Verify a Certificate of Analysis.
Enter the lot number from your vial, or scan the QR code on the label. We'll pull up that lot's full Certificate of Analysis from the independent testing laboratory.
Three steps to verify any lot.
Every vial we ship has a unique identifier linking to its specific Certificate of Analysis, hosted independently by the testing laboratory. Verification takes seconds.
Locate Your Lot Number
Find the unique lot number printed on your vial label. It begins with USCP followed by the year and a four-digit identifier.
Enter or Scan
Type the lot number into the verification field above, or scan the QR code on your vial with any phone camera.
View the Certificate
You'll be taken directly to the laboratory-hosted Certificate of Analysis for that specific lot. Review test results, methods, and signatures.
The COA you see is hosted by the testing laboratory, not by us.
We cannot edit, modify, or alter any COA. What you see is what the lab issued.
A real verification, in real time.
This is what a successful verification looks like. The actual COA appears in a clean preview with all seven test results, methods, and pass/fail status visible at a glance.
Elite Certification Test Results
Verified Status
A green verified badge confirms the lot exists in the laboratory's database and has passed all seven tests.
Full Test Data
Every test displays its method, exact result, and pass/fail status. Nothing is hidden or summarized.
Downloadable PDF
The complete signed COA can be downloaded directly from the verification page for your records.
If Verification Fails
If your lot number does not return a valid COA, the product may be counterfeit, mislabeled, or not from US Certified Peptides. Contact us immediately at support@uscertifiedpeptides.com so we can investigate.
Why this verification matters.
In a market full of unverified peptides, third-party hosted COAs are the only meaningful proof of what's in the vial. Here's how our verification system protects researchers.
Third-Party Hosted
Every COA lives on the testing laboratory's servers, not ours. We cannot edit, modify, or delete any certificate. The data you see is the data the lab issued.
Unique Lot Tracking
Each vial carries a one-time identifier linking to one specific COA. No two lots share an identifier. No identifier appears on more than one vial.
Secure QR Links
QR codes link directly to laboratory-hosted COAs via encrypted connections. The path between vial and certificate is tamper-evident.
Independent Accreditation
The testing laboratory holds ISO/IEC 17025:2017 accreditation, independently audited. The accreditation is publicly verifiable through international accreditation bodies.
The system is designed so we cannot lie.
Even if we wanted to.
Questions about verification.
Common questions about the verification process, lot numbers, and what to do if something doesn't match.
The lot number is printed on the white wraparound label of every vial, typically near the bottom of the label or adjacent to the ELITE CERTIFIED seal. It begins with USCP followed by the four-digit year and a four-digit identifier (example: USCP-2026-0142).
If the lot number returns no result, double-check the format and spelling. Lot numbers are case-sensitive and include the hyphens. If the format is correct and verification still fails, the product may be counterfeit, mislabeled, or not from US Certified Peptides. Contact support@uscertifiedpeptides.com immediately so we can investigate.
Yes. The QR code on every vial works with any standard phone camera or QR scanner app. Open your camera, point it at the QR code, and tap the link that appears. You'll be taken directly to the laboratory-hosted COA for that specific lot.
Third-party hosting is fundamental to the integrity of the verification system. If we hosted our own COAs, we could theoretically modify or fabricate them. By hosting on the independent testing laboratory's servers, the data is tamper-evident. We cannot alter what we did not create.
Yes. After verification, a 'Download Full COA (PDF)' button appears on the verification page. The downloaded PDF includes all seven test results, methods, signatures, and the laboratory's official letterhead. Save it for compliance, audit, or grant documentation.
A COA reflects testing performed on a specific lot at a specific date. The certificate itself does not expire, but the peptide's shelf life and storage conditions affect ongoing quality. Refer to the storage and stability guidance on the product page for each peptide.
If the verified COA does not match your vial (different peptide, different dosage, different lot number), do not use the product. Contact us immediately at support@uscertifiedpeptides.com with photos of your vial and label. This is a critical issue requiring immediate investigation.
Lot number lookups are not tied to your account or personal information. The verification system only confirms whether a lot exists and returns its COA. We do not collect verification queries against researcher profiles. Anyone can verify any lot at any time.
