What is T3 Liothyronine?

Liothyronine (T3) is the biologically active thyroid hormone — 3-4× more potent than T4 at thyroid receptor binding. Directly activates TRα/TRβ without peripheral deiodination. Research: metabolic rate regulation, thermogenesis, thyroid receptor pharmacology, hypothyroid models. CAS 6893-02-3.

Research Applications

Thyroid Receptor Pharmacology

Direct TRα/TRβ activation — no deiodination required

Metabolic Rate Research

BMR upregulation — mitochondrial uncoupling, thermogenesis

Hypothyroid Models

Thyroidectomised rodent T3 replacement and dose-response

GH/IGF-1 Axis

T3 permissive effect on IGF-1 — GH axis interaction

T3 vs T4 Comparison

Active vs prohormone — direct pharmacological comparison
