MK-677: USA-Made Research Peptide

Manufactured & Packaged in the USA

Our MK-677 is manufactured, lyophilized and packaged in the USA — no overseas manufacturing, no imports. From peptide manufacturing to lyophilization and vial filling, every step happens on U.S. soil — we never re-label imported material. This gives researchers a transparent, fully domestic chain of custody from raw amino acids to the sealed vial on your bench.

Because production is domestic, batch records, testing data and reship windows are all handled in-house, which shortens lead times and removes the customs delays and quality uncertainty that come with overseas peptide sourcing.

Third-Party Purity & COAs for MK-677

Independent ISO 17025 lab testing confirms ≥99% purity on every lot, with HPLC and mass-spec COAs available.

A representative COA is available on request for each MK-677 lot, documenting identity, net peptide content and mass. This is the same documentation clinics, compounding partners and research labs expect before qualifying a supplier.

Research Context

As a oral gh secretagogue, MK-677 is studied for sustained growth-hormone and IGF-1 elevation through ghrelin-receptor activation. All PX1 material is sold strictly for laboratory and research use only — not for human or veterinary use.

Wholesale & Bulk MK-677

MK-677 is available at wholesale pricing for clinics, telehealth platforms, med spas and research groups. Bulk orders can be custom-labeled with your brand, and every SKU can ship with a branded COA. Minimum wholesale order is 100 vials per SKU.
