I also get good effects from DHEA, but IMO it should be cycled. It is great as a stand alone or even better when incorporated in PCT. I remember once when I was on it for a prolonged period of time, years ago, I started feeling pretty wierd. I had lost the "energy and alpha-rage" feeling and started feeling weak and sloppy. I almost thought that it had caused an estrogenic buildup. I'm not even sure if that is possible from it, but I dint feel as good as I did in the beginning. Once I stopped I started feeling fine again.
