Sourcing T4 and T3 help please

[Louise1610]

I currently get 50mcg levothyroxine from my NHS GP but I have been supplementing that with another 50mcg levo and 25mcg liothyronine that I source myself. My GP has recently declined to keep providing that 50mcg levo because the local endocrinology department says that I must get all of my medication from one place or another.

My option was to source all of my medication separately or to go through the GP/endo for everything, but that would mean stopping all of my liothyronine and simply taking 50mcg prescribed so that the endo could see how that impacted my blood results and they could decide whether I do actually need T3. I said that I really wasn't prepared to cut my medication so drastically so the GP has now said that they can't continue prescribing to 50mcg levo anymore unless I agree to their plans. They refuse to agree that I am not overmedicated.

I currently have 1 source to get T4/T3 but I would like some recommendations of where else I could source these from as I'm conscious that if that source stops providing their services, I would have nowhere else to go.

For context, on 100mcg levo and 25mcg lio, these are my latest NHS blood results done on 14th November giving 24 hours since last T4 dose and approx 12 hours since last T3 dose:

TSH: <0.01 mu/L (0.35-4.94)

Free T4: 11.1 pmol/L (9-19)

Free T3: 5.1 pmol/L (2.40-6)

I know my levo result could do with being higher, so I've increased my levo to 125mcg (which I was on before I tried reducing to comply with the GP's request) and will recheck my bloods to see if I still need a bit more.

Please can I have a couple of recommendations for sourcing both T4 and T3 please? I understand that this must be by private message and I am to double check any recommendations with admin before parting with any money
