I would second BR advice esp with respect to the quantity used in females where the starting dose would be half of what he opined.
In part bc although thyroid supplementation does result in lipolysis the cost is SKM catabolism once higher supra-therapeutic dosages are reached.
(On a comparative basis I believe it helps to understand the typical replacement dose of SYNTHROID is 20mcg/day.)
Finally those who have a HX of "anxiety", palpations, or ANY known arrhythmic disorder should absolutely avoid thyroid supps or the beta agonist class of drugs IMO
