I had these issues as well, when disected the entire pill insides are inside this little graped sized object, undigested
Metformin XR, yes, undigested. My dr and I wondered why my A1c went from 7 to 12, well here is the answer I was not digestng the new Metformin XR. Weather done on purspose from manufacturers across the sea or due to my own lack of digesting, something is terribly wrong here. Full size of pill with insides intact.
