MK-677 (ibutamoren) is an orally active growth hormone secretagogue (ghrelin receptor agonist). Investigational; not FDA-approved. Taken orally.
Mechanism
MK-677 (ibutamoren) is an orally active, non-peptide ghrelin receptor (GHS-R1a) agonist that stimulates growth-hormone and IGF-1 secretion. Unlike peptide secretagogues, it is absorbed orally.
Research summary
Studied in clinical trials as a growth-hormone secretagogue, including in older adults and in the context of body composition. It is not FDA-approved, and long-term outcome data are limited.
Reported side effects
Reported effects include increased appetite, water retention, transient increases in blood glucose and insulin resistance, and fatigue. Effects on growth hormone and IGF-1 warrant monitoring. The full profile is not established.
