From my experience, these herbal/pro hormone AI's that you can buy in the store don't do shit for your estrogen levels.
Just don't even waste your money on them!
NOTHING beats exemestane for reducing e2, reversing gyno, and keeping your lipids good.
Only reason I even considered it is because of the success I've had with erase. A buddy of mine turned me on to it and he's been running so long that I'm surprised he's not dead yet. He's started talking about this estro strike like crazy here lately and I dont like jumping into anything without researching it. So far the only people I know of that have even tried it are not running gear but ph. Just wondered if anyone in our world has tried it.
