I was originally put on Armour Thyroid in late 2011, and worked my way up to 5 grains daily. In May 2012, I felt the best ever.
FT4 1.1 (ref 0.7-1.5)
FT3 4.1 (ref 2.9-4.2)
I was then prescribed 5 grain pills (until then, I had been combining 15, 30, 60, 90, and 120 mg pills), and quickly started going downhill. In November 2012, my labs looked like this on 5 grains:
It has been suggested to me that I got the "old" Armour the first time around, but I remember those pills expired in late 2012. The reformulation took place in early 2009, as far as I know. That would mean that the pills I got at first had been manufactured in 2008 already? But does NDT not have a shelf-life of +/- two years?
I have been on Erfa for the last year, doing OK, but not as great as I did on Armour the first time around. So I have been thinking lately about going back on Armour, and stick to the smaller pills. I cannot explain why I did great on it the first time around, and then went downhill, but I know this: I have been chewing the pills up all along, following the advice given in many thyroid forums, and I cannot remember any Armour pills tasting sweeting and being crunchy...
It's all pretty confusing. On some thyroid sites, Armour gets 9 or 10 stars out of 10. On other sites, it gets 1 or 2 stars...do all thyroid drugs affect users so differently, or is it just Armour since the reformulation...?
