Lab Reports
Each TrueBond lot’s Certificate of Analysis from an independent U.S. laboratory is published here under the lot code printed on the vial. A COA verifies three things: identity (mass spectrometry confirms the molecule is the compound on the label), purity (HPLC quantifies the fraction that is the target compound), and potency (net compound content per vial). Find your lot code below.

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 compound 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 compound. A purity of 99.5% means 99.5% of the compound content is the intended compound; the remainder is typically minor synthesis-related impurities, which the chromatogram shows individually.
Lyophilized compounds contain residual water and counter-ions, so a "10mg" vial is defined by its net compound mass, not gross fill weight. The COA's net content figure tells you exactly how many milligrams of actual compound the tested lot delivers per vial.
What “third-party tested compounds” means here
The phrase is used loosely across this market, so here is our definition, stated checkably. 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 both measurements that matter: HPLC purity and mass-spectrometry identity, because a sample can be highly pure and still be the wrong molecule. And every lot means exactly that. Testing is a requirement per lot, not a sampling schedule, and each certificate is published on this page under the lot code on the vial.
None of it requires trusting us. The lot code on your vial either resolves to a published certificate above, or it does not. That is the difference between a supplier that claims testing and one that can be audited by anyone.
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. Each lot is sent to an independent laboratory for HPLC purity analysis and mass-spectrometry identity confirmation, and its certificate is published here under the lot code as soon as the results are in.
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 lot code on my vial connect to this page?+
Each vial label carries its lot code. Enter it in the search on this page, or open the certificate link from the product page, to reach the report for the exact lot in your hand: its purity, identity confirmation, net content, test date, and dates of manufacture and expiry.
Tested. Published. Verifiable.
Every product in the catalog carries a lot code that maps to this page: independent lab, published numbers, lot-coded vials. Buy against evidence, not claims.
