FDA-approved for hypothyroidism. Used in metabolism research, body composition, depression augmentation. Shorter half-life than T4 allows tighter titration. Caution: cardiac effects at supraphysiologic doses.
Active thyroid hormone — direct TRβ/TRα nuclear receptor binding. Increases basal metabolic rate, mitochondrial biogenesis, protein synthesis, cardiac output, thermogenesis. 4–6 hour half-life — faster acting than T4. Regulates gene expression for metabolic enzymes. Used in research for obesity, depression, hypothyroidism.
Active thyroid hormone; TRα/TRβ agonism; mitochondrial biogenesis; metabolic rate; 4–6h half-life; FDA-approved hypothyroidism.
Research data is not a treatment plan. If you are considering T3 (Liothyronine), the questions that matter are whether it suits your history, your labs and your goals. That is a conversation with a licensed physician, not a lookup.
