T3 does speed fat loss. As a guideline, for most 12.5 mcg/day is a
conservative "supplement" sort of dosing that seems to have no
detectable adverse effect on thyroid function at all.
25 mcg/day is a "supplement" sort of dosing that does have some
50 mcg/day is a reasonably conservative bb'ing sort of dose that,
of course, is more inhibitory.
75 mcg/day is getting into more of a problem area;
100 mcg/day in many cases leads to loss of muscle size and
These doses are in reference to legit T3 provided in tablets such
as Cytomel. Liquid formulations are usually unstable and as a
result, the above numbers in many cases won't match up to
experiences with liquid products, or for that matter, experience
with a liquid product at one time may not match up with experience
at a different time, due to the stability problem.
Individuals do vary in this but 100 mcg/day is very often quite
weakening and muscle-catabolic. So far as wanting more rapid fat
loss than what is achieved with 50 mcg/day, personally I'd look
elsewhere than adding more T3.
