What is T3-Cytomel?

T3-Cytomel (Liothyronine Sodium) is a synthetic form of triiodothyronine (T3), a thyroid hormone that regulates metabolism, energy levels, and overall bodily function. It is used to treat hypothyroidism (underactive thyroid), goiter, and certain cases of thyroid hormone resistance.

In some cases, T3-Cytomel is used off-label for weight loss or to enhance metabolism under medical supervision.
