With Thyroid -S being approx 1/5 the cost of Armour, and the increasing difficulty in obtaining Armour, I'm thinking of changing the Thyroid-s.
Has anyone any experience of changing from Armour to Thyroid-s?
I have asked before about changing form one make of NDT to another and comments posted suggested few problems switching.
Country of origin (Thailand) and cheap price just makes me wonder...probably quite unfairly!
Is Thyroid-S of porcine origin and does it have the same amount and ratios of T3 and 4?
As always, any advice gratefully received.
