MK-677 (Ibutamoren) 12.5mg 60-Capsule Overview
MK-677 (Ibutamoren) 12.5mg 60-Capsule from Peptide Science is the encapsulated oral-format research preparation of the orally-active small-molecule ghrelin-receptor agonist, supplied at 12.5 milligrams per capsule in a 60-count sealed bottle for preclinical animal-model research on the GH and IGF-1 axis.
Class and Mechanism in Preclinical Research
MK-677 (Ibutamoren mesylate) is a non-peptide small-molecule agonist of the growth-hormone secretagogue receptor (GHS-R1a), distinguished from the peptide GHRP-class compounds by its oral bioavailability and extended plasma half-life. Preclinical research has characterised the compound for sustained activation of the ghrelin-receptor pathway in cell-culture and animal-model studies, with reported downstream effects on growth hormone and IGF-1 axis activity over multi-day administration periods. The compound is sometimes mis-classified as a SARM in lay sources, which is incorrect: MK-677 has no androgen-receptor activity.
