What MK-677 is
A non-peptide, orally active ghrelin receptor agonist that raises growth hormone and IGF-1. Completed but did not pass Phase 3 for approval.
MK-677 stimulates pituitary growth hormone secretion by mimicking ghrelin. Unlike injectable secretagogues it is orally active with a long half-life.
Mechanism: Agonizes the ghrelin/GH secretagogue receptor (GHS-R1a), increasing GH and IGF-1 while also stimulating appetite.
Regulatory history: Not FDA-approved (failed to gain approval after Phase 3)

The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for MK-677 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
