I did take it for a few short months following advice from a medically trained therapist, as I was unable to obtain testosterone, for which DHEA is a precursor. My problem was extreme exhaustion. I did feel better for a short time, enough to travel to the USA to see my son. I met someone there who was taking twice the dose I was and said it had given her her life back. However, the jury is out, as it has not been tested thoroughly and you must be careful who you buy from.
