T3 in the UK

[OldManUK]

Good morning everyone, I've been long time lurker.

My thyroid hasn't worked for over 30 years and am on NP Thyroid (before that RLC Labs). At the moment I import my usual NDT and it's costing an absolute fortune. I'm trying to find somewhere online that I can buy a small quantity of T3 to see how I get on with an extra small supplement to what I'm already taking, is it possible someone can help via a private message?

I appreciate any help from you all
