Peptides are not returnable once dispatched — opened vials cannot be re-qualified. Lots received damaged, mislabelled, or deviating from the certificate are replaced at our expense.
- Report issues within 14 days of delivery.
- One reshipment per 12 months covered for confirmed customs loss.
- Reference samples retained 12 months for dispute re-testing.
- Re-test performed by Janoshik at our cost if independent testing disputes the certificate.
Lyophilised peptides in argon-purged amber glass are stable at ambient temperature for up to 30 days — manufacturer-confirmed for all catalogue peptides. Cold-chain dispatch is therefore not required. On receipt, transfer to −20 °C for long-term storage.
GHK-Cu is an exception only in that it should be kept away from prolonged direct sunlight during transit; the copper complex absorbs in the visible range. Our mailers are opaque; in-transit light exposure is not a material concern.
