Research Overview
MK-677 (Ibutamoren mesylate) is a non-peptide, orally active GH secretagogue that acts as a potent GHS-R1a agonist. It has been studied in vitro for its ability to mimic ghrelin signaling, stimulate GH and IGF-1 pathway activation, and its pharmacokinetic properties. Research applications include GHS-R pharmacology and metabolic signaling studies.
