Always general practitioners. I tend to just visit them when I need a prescription now. I haven’t visited an endo since I never understood the purpose: I suppose they are more expensive and I can just use the internet. My A1c is generally high threes, so I’m not sure what else they could offer. I’ve asked general practitioners and they have never been more concrete than: endocrinologists can help you figure out which pump is right for you. But, internet.
Edit! High fives, not threes. See my comment below.
