Lab Reports
Certificates of Analysis from an independent U.S. laboratory, published in full under the lot code printed on the vial. Each reports identity (whether the material is the peptide on the label) and purity (the HPLC share that is the target compound), for the lot printed on the vial. Find your lot code below.
Check your vial. Search the lot code on its label below to find that lot’s certificate, once it’s published.

How to read a COA
Three things on every certificate tell you what the tested lot is and how pure it tested.
The identity result says whether the laboratory confirmed the material in the vial is the peptide named on the label, rather than a different compound or a mislabeled product. Every certificate on this page reports it.
HPLC separates the sample into its components and reports what share of the detected material is the target peptide. A purity of 99.5% means the target makes up 99.5% of what the run detected; the rest is typically minor synthesis-related impurities, which the chromatogram shows as separate peaks.
Every certificate names the lot it tested. That lot number is the code on your vial's label, so if your vial's lot has a published certificate, this is where you find it.
What “third-party tested peptides” means here
Here is what the phrase means on this site, stated so you can check it. Third-party means the laboratory is independent: it has no stake in the result, runs its own calibrated instruments, and issues a document we cannot quietly edit. Tested means the measurements that matter: HPLC purity and identity, because a sample can be highly pure and still be the wrong molecule. And published means in full: each certificate is posted on this page exactly as the laboratory issued it, under its lot code.
None of it requires trusting us. Search the lot code on your vial above: if its certificate is published, it opens here.
Testing FAQ
How the testing program works, and what it means for the vial in your hand.
Why does third-party testing matter?+
In-house testing is a claim; independent testing is evidence. A third-party laboratory has no stake in the result, uses its own calibrated instruments, and issues a document the supplier cannot quietly edit. Publishing those certificates lot by lot means the numbers can be checked against an outside source rather than taken on trust.
Which lab tests TrueBond lots?+
The certificates on this page were issued by an independent third-party lab. Each one reports HPLC purity and an identity result, and each is posted here in full under its lot code.
How does the lot code on my vial connect to this page?+
Each vial label carries its lot code. Enter it in the search on this page to find that lot's certificate, if it's published: its purity, identity result, the laboratory, the test dates and the full certificate. If it isn't listed yet, email support@truebondlabs.com.
