Maybe I'm just thinking too much...
Here in Australia we have only three Strengths Available
(50mcg, 100mcg & 150mcg)
(25mcg, 50mcg, 75mcg, 88mcg, 100mcg, 112mcg, 125mcg, 137mcg, 150mcg, 175mcg, 200mcg & 300mcg)
I wonder if studies were done - if there would be any similarity in dosage between countries for equivalant thyroid conditions?
