Slightly tangential to Mass spectrometry for but TomTeleRx reminded me — has the insurance landscape changed recently?

I know it is not exactly on-topic but it seems related enough to ask here rather than starting a new thread. Apologies if this has been covered — I did search first.

Slightly tangential to Mass spectrometry for but TomTeleRx reminded me — does anyone have experience combining this with metformin?

Reading this thread on Mass spectrometry for hits close to home. Night shift nurse — I started at 295 lbs and felt like I would tried everything.

11 months on tirz and I am a different person. Not just the 70 lbs lost — my energy, my mood, my relationship with food. All transformed.

If you are on the fence about Mass spectrometry — take the leap. It was the best health decision I have ever made. ❤️
