I did get a boost from DHEA but I won't take it now because:
1) I have huge fibroids and DHEA should not be taken when fibroids are present
2) DHEA will eventually suppress cortisol
1mg of DHEA is a very low dose so it's hard to know if that will have any effect on your cortisol levels.

I take DHEA in a transdermal cream, 25 mg, once or twice a day.
It has been proven to increase sense of well being in those with adrenal insufficiency in several studies. It also increases bone density and may be protective against breast cancer.
Fibroids are too heterogenous of a condition to make blanket statements about whether or not DHEA or estrogen treatment is appropriate for any individual. Some fibroids will worsen with estrogen, some with progesterone and in some cases there will be no effect. It's a decision to be made with an experienced practitioner.
It's easier to say that no one with fibroids or breast cancer should ever take HRT but the truth is much more nuanced and individualized.
I've never seen a scientific study that has found DHEA to lower or suppress cortisol once it is already low. If it did that, it's unlikely that it would be helpful for those with adrenal insufficiency.
If you want to try DHEA, just be mindful of side effects and watch your labs to keep it in a healthy youthful range. I aim for 300-400 ug/dl.
