Pre-GIC (CHX) my GP was unwilling to prescribe without guidance.
I saw Dr Curtis twice and he wrote a letter, my GP then gave me NHS prescription for the oestrogen patches. She also arranged for blood tests. When Curtis introduced anti-androgens, she balked (I believe due to their cost) so I paid privately for the first month and then thankfully this was about the time that CHX took over my hormone management and with their say so she was happy to prescribe that as well.
When I had my first appointment at CHX I had been on hormones for about 4 months and they were happy for me to continue, it took a further 6 months before they took over my hormone care.
