There are synthetic T3 medications too. Cytomel is the most commonly prescribed. The Mexican version, Cynomel, is available cheaply and is of high quality. The same brand, Grossman, also does a product called Cynoplus with both T4 and T3. As far as I know, these products don’t have any junk fillers.
Some people require T3 on top of dessicated thyroid to eliminate symptoms, and in some cases need to avoid T4 altogether. Armour used to be pretty much the best, but it doesn’t resemble what it once was, due to new processing methods. Many people have complained about recent batches. Symptoms/labs are the best guide to what you need.
