I have never posted on here before but here goes....!!!! I have recently seen an endo who has prescribed me a T3 / T4 combo to treat my somewhat wobbly hypothyroidism. He wrote to my GP asking him to prescribe this for me (after I had paid for the first months worth from the chemist at £218) and the GP has refused as "it is not in the formulary". I now know that I have to source the T3 from somewhere else but am really scared that buying from the Internet could be dodgy. So I wondered if you knowledgable people could please offer me some advice before my 14 remaining tablets at approx £8 each run out!!!
