DHEA basically drops off from the age 25. The ranges for it on my lab slip go from 0.0 to something. So sure, if you have 0 DHEA in your system then your doctor will say you have enough.

Fortunately I found a doctor that boosts your hormones up to more youthful levels. I'm taking 20mg of DHEA (custom compounded, slow release, prescription type) and I'm feeling great! It really does seem to help wtih a lot of things but the most noticable one is a feeling of well-being.

7-Keto DHEA is some other form of DHEA. I don't take that.
