A member asked:

Could taking 5mcg cytomel (liothyronine) 1x/day in the morning possibly reduce my t3 over the day/night by messing with feedback?

A doctor has provided 1 answer

Don't do it!: All that would happen is a rapid temporary rise in thyroid level, followed by a sudden drop as the cytomel (liothyronine) was metabolized and your endogenous thyroid level drops temporarily due to the increase from the Cytomel (liothyronine). Drink a cup of coffee instead, it's safer.
