.

Source: I took compounded Mounjaro and compounded Ozempic/semaglutide.

Type 1 insulin user. One the alcohol should dry before the needle goes in. Two faster is better, within reason. Three about one in a few hundred shots hits a nerve bundle. That really hurts, but resolves after a short while. Both insulin and these GLP-1 injections are subcutaneous not intravenous which once a patient gets the skill it becomes like riding a bike, in that it becomes easier than imagined.

It really helps that the needles are hair-thin and short.

I concur, exactly the way I felt before and after.

Isn't there some long term harm to the skin if you do this often?
