First time I told my family dr I was using she had no idea what I was talking about lol. Only thing he/she can do when you told them is help you with whatever you need man. They are not out there to judge you, I always think it's a good thing to talk about what you are using.
In my case I just asked her to see an endo, then I never saw her again haha, there are not specialized at all, but it can be a good way to get blood work fast if he/she understands
