MK-677, also known as Ibutamoren, is an orally active, non-peptide agonist of the ghrelin receptor (GHSR). Research indicates it promotes the secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1), both of which play key roles in muscle growth, fat metabolism, recovery, and tissue repair. Unlike injectable growth hormone secretagogues, MK-677 is notable for its oral bioavailability and sustained activity, making it a widely studied compound in the field of endocrinology and metabolic research.
Investigations suggest MK-677 may support lean body mass preservation, enhance sleep quality, and improve recovery parameters, with potential applications in sarcopenia, cachexia, and age-related hormone decline.
