Here we go again.
Your idea is a lot better than some of the ideas I see like 2.5mg/d. 1mg a day is probably too much, too, but it is not quite as insane as some of the things I’ve seen.
Yes, I have firsthand knowledge of this. No, you don’t want to do it to any sort of extreme. Dropping estrogen too low is absolutely miserable, both physically, but a lot moreso, psychologically. Completely eliminating the libido is a lot worse than it sounds, believe it or not. It is a very hollow, dead feeling, and one I would never again want to revisit.
Now, IF your gyno is REAL gyno, meaning actual hardened breast tissue that is palpable and usuallly located beneath the nipple, then lowering your estrogen to just below normal levels for a time may serve to shrink the tissue down to an unnoticible degree. It doesn’t have to be letrozole, believe it or not, and the dosage does not have to be extreme. You just need to get estrogen low enough so that activity at the estrogen receptors at the breast tissue is reduced enough to cause that tissue to shrink. I have real gyno in my left nipple and if gets bigger and smaller as my estrogen goes up and down. It’s actually a pretty damned good indicator of just where I’m at. It has been pretty damned big before, like the size of a small grape, very noticible. Now it is not noticible at all, and I can hardly tell its there even when I palpate it.
Thing is, I THOUGHT I had gyno before. But I didn’t. It wasn’t until I REALLY got gyno that I actually got to appreciate what it truly is, and, strangely, I stopped worrying about it so damned much after that, too. It’s a bit beside my point, but if your gyno is real and pubertal, I don’t know how much letro could help you, as your natural estrogen levels are just going to creep back up again eventually, and with it I would imagine that breast tissue would regrow. And if it’s not real gyno, and it’s just fat under the nipple, then no amount of any kind of AI is going to do a damned thing for you.
My advice would be to start at 0.5mg/d and stay there for a week, monitoring yourself carefully before choosing whether or not to increase your dosage. And yes, certainly taper down SLOWLY when using letrozole.
Good luck.
