MK-677 is a growth hormone secretagogue that mimics ghrelin activity and is widely discussed for its ability to support natural growth hormone (GH) and IGF-1 levels without being a peptide.
It is commonly explored in research and performance contexts focused on recovery, sleep, and muscle development.
MK-677 operates through ghrelin receptor activation:
• Mimics ghrelin to stimulate GH release
