I've been transitioning to T3 only as I suspect RT3 overload. I had been on T4/T3 combo until June and then a month or so before I went T3 only had been using NDT - felt like champagne compared to homebrew! - however I had some UK prescribed T3 which I was using and I'd noticed how on NDT and the original T3 only I had no headaches. However one of my T3 doses is currently from mexico and is cytomel and I've noticed an increase in headaches again since introducing it.
Has anyone else noticed something similar and can anyone suggest any other brands and how to source them please? Thank you as ever.
Recommendation where to source T3 via private messages please in line with posting guideline #22, thank you.
