Hmmm, there's a lot of questionable doctor stuff going on in this thread(!).
Madge79, Lenzetto is quite a 'weak' form of HRT, dosage wise - you need a lot of it. And I've also heard that bloods are not reliable because of the way it is stored in the skin which can affect blood tests somehow. So you might need to switch to another product but just a lot more of it, or to try the oral HRT (only problem there is the estrogen is a fixed dose so if you do need more you can't increase unless you add some transdermal in).
And merrygoround, I'm not sure what you mean by the highest dose you were 'allowed' to try was 3 pumps of gel... 4 pumps all GPs should be quite happy for you to use, and the NICE guidelines say you should be allowed to increase to that if symptoms need it - which it sounds like they did for you. Many women need more than that and your option then is either wait ages for an NHS menopause clinic or go to a private clinic like Newson.
I am on TEN pumps of Oestrogel at the moment, 5 pumps in the AM and 5 pumps in the PM and my serum estradiol is around 430pmol. I probably need to go higher still, as I get night time symptoms.
My Newson doctor says most women need to be between 400-600pmol for symptom control, especially during peri-menopause. My NHS GP has been happy to prescribe me this dosage with the letter from my Newson doctor to say that I need it.
Don't forget that most HRT was designed to get women around 250pmol in post-menopause, so if you need to get much higher than this for symptom control in peri you may well need quite high dosages - even aside from the 'poor absorber' issues. ALL GPs should prescribe up to the max licensed dose which is 4 pumps of gel or 100mcg patch. If your GP is reluctant to prescribe more than this, IMO the best route is with a letter from a private menopause clinic to the GP to tell them to prescribe higher. You still get the meds on the NHS.
