§ 02 — Abstract
An orally active ghrelin receptor agonist that mimics growth hormone secretagogues without injections. Technically a small molecule, but included because it dominates GH-secretagogue conversations alongside CJC-1295/ipamorelin.
MK-677 binds the ghrelin receptor (GHSR-1a), triggering GH and IGF-1 elevation. Unlike peptide secretagogues, it's orally bioavailable.
Studied for
01Sustained GH and IGF-1 elevation
02Improved sleep quality (Stage 3/4)
03Lean mass gain
04No injections required
