Really wouldn't recommend Gender GP, I know she's quick and gets things done but it's not even legit service Nd she's got no gender specialism, neither does her husband who has currently taken over while she's not been allowed to practice. I've also heard that some guys after having gone with webberly and then to a GIC found the process for them to take over your care is longer because they count going to webberly as self medicating. Obviously it's completely your choice and if you need care then contact her practice but she's a complete rip off (£30 a month service charge, 300 odd quid an appointment and you're still paying private prescriptions).
Better options would be contacting gendercare in London or YourGP in Edinburgh and seeing what they can do for you. Still private services but a lot more legitimate and they work with the GICs. I'd also recommend switching GPs to one that will accept shared care, as long as you have all your paperwork from Dr Curtis you should be able to show the GP and ask if they'll accept shared care, take over your bloods and ask if you can be referred to a local endocrinologist that can monitor you.
