COA documents are available on each individual product page. You can view and download them directly. For specific batch COAs or historical data, contact our support team.

Lyophilized (freeze-dried) peptides should be stored at -20C for long-term storage. Once reconstituted, store at 2-8C (refrigerator) and use within 30 days. Avoid repeated freeze-thaw cycles.

Use bacteriostatic water (BAC water) for reconstitution. Slowly inject the water along the side of the vial, allowing the lyophilized powder to dissolve naturally. Do not shake vigorously. Detailed instructions are included with each product.

Lyophilized peptides stored properly at -20C have a shelf life of 24-36 months from the date of manufacture. Reconstituted peptides should be used within 30 days when refrigerated.

Always wear appropriate PPE including gloves and safety glasses when handling peptides. Work in a clean, sterile environment. These products are for research use only and should only be handled by qualified research professionals.
