NukeJohn, I also have an opinion on copycat drug makers or in my case, generic meds.
My wife took the pill which destroyed her thyroid gland which was replaced my a generic pill which was supposed to replace the hormone that the thyroid gland normally produces.
With out getting into details my wife was in real bad shape ( not life threatening)but was useless and shaking like a leaf on a tree on a windy day.
I did a lot of research and found out the quality control in generic providers of medications is poor and the dosage can very.
Case in point China would be a poor provider of Anatabloc as they care less about quality control.
IMO good things aren't cheap and cheap things aren't good.
Thyroid meds must be spot on according to a persons weight.
I also found out that many users of the generic thyroid med were allergic to a yellow dye they used.
I mentioned that to my wife's Endocrinologist and she said I forgot about that issue and she changed her med from generic to Metformin which cured the problem.
I sure wish I had know about Anatabloc before she took that pill that destroyed her thyroid gland??
