I know Endovan works. I couldn’t conceive for 20 years due to a cyst on my ovaries and pcos. I was in a lot of pain. After one month on Endovan my pain left. I had an ultrasound and now they only see a small cyst – no pcos, the doc says the pcos is gone! I will take this product long as i live, if i continue to take it i know the small cyst will be gone and i will conceive.
