I performed a modified variant of the Goldfarb protocol wherein I used bio-identical hormones. Very large estradiol injection every 3 days. Daily progesterone injection. Progesterone suppositories overnight. I was able to get my estradiol and progesterone levels up to about 2nd trimester levels and held them there for 3 months.
My results were incredible. I notched 935ml at peak, and this was with a very lazy pumping schedule of 3x per day and an unenthusiastic partner.
I thought I had failed when my milk failed to come in, but it just took like 6 weeks for my estradiol to come down from all the injections. In hindsight I would have tried just doing 1 month and seeing how much I got, because the physical changes seemed to have stopped after a month, and the injections were a lot. Plus, that much milk was kind of overkill for my needs, although I did get to feed a gay couple’s baby for a few months, which was cool.
