Peptide purity, certified and publicly verifiable.
HPLC purity + LC-MS identity on every batch. Each certificate is tamper-evident and verifiable by accession code, brand, or secret key.
How certification works
From sample to a certificate the whole market can independently trust.
Your batch is registered with an accession code and a tamper-evident chain of custody.
Reverse-phase HPLC quantifies purity; LC-MS confirms the molecular identity of the peptide.
Chromatogram, mass spectrum, contaminant panel (water, endotoxin, heavy metals) and a document hash — compiled into one certificate.
Anyone confirms authenticity by accession, brand, or secret key. The hash exposes any altered PDF.
A COA built to be trusted
Generated graphics, real analytical structure, and anti-fraud controls on every page.
