Proof Analytical issues instrument-backed, QR-verifiable Certificates of Analysis for the research-peptide and nutraceutical market — so a buyer can confirm identity, purity, and safety instead of taking a supplier's word for it.
A Certificate of Analysis is just a document — and a document can be edited in minutes. A purity number changed, a lot swapped, a cleaner competitor's CoA reused. As demand climbs and the market moves toward regulation, "trust me" stops being good enough. Independent, instrument-backed verification becomes the standard.
A complete Certificate of Analysis covers what a buyer actually needs to trust a research compound — identity, purity, content, safety. Each result is tied to a documented, instrument-based method.
Confirms the compound is what the label says — the correct molecule, verified against a certified reference standard by mass.
LC-MS/MSMeasures how much of the sample is the target compound versus impurities and related substances, reported by chromatographic area.
HPLC-DADQuantifies how much active compound is actually present against the label claim — is the vial full-strength, under-, or over-filled?
HPLC-DADScreens for endotoxin contamination (LAL) — a core safety check for anything intended for injectable research handling.
Endosafe · USP <85>Detects trace toxic elements — lead, arsenic, cadmium, mercury — to compendial limits, so contamination doesn't slip through.
ICP-MS · USP <232>/<233>We run the complete five-test CoA, or individual tests to fit your compound and budget.
Request a quoteSend us your compound and lot details, or request a quote first. We handle chain-of-custody and lot tracking from the moment it arrives.
Your sample is run against documented methods through our accredited partner labs, with reference standards and QC controls on every result — brought in-house as our own lab comes online.
You get a Certificate of Analysis with a unique QR code. Anyone can scan it and confirm the results against our server — the record, not just the paper.
Every Proof Analytical certificate carries a unique verification ID. Enter it below to confirm the certificate is real, issued by us, and unaltered. If the record doesn't appear — or doesn't match the document in your hand — treat it as unverified.

Verification confirms that Proof Analytical issued this certificate record for the identified lot. It does not, by itself, prove that the physical unit in hand is the one tested — that is a question of chain of custody. This lookup is an illustrative preview; the live service runs at verify.proofanalytical.com.
Not a peptide seller with a lab on the side — an independent testing service whose only product is credible, verifiable proof.
Domestic testing with no stake in what we're testing — the independence that makes a certificate mean something.
Domestic logistics and a lean workflow built to return certificates in days, not the weeks an overseas send-out costs you.
Every certificate resolves to a server record via QR. The paper is a rendering of the truth, not the truth itself.
Research-use-only framing, documented methods, reference standards, and ISO 17025 accreditation in progress.
Proof Analytical is an independent analytical testing laboratory serving the research-peptide and nutraceutical market. We exist to do one thing well: turn "trust our supplier" into "verify it yourself."
We issue Certificates of Analysis — identity, purity, assay, endotoxin, and heavy metals — backed by documented, instrument-based methods and certified reference standards, and made independently verifiable through a QR-linked record.
During our buildout, testing is performed by our accredited laboratory partners, and we bring capabilities in-house as our own lab comes online — and we are honest about that: a test is only ever reported from where it was actually run. All compounds are handled and reported for laboratory research use only.
