MK-677 benefits
From the PeptideBase research library. Educational only — not medical advice.
Studied effects
- oral GH and IGF-1 stimulation without injection
- fat-free mass increase documented in RCTs
- appetite stimulation via ghrelin receptor agonism
- sustained IGF-1 elevation — long-duration monitoring relevant
Mechanism
MK-677 mimics the action of ghrelin by binding to and activating the GHSR-1a receptor in the pituitary gland, stimulating pulsatile GH release. Its oral bioavailability distinguishes it from peptide-based GH secretagogues and its prolonged half-life results in sustained IGF-1 elevation. Research protocols have explored its effects on lean body mass, bone mineral density, and sleep architecture.
