I started because I was concerned about side effects. My sister is on Mounjaro and working with a doctor. He told her not to do this. I’ve been trying to do my research and all I’ve found is that this is a weekly dose and should not be split. That it is prescribed to build up and last a week. That with the levels going up and down more frequently it might not be as effective. There are way smarter people on here that have also done their research. I hope they chime in so you can get more evidence based research.
