This product is intended for laboratory and research use only. Not for human consumption.

Ibutamoren MK-677 is a potent, orally active ghrelin receptor agonist and growth hormone secretagogue studied in preclinical and clinical research for its ability to stimulate GH and IGF-1 secretion without significantly suppressing endogenous hormone production. Unlike injectable GH secretagogues, MK-677 demonstrates oral bioavailability, making it a convenient tool for long-duration research studies. Research has examined MK-677 for GH axis stimulation, muscle mass, bone mineral density, sleep architecture, and metabolic parameters. PeptideBull supplies Ibutamoren MK-677 at research-grade purity. Not for human or veterinary consumption.
