Slightly tangential to Amino acid analysis for but Dr.GutHealth reminded me — does anyone have experience combining this with metformin?

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.

Reading this thread on Amino acid analysis for hits close to home. Dad of 2 checking in — I started at 293 lbs and felt like I would tried everything.

9 months on tirz and I am a different person. Not just the 68 lbs lost — my energy, my mood, my relationship with food. All transformed.

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