Storage & Handling

All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.

  • On arrival: Store vials in a cool, dry place away from heat and direct sunlight.
  • Long-term (powder): For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
  • After reconstitution: Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.

Note: Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.

Peak Lab Peptides maintains quality-control processes and routinely performs third-party testing to support purity and identity verification. COAs are available upon request for applicable batches. Documentation may vary depending on production timelines.

We aim to make batch-level documentation available whenever possible. Our goal is to expand COA access across the full catalog as production capacity grows.
