Answers about quality, lab standards, and research use — all in one place.
No. Norvik Peptides is an informational resource on peptides for laboratory and research purposes. Products are not for human or veterinary consumption, diagnosis, or treatment.
Each COA includes the batch number, HPLC test date, and purity results. Compare the batch number on your vial label with the document. You can read more about COA certificates in our journal.
Every lot undergoes HPLC analysis against reference standards. We publish ≥99% results transparently, and an independent laboratory additionally verifies molecular identity before shipment.
Peptides ship in insulated containers with gel packs and tracked courier delivery. We recommend storing product at −20 °C immediately upon receipt, or as directed on the COA.
Store lyophilized vials at −20 °C, protected from light and moisture. After reconstitution with bacteriostatic water, keep at 2–8 °C and use within the window listed in the product specification (typically 5–7 days).
