Third-party laboratory Certificates of Analysis (COA) for every PEPTEX peptide
Research-grade peptides require verified identity and purity. An unverified vial is an unverified experiment.
Each order ships with a physical COA and batch-specific QR code.
HPLC (purity + impurities), mass spectrometry (molecular mass confirmation), appearance check, and moisture content. Reports issued by EU-based accredited laboratories.
Every batch of PEPTEX peptides is tested by an independent accredited laboratory. All batches meet or exceed ≥99% purity — no exceptions.
It means that at least 99% of the powder is the target peptide.
Every vial carries a batch number matching the COA.
Yes — each COA carries the issuing laboratory name and report ID.
