Very excited to hear of your progress! I am sure you have plenty of embryos to get you where you want to be.
But I am also curious about this concentrated form of PIO. I have residual neuropathy in both butt cheeks from all of the PIO and I would love to try less volume. (I also did better with cotton seed oil base over sesame but the nerve damage is probably more of a mechanical irritation issue).
Before you switched, did you only inject 0.5 cc instead of 1cc?
