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
