Yes, as part of ongoing testing have had a few dexamethasone suppression tests. Have always suppressed. Anywhere from moderately to significantly. Last dex suppression test was a result of a 1.2 ug/DL.

One type boosts the adrenal glands and could actually increase production of cortisol while other type is an effective "anti-cortisol" product. Can't remember offhand which is which. Let's see, something like non-deglycyrrhinized licorice and deglycyrrhinized licorice, but can't recall which does which (darn brain fog!).

But, rather than increasing cortisol production, literally, it inhibits the conversion of cortisol to cortisone, via the enzyme 11beta-hydroxysteroid dehydrogenase type 2. This actually enhances the systemic cortisol signal, and shuts down the adrenal gland production, via cortisol receptors in the hypothalamus. This sounds contrary to what you seek, but:

The results indicated that treatment induced dose-dependent and mostly significant decreases in the concentration of cortisol, ACTH, aldosterone and K. There were concomitant dose-dependent increases in the concentrations of renin and Na. The results suggest a strong and dose-dependent suppression of the adrenal-pituitary axis, accompanied by stimulation of renin production from the kidney.

On its face, it sound like it has a very similar mechanism of action as does licorice, except I don't know if licorice antagonizes the GR receptor. You'll note in your last reference that mifepristone has the short term effect of increasing cortisol. So would licorice. The idea, I suppose, is to shock the sytem back into a more normal "rhythm", like shocking a heart that is beating too fast. I suspect the short-term increase in cortisol ought to be seen as a side-effect of the therapy. The true intent is to get the hypothalamus back into balance.

Am even still trying to take 1/4 tablet of Tyrosine without too much stimulation (especially in the result of having the prostatitis type pain - burning urethra - flare up and the anxiety feelings enhance somewhat). 1/4 tablet is 125 mgs in my case (maybe I need to find 100 mg tablets and cut them down??? or maybe just let go that angle for right now and assume that I've actually got more than sufficient dopamine / adrenaline levels???).
