When it comes to helping hormone related low mood, I don't think there are any specifics regarding the amount of oestrogen - it is more about absortion and the individual's response to a specific dose.
We are all different, absorb and maintain oestrogen levels diffently and respond differently to any HRT treatment. So while, on this forum, we share what dose we use and respond to, that does not mean it's going to be right for you. i always achieved and maintained very good oestrogen levels on quite low doses of Oestrigel - I never went above 2 pumps a day! Whereas others need 4 pumps per day to achieve the same oestrogen readings !
HRT can improve mood, even at low doses, IF the low mood is hormone related. My understanding is that high doses are sometimes used ‘short term' to either raise oestrogen levels swiftly or to shut down your ovulation to see if it is beneficial. Maintaining high oestrogen levels long term may not be good but to try a high level for a while may help with diagnostics.
You said you have had a chemo induced early menopause - have you had cancer treatment? If so, what type of cancer? Would your GP be concerned that such a high dose of oestrogen might be putting you at unnecessary risk? Have you seen your GP to discuss the treatment you are getting from the Specialist? Did you get a copy of the letter your specialist sent to your GP? GPs don't always read the letters they get from a specialist- the specialist may not have explained the full reasons for the treatment either, so the GP may not fully understand the reasons for your treatment from the specialist.
Have you found that this really high dose of oestrogen has stabilised your mood consistently?
I do think the GP is being really unprofessional in his/her approach but you do need to get the specialist to write to them again and you will also need to see the GP to discuss whether they are prepared to follow the specialists advice and, if not, why not. To deny you treatment, they must explain why. DG x
