Just search google, and you will find many links
For example http://www.abundalife.com/dhea.html
DHEA is being investigated and may eventually be approved by the Food and Drug Administration (FDA) as a prescription drug for treating systemic lupus erythematosus (SLE) and improving bone mineral density in women with lupus who are taking steroid drugs for treatment. The FDA is still studying the pharmaceutical company’s application for approval.
What got me onto it was that previously, after taking 75mg/day of steroids for a few days, while taking calcium supplements, I noticed I was literally urinating calcium! and even in small chunks!
By chance, I was trying DHEA as a general health thing, when I noticed that when I also did the prednisone, my urine was clear of the cloudy calcium.
That was where DHEA could be taken without prescription. Anyway, back in Australia, you need a prescription, and get it made up by a compounding pharmacy. One time when I went to get the DHEA, the girl sheepishly asked why I was taking it. I explained the calcium thing and she smiled knowingly, and told me my Dr was way ahead of the pack, as they had just been commissioned to create a batch of tablets for a large study at one of the Hospitals, for that exact purpose.
