Yaaaaaay Postmeno3! That's great news. Well done for hanging in there.
There seems a general theory that Lenzetto is weaker than other delivery methods? Not sure.
I certainly felt like I was getting poor absorption from it compared to Estradot patches & when I read around on the web there was the suggestion it was weaker than originally thought,
but quite a few members report doing well on it & it seemed well worth your trying it as we all respond differently - it was a different application site & a different mode of delivery to any you'd tried before. It's so easy to use & dries so quickly I have HRT envy

Yes - do try the testosterone. I think you've told us you have only 1 ovary, so I can't help but think T deficiency has been part of the problem. If it doesn't help & you still feel worse on oestrogen replacement than you did before resuming HRT, at least you'll know you have tried & you can then move on.
Everything crossed for you.
