Verify what is in your vial
Every batch we ship is analysed by an independent laboratory and the certificate is published here. Enter the batch number from your vial to retrieve it.
Batch lookup is wired to the COA database in Phase 1. The full published index is available now.
What verification means here
Independent analysis
HPLC purity and mass spectrometry identity confirmation performed by a named third-party laboratory — not in-house, and not described vaguely.
Published per batch
Every lot has its certificate on this site, tied to the batch number printed on the vial. Nothing held back pending request.
Full specifications
CAS number, molecular formula, molecular weight, and sequence published on every product page — the fields that let you check our work independently.
Stated evidence quality
Our research library says plainly where the published literature is thin, single-sourced, or contested. Including when that is inconvenient for us.

Questions
How do I verify the peptide I received?
Every vial carries a batch number on its label. Enter that number here to retrieve the independent certificate of analysis for that specific lot — HPLC purity, mass spectrometry identity confirmation, the testing laboratory, and the date of analysis. If the batch on your vial does not match the certificate, contact us immediately.
Who performs the testing?
Testing is performed by an independent third-party analytical laboratory, named on each certificate. We publish the laboratory rather than describing it generically, because "third-party tested" with no laboratory named is not a verifiable claim.
Why publish certificates instead of providing them on request?
Because 'available on request' is unverifiable before purchase, which is exactly when the information matters. Publishing every certificate means the claim can be checked by anyone, including people who have not bought anything.
What if the molecular weight on the certificate looks wrong?
Check it against published values for that compound, and contact us. This genuinely matters — some compounds are sold industry-wide under names that map to more than one molecule, TB-500 being the clearest example. The certificate is the authoritative statement of what is in the vial.
