Every batch, third-party tested.
Every COA, public.
Since Aug 2025, every Pantheon Peptides batch has been purity-tested by an independent lab, with the certificate published below. Find your vial’s batch number to see its purity and analysis date, or verify directly with the lab.
Verified by three independent labs
We use three unaffiliated labs on purpose because cross-checking results means we’re not locked in with a single provider, and you don’t have to take our word on results.
Specialized peptide analytical lab — every batch we send to Freedom is independently verifiable at freedomdiagnosticstesting.com/search-for-your-coa-based-on-the-unique-accession-number.
Operates a public verify portal — every batch we send to Chromate is independently verifiable at chromate.org/verify.
Toronto-based peptide testing laboratory. Every Testides COA includes a QR code for direct digital verification at testides.com.
What do the lab tests actually prove?â–ľ
Separates the peptide from any contaminants and measures the percentage that’s the active compound. The remainder is residual synthesis byproduct.
Where the lab runs it, mass spectrometry confirms the molecular weight matches the peptide on the label, which catches mislabelled or substituted product. Chromate and Freedom Diagnostics pair it with HPLC; Testides reports HPLC-UV purity and content.
Means the batch met the lab’s pass criteria for identity, quantity, and purity at the specification listed on the certificate. Where a batch falls marginally short, it is reviewed individually and shown as Reviewed & released rather than as conforming.
Why do some peptides have a lower purity threshold?â–ľ
Most batches test above 99% purity. Every batch is released against the third-party specification appropriate to that peptide — greater than 98% for most products, greater than 90% for a few where the analytical method has known limits for that compound. A small number of products, such as Cerebrolysin, are peptide mixtures rather than single defined compounds, and are reviewed against an identity and composition standard instead of a purity percentage.

Batch not on file?
Some older lots may not be published yet. Email us your batch number and we’ll send the certificate directly. If we can’t produce one, we’ll refund the order — full stop.
COA doesn’t match what you received?
Photograph the vial label and send it to support. We’ll investigate the lot and replace the order at our cost while we do.
Every vial, traced.
You can buy peptides from a lot of places. We’re one of the few who’ll show you exactly what’s in the bottle, batch by batch.
