I recently bought DHEA 25 mg from a local Vitamin Shoppe near my house. I have been taking for about for days and feel like crap. I don't think it could be from estrogen conversion because four days would be too fast to already start to feel the effects from elevated estrogen. Feel weaker and more fatigued and bloated. Any way it could be a filler in the pills that is causing this? I just ordered pharmaceutical grade DHEA from Defy and I hope that works a lot better than this over the counter garbage from Vitamin Shoppe. Also Im taking Dhea because it was recommend to me by my doctor to improve my levels.
