I don't think that trials were run to prove that Synthetic drugs are
superior to natural thyroid replacement when they were introduced.
So here's the challenge to the makers;
PROVE IT by supplying the evidence, details of the studies, outcomes
and dates please. Prove to us here that I am wrong, because I know
what I see, week in week out, in the thyroid newsgroups.
Make the studies accessible to doctors all over the World by re-publishing
the results, they NEED looking at objectively.
