According to the numbers you've posted, you are below the lab range at .36 for your C-Peptide. So this is far from normal. I had the opposite problem - the Endo wanted to put me on insulin without checking my insulin levels or do a C-Peptide. The insulin levels were 16.9 on a 0-10 scale and my C-Peptide was 9 on a 1.1 to 4.4 scale. Adding insulin at these levels can only make my insulin resistance worse, and it did. After 3 months on insulin, my level went up to 22. Giving drugs that raise insulin levels, or just insulin, is maybe not such a goo idea for us type 2 diabetics. Isn't high insulin what causes insulin resistance in the first place? Why doesn't my Endo. know this? Probably because he doesn't care, his job is to sell drugs...
