I know you can buy it from iherb without a script but I haven't personally. I'm in it and I have got pimples from it! As far as I know research has shown no significant improvement in egg quality with the women in the study which is why most FS don't support its use. My opinion is that it doesn't hurt to try it. Just be aware it raises progesterone so you might have late periods on it or out of whack cycles. Don't take it during ivf stimming, egg transfer, tww etc as it can raise progesterone and affect your ivf cycle.
