t4 is march 2018 & t3 is april 2018. what other thyroid products have you tried? i mainly use thiroyd, but i don't want to but my tsh tested low on it & i had normal t4 but low t3.
I have tried a lot, some I can remember from over the years:
NDT: Thiroyd, TMAN, Armour
t4: Synthroid, Levothyroxine, Aspen Eltroxin, GSK Eltroxin, Thyronorm, Grossman t4
t3: Grossman t3, Tiromel, Uni Pharma, Thylexan
NDT didn't work for me at all, in fact made my symptoms a lot worse.
T4 alone worked well for me at the start then stopped working
T3 only was a disaster
T4 & T3 is what I take and is the best, I would say BSP is the best of all of these, I think a big part of it is the lack of the fillers and better absorption compared to tablets. I can feel a difference in all the different medications I have tried, some have side effects more than others, some don't work (most t3 on the market).
