I have only recently come across this organisation. The following is from the front page of the website -
THYROID PATIENT ADVOCACY (TPA) is an independent user-led organisation established to ensure that all thyroid disease sufferers are given a correct diagnosis and receive effective treatment. TPA believes all patients should have access to all relevant tests and treatment, including synthetic or natural T3.
As a result, TPA campaigns for better education in diagnostics and treatment and provides extensive support and guidance for all sufferers.
TPA is managed by a group of dedicated thyroid patients who volunteer their services freely. The web site, the TPA-UK Information Pack and the Internet discussion forum is available to all and will help patients and doctors develop greater knowledge and understanding about the illness, will advise on reliable diagnostic tests, and recommend where to obtain proper, effective treatment.
