  == Verifiable sources for Desiccated Thyroid Extract article ==  Hi, I noticed you contributed to the Desiccated Thyroid Extract article.  I am working on improving it for readability and usefulness.  I am having a difficult time finding a verifiable source for the drug ingredients of all three brands (Westhroid, Naturethroid, and Armour Thyroid) of desiccated thyroid extract.  In your opinion, would information from RLC Labs (the makers of Westhroid and Naturethroid) be considered a verifiable source? Your feedback would be greatly appreciated.  Also, if you do not have time, could you refer a few users that I may ask?   Thank you!
