Don't waste your money.
The study that DHEA manufacturers use to show that supposedly it works was performed on elderly women.
Basically, DHEA works under certain conditions - you have to be elderly, a woman and you have a to meet other conditions that were met during that study (can't remember them). Then ou will get 'some' results.
Generally, pro-hormones will give you more side effects and less results than
steroids will, all at a higher price.
