MK-677 (Ibutamoren) 25mg – 60 capsules

MK-677 (Ibutamoren) 25 mg – 60 capsules research-grade capsule formulation supplied in a sealed bottle. MK-677 (also known as Ibutamoren) is a non-peptidic growth hormone secretagogue studied in experimental models of growth hormone/IGF-1 axis modulation, body composition, bone and muscle metabolism and sleep-related neuroendocrine signaling.

Research Overview

MK-677 (Ibutamoren) is a small-molecule, non-peptidic growth hormone secretagogue that acts as an agonist at the ghrelin receptor (GHSR1a). In experimental systems, it is used to probe regulation of the growth hormone/IGF-1 axis, energy balance, body composition, bone remodeling and sleep-related neuroendocrine signaling in both in vitro and in vivo research models.

Primary Research Areas

• Growth hormone / IGF-1 axis modulation: Used in preclinical models to study how ghrelin-receptor agonism influences pituitary growth hormone secretion, circulating IGF-1 and downstream anabolic signaling pathways.
• Body composition and energy balance: Investigated in experimental settings evaluating lean mass, fat mass, nutrient partitioning and metabolic rate under conditions of altered GH/IGF-1 signaling.
• Bone density and musculoskeletal research: Applied in models of bone remodeling and muscle catabolism to explore interactions between GH/IGF-1 signaling, bone mineralization and muscle protein turnover.
• Sleep architecture and neuroendocrine rhythms: Used to examine relationships between ghrelin-receptor activation, slow-wave sleep, circadian hormone release and neuroendocrine homeostasis in experimental systems.
• Appetite and feeding behavior: Employed as a tool compound in studies of appetite regulation, hunger signaling and reward-linked feeding behavior mediated through central ghrelin pathways.
