Sorry, I can't help you directly but I thought it would be useful to forum members if you posted the batch number and expiry date of the Tiromel that worked for you and the Tiromel that didn't, making clear which was which.
What I would do if I was in your situation :
1) If the T3 you aren't getting on well with makes you feel under-medicated then cut a tablet into 4 with a scalpel and add a quarter tablet to your daily dose to see if it improves how you feel.
2) If the T3 you aren't getting on well with makes you feel over-medicated then cut your daily dose into 4 with a scalpel and subtract a quarter tablet from your daily dose to see if it improves how you feel.
3) If you try both the above and don't get any benefit from either then it could be that the Tiromel is fake or it has been stored badly before you even received it. I doubt the Tiromel is fake - it costs very little in its country of manufacture (Turkey) and the effort and expense involved in making convincing looking fakes would mean there was little or no profit in it.
4) Thyroid hormones, along with many other medicines, have temperature requirements that mean they should be stored at a temperature no higher than 25 degrees C. The capital of Turkey is Ankara. The average daily maximum temperature in Ankara is 31 degrees C, but the record high is over 40 degrees C. The chance that your T3 has been exposed to excessive temperatures after manufacture and/or during sale or transport to you is probably quite high, although I should make it clear I'm only guessing.
I've been on Tiromel only for years so after a few symptoms started up again, I came looking to see if anyone had any issues. I've had palps, fatigue as well as anxiety & foggy brain and it looks like we have the same batch. It's a month since you posted but have things settled down for you yet?
Did you buy these from a known reputable supplier? Don't mention supplier on forum, but feel free to check with an admin if you're concerned that you may have been sent fake pills.
Hopefully as you say just the odd strip. I've been using the same supplier for a long time now with no issues at all and normally order six months worth at a time. I'll hold off ordering more for a month or so to make sure I a different batch number.
