t know how the doctor calculated your dosages when you switched from
WP Thyroid to T4 plus T3 meds and then back to
WP Thyroid. I can explain how to calculate, if you want, but one grain of a desiccated type med is equivalent to only about 66 mcg of T4, since the AACE/ATA Guidelines say that one mcg of T3 is the equivalent of only about 3 mcg of T4.
