Frequently Asked Questions
Everything you need to know about peptide research
All of our peptides maintain 99%+ identity purity, verified through independent third-party HPLC testing. Every batch comes with a Certificate of Analysis (CoA) that you can review before or after purchase.
A CoA is an official document from an accredited laboratory that verifies the identity, purity, and composition of a peptide batch. It typically includes HPLC results, mass spectrometry data, and other analytical measurements.
Amino H2O is our premium bacteriostatic water designed specifically for reconstituting lyophilized peptides in a research setting.
Lyophilized peptides should be stored in a cool, dry place. For long-term storage, we recommend refrigeration at 2-8°C or freezing at -20°C.
When properly stored, lyophilized peptides are typically stable for 12-24 months. Once reconstituted, the solution should be used within a shorter timeframe.
We ship orders within 1 business day. Lyophilized peptides are stable at room temperature for transit. Cold shipping is available upon request for reconstituted products.
Peptide is a U.S.-based research peptide supplier committed to documented quality. Every batch is third-party tested and comes with a Certificate of Analysis.
No. Our products are sold strictly for in vitro research and laboratory use only. They are not intended for human or veterinary use.
Due to the nature of research-grade biochemicals, returns cannot be accepted once shipped to preserve chain-of-custody. However, every order is backed by full shipment protection for damaged or lost packages.
You can reach us through our Contact page, by email at support@peptide.com, or through the live chat feature on our website. We typically respond within 24 hours.
