My DHEA was tested at 295 ug/dl. Range (138.5-475.2)ug/dl. I was prescribed 40mg of DHEA and it did nothing but make me feel worse. I don't know why DHEA makes me feel tired, fatigued, and weaker. The complete opposite of what I wanted it to do. But anyways, with my current level do I need to supplement with it anyway? I am 26. Ever since I stopped taking the DHEA a couple days ago i feel better. Maybe since my testosterone was already at good levels my body just converted it to other hormones. Im never taking DHEA again!
