This checklist is about paperwork, not use. It does not tell you what to do with any compound. If a vendor can't produce a document, write "not on file" — that's a result too.
| # | Document | What it proves | What it does not prove | Where to find it |
|---|---|---|---|---|
| 1 | Lot ID | Which batch you have. Links the vial to a specific test. | Anything about quality by itself. | On the vial label, on the product listing, on the certificate. All three must be the same string. |
| 2 | Certificate of Analysis (COA) | What the lab measured for that lot: identity, purity, sometimes contamination. | That the PDF is real. That it applies to any other lot. | Product page, usually a "View COA" link per lot. |
| 3 | Lab lookup match | The certificate exists in the lab's own database and matches the vendor's PDF. This is what makes #2 real. | — | The lab's public lookup page. Enter the search code from the certificate. |
| 4 | Identity confirmed | The molecule in the vial is the one on the label (LC-MS or equivalent). | Purity, safety, or effect. | The "Identity" line on the certificate. Matters most for names that mean two things (e.g. "TB-500"). |
| 5 | Purity + method + net content | How much of the powder is the named molecule, by which method, and how much was in the vial. | A product-level number. Purity is per lot. A listing's "≥99%" is a claim, not a measurement. | Certificate. For blends, one number per component or the ratio is unverified. |
| 6 | Who you're dealing with + regulator status, dated | The legal entity (state registry), and the compound's FDA / WADA status on the day you checked. | That the vendor is good. That the status won't change. | State business registry · FDA 503A bulk-substances page · WADA Prohibited List. |
If the lookup returns nothing: don't "fix" the code. Don't cite numbers from that file. Mark it unverified and ask the vendor. Worked example: how to read a peptide COA.
"Pharmaceutical grade" · "clinically aligned" · "99%+ purity" on a listing (not a lot) · "USA-made" with no document · "third-party tested" with no lookup · any page that tells you what a research compound will do for you.
