Want to share my personal experience related to Beyond-use dating 28 days vs since I think it might help others in a similar situation.

I started my GLP-1 journey in October 2024 at 260 lbs with prediabetes and hypertension. My endocrinologist prescribed semaglutide 0.25mg to start.

Now, 16 months later: I am down 35 lbs, my labs have normalized, and I am off 2 of my 3 medications. The Beyond-use dating 28 aspect specifically was something that made a big difference in my journey.

This community helped me every step of the way.
