Overview
About MK-677 (Ibutamoren).
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
MK-677 (Ibutamoren) — frequently asked by B2B buyers.
What form is MK-677 supplied in?
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.
What documentation ships with each batch?
For the applicable lot, Pepti confirms the available document set during RFQ review. Depending on the product and lot, the set can include 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.
What purity does Pepti target for MK-677?
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.
Do you support private-label and OEM orders?
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.
Is MK-677 sold for therapeutic or consumer use?
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.
