Thanks Nelson, that is useful to know.

I see I can order blood tests for aldosterone serum or urine, 17-OH Progesterone LC/MS and Progesterone.

Not sure, why test 17-OH Progesterone Vs progesterone?

Wouldn’t the end result of progesterone be aldosterone. So if aldosterone is in a good range, wouldn’t it imply that the other upstream hormones were working OK?

BTW, I sometimes wonder if my aldosterone is on the low side, because it helps to regulate potassium and my potassium is often a little high.  (this was with or without HCG, before and after TRT).  I am thinking of adding that to my next blood test.
