Knowledge base
View all →Frequently asked questions
All questions → What is an HPLC certificate and what does ≥99% purity mean?
HPLC (High-Performance Liquid Chromatography) is a laboratory method for determining chemical compound purity. Purity ≥99% means the main substance constitutes at least 99% of sample mass, with impurities below 10 mg/g. Every peptiq certificate is issued by an independent laboratory accredited under PN-EN ISO/IEC 17025.
How should peptides be stored in a laboratory?
Store lyophilized peptides at −20°C or below, protected from light and moisture. After reconstitution: 2–8°C, maximum 30 days. Avoid repeated freeze-thaw cycles — divide into single-use aliquots. Lyophilizate stability confirmed by HPLC: up to 24 months.
Are peptiq products drugs or dietary supplements?
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. Not intended for human or animal consumption.
How can I verify the purity of a peptide I ordered?
Every peptiq product has a public certificate of analysis (COA) accessible directly on the product page — not only on request. The certificate includes batch number, HPLC purity percentage, analysis method, and testing laboratory name. You can also commission independent re-analysis at any accredited laboratory.
What payment methods do you accept and how does shipping work?
We accept BLIK, Przelewy24, payment cards (Visa, Mastercard), Apple Pay, and Google Pay. Orders ship within 24 hours (business days) via InPost parcel lockers or courier. Packages include temperature-controlled packing. Consumers have a 14-day right of withdrawal.
What makes peptiq different from other peptide suppliers in Poland?
Three key differences: (1) HPLC analysis performed at an external ISO 17025 accredited laboratory, not in-house — no conflict of interest; (2) COA certificates publicly available on every product page, not only on request; (3) full batch traceability with CAS number, molecular formula, and storage protocol.
