Help PFS'ers exhaustion

How did you dose your hydrocortisone?

Iā€™ve done urine where it said I was within range even though it was low for salivary tests

Same here, but dosis were a bit different for me.

Salivary tests are really unreliable. A lot of pseudoscientific websites promote them because they are easy to do, they make money off them, and they give people a sense that they have learned something. But though a bodily substance may be found in saliva, does not mean that the level of it in saliva has any relationship to how well the body is functioning or not.

Thatā€™s what a lot of doctors have told me, alongside that my pfs isnā€™t real

Doctors may be ignorant of PFS and other diseases, but that is different from saying a particular test doesnā€™t do what you want it to do.
There are blood and in some cases urine tests for specific hormones or hormonal problems.
Do you want a list of the most common tests used to detect abnormalities that can be caused by PFS?

Sure
