Peptides are short chains of amino acids. The products we supply are synthetic peptides manufactured as reference materials for in-vitro laboratory research — studying biological pathways, assay development, and experimental work. They are reagents, not medicines.

No. All products are sold strictly for laboratory research use only and are not for human or animal consumption, injection, or any form of administration. They are not approved by the HSA as health or therapeutic products. See our Research-Use-Only Disclaimer.

Purity is >99% (manufacturer’s HPLC specification). Batch documentation is available on request — message @north_vial before you order. Products are supplied as lyophilised powder in sealed vials.

Products ship as lyophilised (freeze-dried) powder in sealed vials. Store lyophilised vials at 2–8 °C, protected from direct sunlight (−20 °C for long-term storage). Once reconstituted for research handling, keep refrigerated and use within the period appropriate to the peptide. Proper storage after delivery is the buyer’s responsibility.

Bacteriostatic water (0.9% benzyl alcohol) is a reconstitution diluent used to dissolve lyophilised peptides for laboratory handling. We stock it under Supplies.
