Frequently asked questions
Answers about research peptide reagents, HPLC certificates, payments, and shipping.
What is an HPLC certificate?
HPLC (High-Performance Liquid Chromatography) is a laboratory method for analyzing chemical compound purity. An HPLC certificate confirms the percentage of active substance in a given batch. Every peptiq certificate is issued by an independent laboratory accredited under PN-EN ISO/IEC 17025.
Are peptiq products drugs?
No. peptiq products are chemical reagents intended exclusively for in vitro laboratory research. They are not medicinal products, dietary supplements, cosmetics, or medical devices under applicable regulations. They are not intended for human or animal consumption.
How should peptides be stored?
Lyophilized peptides should be stored at −20°C or below, protected from light and moisture. After reconstitution, store at 2–8°C, protected from light, for a maximum of 30 days. Avoid repeated freeze-thaw cycles.
