Menomale, I think you and I are the only MM members taking DHEA. I agree there aren't many studies/articles on DHEA but I don't care because like you, I take it at my own risk and I am effectively carrying out my own study.
I have been very impressed so far and definitely feel better and have more energy. I have been taking 25mg everyday for over a year and have starting producing my own hormones again, namely, oestrogen, testosterone (confirmed in blood tests) and probably a small amount of progesterone because my periods are lighter. My gynaecologist suggested I reduce my dose to 10mg everyday but I had a couple of migraines while on the Utrogestan phase so the migraine specialist told me to increase back to 25mg and I have not had another migraine since.
My observations are not based on anything scientific but I have a hunch that in my case, producing my own hormones gives me a greater resistence to artificial progesterone (my only migraine trigger) and keeps the migraines away and possibly makes me feel better overall.
So it's really down to the individual to decide whether or not to try it but in my opinion, there is nothing to lose by giving it a go and if it doesn't work out, you can just stop taking it.
You should not take DHEA if you are post menopause unless you are taking HRT or have had a hysterectomy because it will cause womb lining to build up.
I look at it this way, synthetic progesterone and high doses of Utrogestan (which, incidentally is where all the risks of HRT lie) has a horrific effect on my body and triggers silent migraines that consist of a blind spot followed by 25 minutes of visual disturbance that make me virtually blind. This means there are a whole host of jobs I would not be able to do and who knows what damage it could do long term. How can DHEA possibly be any more harmful than that?
Note: these are my own personal experiences and others may have very different experiences while using medication mentioned in this post.
