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.
Do you still take it? I'm looking for some more information on compounded GLP-1 and their safety.
Similarly, I grabbed one of the over-the-counter CGM biosensors (Stelo) to gather some data for a couple of weeks and the initial fear of "holy hell, I'm slamming a needle into my arm with something stuck to it" goes away as soon as you slap the injector release.
Just one little clap sound, you feel a little pat on your arm, and the sensor's already made it where it needed to with no pain.
When you remove the sensor it's a little bit of a shock when you see the sensor wire and realize just how small it was and how you never felt it run around inside your arm for a couple weeks.
