Buy Cytomel T3 25mcg 100tabs is the brand name for liothyronine sodium, a synthetic form of triiodothyronine (T3). T3 is one of the primary hormones produced by the thyroid gland. Unlike T4, which converts into T3 in the body, Cytomel delivers the active hormone directly.

Because of this direct action, Cytomel has a powerful and fast-acting effect on metabolism. For that reason, doctors prescribe it carefully and monitor patients closely.
