<snip...imagined equivalent Armour values...>

Presumably you are talking about a US health food store (may not
necessarily apply to some foreign stores, I don't know)....
This form of desiccated thyroid CANNOT have measurable amounts
of the T4 and T3 in them; these are regulated drugs, subject to
FDA restrictions.  In other words, all your calculations can
be thrown out the window.  There may be SOME tiny (AND LIKELY
VARIABLE - - DANGER! WILL ROBINSON) amounts of T4/T3 residuals
left in them, but consider the processing that had to occur
to remove the T4/T3....yuck.  If you are seeing an endo that
has (or wants to do so) put you on some variant of the synthetic
T4, then you are already decidedly hypothyroid and would do
far better with the real, regulated/standardized drugs (YES,
this includes Armour!!); if not an endo, there are plenty of
real doctors out there that will prescribe Armour.

On the other hand, if this endo wasn't even convinced that
you are hypo, you MAY be borderline.  The only value of these
"raw thyroid" concoctions is for people that are hypo solely
due to an iodine deficiency.....NOT very likely in an industrial
country (in fact, we are often getting too much iodine in our
diets, which CAN have the same net effect of shutting down the
thyroid gland).  And then, because of the processing to remove
the T4/T3, (again: YUCK), kelp would be a better alternative
source.  My humble opinions only.
