Lab Reports
Every TrueBond lot ships with a Certificate of Analysis from an independent U.S. laboratory. A COA verifies three things: identity (mass spectrometry confirms the molecule is the peptide on the label), purity (HPLC quantifies the fraction that is the target compound), and potency (net peptide content per vial). Find your lot below or scan the QR code on your vial.

How to read a COA
Three numbers on every certificate tell you whether a vial is what it claims to be.
Mass spectrometry measures the exact molecular weight of the compound in the vial and compares it against the known reference mass for that peptide sequence. A match confirms the material is what the label says it is — not a different compound, a truncated sequence, or a mislabeled product.
HPLC separates everything in the sample and reports what fraction of the total is the target peptide. A purity of 99.5% means 99.5% of the peptide content is the intended compound; the remainder is typically minor synthesis-related impurities, which the chromatogram shows individually.
Lyophilized peptides contain residual water and counter-ions, so a "10mg" vial is defined by its net peptide mass, not gross fill weight. The COA's net content figure tells you exactly how many milligrams of actual peptide the tested lot delivers per vial.
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 results lot by lot means every claim on our labels can be checked against an outside source rather than taken on trust.
How often are lots tested?+
Every lot, without exception. No lot enters inventory until an independent laboratory has completed HPLC purity analysis and mass-spectrometry identity confirmation and the results are published on this page. There is no sampling schedule or spot-checking — testing is a release requirement for each individual lot.
What happens if a lot fails testing?+
It never reaches this page — or your hands. A lot that misses its identity match, purity specification, or net content tolerance is rejected and destroyed rather than discounted or blended away. The lots listed above are the ones that passed; there is no separate tier of unpublished inventory.
How does the QR code on my vial connect to this page?+
Each vial label carries a QR code encoding the URL of that lot's dedicated report page on this site. Scanning it takes you straight to the certificate for the exact lot in your hand — its purity, identity confirmation, net content, test date, and dates of manufacture and expiry — with no searching required.
Tested. Published. Verifiable.
Every product in the catalog traces back to a lot on this page — independent lab, published numbers, QR-coded vials. Buy against evidence, not claims.
