Hi -- I am on a whoppingly tiny 14 mcg a day, time release, spread out over two doses of T4.
I couldn't even take the 25mcg of either T4 (synthroid) or Armour without being way way way too speedy.
It has worked!!! I started, very very slowly at 6 mcg in April. It took over a month to get up to the 14mcg. My health insurance won't cover it because it is considered alternative therapy because it is so darn low.
My TSH level is now at 4.44 from 11 in April.
