Overview
MK-677 (ibutamoren) is a non-peptide spiropiperidine that acts as a potent, selective agonist of the ghrelin receptor (GHSR-1a). In research models it functions as a growth-hormone secretagogue, promoting release of growth hormone and IGF-1. Being a small molecule rather than a peptide, it differs structurally from peptidic secretagogues such as ipamorelin or GHRP-6.

FAQ
Pepti supplies MK-677 (ibutamoren) as a research-use reference material in 5mg vials. It is a small-molecule ghrelin-receptor agonist rather than a lyophilized peptide. Alternative fill weights, bulk powder, and custom vialing are available on request for qualifying B2B accounts.
Every batch is supplied with a Certificate of Analysis reporting HPLC purity and identity confirmation by mass spectrometry (MS). Additional documentation such as residual-solvent, appearance, and third-party verification can be provided on request.
Research-grade MK-677 is typically produced to ≥99% by HPLC, with the exact figure stated on the per-batch COA. Purity specifications can be aligned to buyer requirements under an OEM or private-label agreement.
Yes. Pepti is a China-based manufacturer offering private-label and OEM fulfillment, including custom labeling, vial sizes, and packaging. MOQ is confirmed on request based on format and specification.
No. All material is supplied strictly for laboratory research and analytical or manufacturing use. Pepti does not provide medical, dosing, or use guidance, and buyers are responsible for compliance with applicable regulations in their jurisdiction.
