The Development of Growth Hormone Secretagogues: From GHRP Discovery to MK-677 and Beyond
This comprehensive review traces GH secretagogue development from the first GHRP discovery through hexarelin, ipamorelin, MK-677, and ghrelin — covering two decades of peptide-to-drug translation.
Quick Facts
What This Study Found
GH secretagogue development spans from GHRP-6 discovery through systematic optimization (hexarelin, GHRP-2, ipamorelin for selectivity; MK-677 for oral activity) to ghrelin identification as the natural ligand — two decades of reverse pharmacology driving clinical drug development.
