I actually just ask because I have some gyno.
Let me tell you I've purchased more Letro than you all combined. You won't reverse it.
I've reduced it only with 20mgs 3 times daily nova. It comes right back.
I've reduced it with nova, then hopped on letro, then back to clomid to help with the rebound. It's the same.
To be honest, I think a lot of the "myth" is created to sell liquid Letro. It worked for me.
It cost 6k to get it cut out. Why not drop $600 first if it might work?
