m not sure what you mean by 25mcg/5mcg of
cytomel. Synthetic
T3 medications, typically, come in 5, 10 or 25 mcg tablets. I, typically, recommend getting the 5 mcg tablets, no matter what your total dosage is, since it's easier to control/split dosages, without having to split pills. It's recommended that those of us on T3 medications split the dosage in 2 during the day in order to keep T3 levels stable throughout the day.
