What does “research use only” mean?
Every Peptiva Research Labs product is sold strictly for laboratory and in-vitro research by qualified professionals. Our compounds are not drugs, supplements, or cosmetics and are not for human or veterinary use, consumption, or diagnostic/therapeutic application.
Are your peptides for human use?
No. They are research-grade reference compounds for controlled laboratory study only. By ordering you confirm you are a qualified researcher or authorized laboratory.
How is purity verified?
Each batch is analyzed by reverse-phase HPLC-UV for chromatographic purity (≥ 99% target) and by LC-MS for identity, and is screened for bacterial endotoxins by the LAL method.
Do you provide a Certificate of Analysis?
How should peptides be stored and reconstituted?
Lyophilized peptide is typically kept desiccated and frozen (-20°C) away from light. For experimental use it is commonly reconstituted with bacteriostatic or sterile water, then aliquoted to limit freeze-thaw cycles. Follow your laboratory's protocols.
