I used Lenzetto about 5 years ago and although I liked the fact it was very user friendly, I found it too weak and my symptoms returned even though I was using 3 sprays every day so I went back to Oestrogel. To give you an idea, 3 sprays of Lenzetto gave me slightly lower oestrogen blood levels than just 1 pump of Oestrogel.
I think 100mg Utrogestan every day is too much progesterone for such a low dose of oestrogen so that is probably why you are not feeling any relief. I would definitely increase the Lenzetto first and if that doesn't work, try a different form of progesterone.
Utrogestan might be body identical but generally speaking, it is not well tolerated and has a lot of side effects, more than some of the synthetic forms of progesterone in fact.
I take it you have regular TVS scans with your history of hyperplasia?
