Answers

Frequently asked questions

Catalog peptides are specified at 99%+ identity purity. Each lot is verified by an independent laboratory using HPLC and mass spectrometry, and the results are published in that lot's Certificate of Analysis.

A COA is the lab document issued for a specific production lot. It records the compound's identity confirmation, measured purity and the lot number, so the vial on the bench can be traced back to its test results.

No. Every product is sold strictly for in-vitro laboratory research. Nothing in the catalog is for human or veterinary use, and no product has been evaluated by the FDA for safety or efficacy.

Orders placed before the daily cutoff ship the same or next business day from a US facility. Lyophilized peptides are stable in transit and do not require cold shipping.

L-H2O is a sterile, USP-grade laboratory solvent containing 0.9% benzyl alcohol. It is a bench accessory, not a peptide, and carries no HPLC purity claim or COA.

Unopened products can be returned within 30 days of delivery. Lost or damaged shipments are covered by the shipment protection included with every order.
