Type the provider, product, or the lot number printed on your vial or COA.
Select the certificate that matches your exact lot.
Each parameter is compared against its spec and flagged PASS or out-of-spec automatically.
Review the issue date and verified status for that exact lot before you trust the material.
A COA is the lab report a manufacturer issues for a specific production lot. It lists each quality test, the specification (the limit the product must meet), and the measured result for that batch. Verifying a COA confirms the peptide is what the label claims, at the purity claimed, for that exact lot. Here's what the key parameters mean:
PeptiScan reads the specification on each row (for example “≥99.0%”, “≤0.5%”, “7.0–8.0”, or “4731.4 ± 1 Da”) and compares it to the measured result. If the result falls inside the allowed limit it shows PASS; if it falls outside it shows OUT OF SPEC. Qualitative rows like solubility are marked REPORTED.
A COA verifies the lab data for a stated lot, not the physical vial in your hand. Always confirm the lot number printed on the vial matches the certificate shown here, along with the issue date.
Yes. PeptiScan can host certificates from any supplier. Add the company and its COA data and it becomes searchable alongside the rest.
Because the powder also contains water and counter-ions. The Net Peptide Content tells you the actual peptide mass — always dose from NPC, not the gross label weight.
