Fascinating!! I wish that they would've said what KIND of TH they used. I mean, did they use a T4 only, a T4/T3 combo, or just T3?
I am sure it is a synthetic pure T4 drug. Though the natural thyroid meds like Armour and Westhroid have been on the market for nearly 100 years with a long record of safety and efficacy the drug industry convinced doctors that pure T4 was better. Never ming that your thyroid produces T4, T3, T2, calcitonin etc if your thyroid is removed you just need T4!
