sorry if this is a stupid question.
What is Levothyroxine sodium to t4(Thyroxine)
-and-
Liothyronine sodium to t3(Triiodothyronine)
since they are all thyroid hormones why do they have different names? is there a chemical called Triiodothyronine you could take thats better than Liothyronine? etc.
thanks
