This is one of the best products I have tried. I have suffered with endomitriosis for a very long time. I had surgery a few years back for this, but it had come back, as it normally does. I was pretty skeptical about buying anything online for this, but as I was pretty desparate for relief, I bought this product. It took a few weeks for the Endovan to start working, which is about the time frame the website said, but afterwards, the relief I got from this product has been amazing. I have been using Endovan for a few years now and have not stopped using this product. Every once in a while, I am lax and run out of Endovan, and the difference in how I feel is drastic. I am very thankful that this product is around and hope that it is available for a very long time!
