I found DHEA in the natural aisle of local grocery store under $10. I take a low dose daily (in my early 30s). Worth researching.
(I didn't down vote you.)

I understand DHEA as a steroid hormone that is a precursor to testosterone. I consider the drug's banned status in athletic competition as a signal it might be effective.
From Wiki: "DHEA is legal to sell in the United States as a dietary supplement. It is currently grandfathered in as an "Old Dietary Ingredient" being on sale prior to 1994. DHEA is specifically exempted from the Anabolic Steroid Control Act of 1990 and 2004 It is banned from use in athletic competition."
My Google foo is failing me, I can't seem to find an actual report, just news articles. Help a fella out with a link?
