For how long does the thyroxine is stored in the thyroid follicle?

After synthesis of the  thyroid  hormones, each thyroglobulin  molecule contains up to 30 thyroxine molecules and a few triiodothyronine  molecules. In this form, the thyroid hormones are stored in the follicles in an amount sufficient to supply the body with its normal requirements  of  thyroid hormones for 2 to 3 months.
