7 keto DHEA is working for me as well. At first, I thought that I was experiencing a placebo effect. But after using the product for many weeks, I stopped using it for some time and saw the positive effects go away when I was off of the supplement. So I have used 7 keto DHEA long enough to know that it is helping. I have better energy, better memory and better mood. It also seems to reduce sugar and carbohydrate cravings that I experience.
I have used regular DHEA supplements in the past and those certainly had some negative side effects. In contrast to 7 keto DHEA, regular DHEA supplements worsened my mood and made me very irritable. That's why I didn't like them.
