So now my Endo orders an acth test. I asked him about it and he said it is to check if I have adrenal insufficiency. And added that if I did he would give me a medicine,but not hormones ,cause he does not believe in hormones. My cortisol was 7.5 on the low side ,but within range. My free test and bioavailable test were 63.5 and 120, he stated they were both fine.He seems obsessed on the cortisol though that night I had bad sleep ,plus took melatonin.
