Interesting, me replying to someone who wants DD's, as I am the opposite of that. Nonetheless, I do bi-est and progestérone daily.. in small amount. No idea what results would be if I used stated amount on pump. Point being, you could titrate your dosage up, as you carefully gauge the effects, and you would be using a nominally bio-identical hormone, rather than a plant estrogen analogue. Interesting to learn the difference in results, between PM and bio-identical. I also use saw palmetto, DIM, and a few other 5-AR blockers, to keep DHT low.
I report no ill-effects, only healthy ones. It would be interesting to hear what your results might would be, at greater dosages than what I use.
