Liothyronine (T3) and MK-677 Interaction

Monitor
Mechanism-based 51% confidence

Liothyronine (T3) and MK-677 have an interaction requiring monitoring for interaction with 51% confidence. Both Liothyronine (T3) and MK-677 can raise blood pressure. Monitor BP regularly and consider adding cardiovascular support (cardarine, telmisartan, or similar). Both compounds affect the gi tract, so monitoring these systems is recommended.

Compound Profiles

Liothyronine (T3)

Thyroid Hormone | Metabolic Optimization

Liothyronine enters target cells via monocarboxylate transporter 8 (MCT8) and other thyroid hormone transporters, then binds to nuclear thyroid hormone receptors (primarily TR-beta in metabolic tissues and TR-alpha in cardiac tissue). The T3-receptor complex forms heterodimers with retinoid X receptors (RXR) and binds to thyroid hormone response elements (TREs) on DNA, directly modulating gene transcription.

MK-677

Ghrelin Receptor Agonist | Oral Growth Hormone Secretagogue

Selectively binds GHS-R1a receptors in hypothalamus and pituitary, triggering pulsatile growth hormone release while maintaining natural circadian patterns..
