Description:
MK-677 (Ibutamoren) is a non-peptide growth hormone secretagogue and selective agonist of the ghrelin (GHS-R1a) receptor. Unlike peptide-based secretagogues, MK-677 is orally active and resistant to enzymatic degradation, making it a widely studied compound in pharmacokinetic and endocrine signaling research.

In experimental and preclinical models, MK-677 has been used to investigate ghrelin receptor–mediated pathways related to growth hormone pulsatility, insulin-like growth factor-1 (IGF-1) regulation, appetite signaling, and sleep architecture. Its well-documented oral absorption profile has made it a model compound for studying bioavailability, dose-response relationships, and long-term receptor activation effects in research settings.

Due to its stability and extended half-life, MK-677 is frequently utilized in studies examining sustained endocrine modulation, circadian hormone patterns, and metabolic signaling under controlled laboratory conditions.
