Slightly tangential to GIP receptor the but Dr.KarenChen 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.

Follow-up question: how long did you wait before increasing your dose

This is exactly right. PeptideSynthNJ articulated what I have been trying to explain to my doctor for months. The GIP receptor the aspect is the most important factor.
