Under 300 is low thats what most doctors will tell u, between 600-800 would be ideal to some people, I'm talking TRT levels, while some others want to be 1200-1500. But remember the higher the levels the more sides you will be getting like E2, hemocrit/hemoglobin. I was 198 when I first got tested. I would recommend u to read, read and read about the options you have, like if u want HCG, Aromasin-Arimedex, etc. the more informed you are the better.
