It says for research only!! So.... is it safe to use or would I be part of an experiment if I use the hypothyroid "Thyroid S" product?
Yes it is safe, lots of people are using it. That warning has to be there by law, big pharma have made it so that people have to buy medication through them, and their stuff is all synthetic. No one here is offering you medical advice. You have to research these things yourself, everyone is responsible for their own decisions, no one else can make them for you.
Where do you buy it from?
my adam's apple is very thin.
As a vegetarian, it is important for me to know, is this on synthetic medication made from the thyroid glands of animals, as is synthroid?
I don't know what chemicals they use to make the synthetic stuff, but I do know that it isn't supposed to be effective. Natural is always best, but I realise this is probably not an option for you.
