# Peptides with a COA in Australia: Reading Lab Reports and HPLC Results Updated 2026-11-10. A certificate of analysis (COA) is a lab report on one sample of a peptide. It names the tests that were run and what each one found. To use a COA, check that the sample lot on the report matches the lot number on your vial. Then read which tests the report covers. This page explains the common tests and then says what the Form Laboratories COA page shows today. | | | | --- | --- | | What a COA is | A lab report on one sample, with the tests it ran | | Common tests | HPLC purity, mass spec identity, heavy metals and endotoxin | | Match to check | The sample lot on the report and the lot number on your vial | | Form Laboratories COA page | Each product's current lot, the sample lot and amount, and the report type on file | | Form Laboratories | Online only, dispatched from Perth, Western Australia | A COA is useful only if you can read it and match it to your vial.

A peptide certificate of analysis shows the result of each test a lab ran on one sample. HPLC purity separates the sample into its parts and reports the main peak's share of all the peaks the method detects. That is not the same as how much peptide is in the vial by weight. Mass spec identity measures the mass of the molecule to show what it is. Heavy metals analysis screens for metals such as lead. Endotoxin testing looks for fragments of bacteria. Each test answers one question. A purity result does not show identity, and an identity result does not show purity. A heavy metals report shows neither. Read [how HPLC purity is measured for peptides](/learn/peptide-quality-verification/how-hplc-purity-is-measured-for-peptides) and [endotoxin, sterility and purity](/learn/peptide-quality-verification/endotoxin-sterility-and-purity) for more on these tests. ## How do I read a certificate of analysis? Check five things on the report: the lot number, the sample amount, the test date, the lab name and the test method. The lot number tells you which material was tested. The method tells you what the result means. A report with no method tells you very little. Look for a result next to each test. Check that the lab name and test date are on the report. For a guide to spotting a real report, read [how to check a peptide COA is genuine](/learn/peptide-quality-verification/how-to-check-a-peptide-coa-is-genuine). ## What does the Form Laboratories COA page show today? The [certificate library](/coa) lists each product's current lot. Next to it, the page shows the sample lot, the sample amount and the type of report on file. Several of the reports on file are heavy metals analysis. Some products have a peptide vial assessment. Some have no sample report on file, and the page says so. A heavy metals analysis does not measure peptide purity or confirm identity. We give no purity figure that is not on a report. We do not claim third-party testing for each lot we sell. The page lists only what is on file. ## How do I match a report to my vial? Find the lot number on your vial label. Then find the sample lot on the report. If the two match, the report is for that material. If they differ, the report says nothing about your vial. Keep the lot number from your label with your records. You can then check it against the [certificate library](/coa) at any time. ## Does a report for an earlier sample lot cover my lot? No. A report for an earlier sample lot does not cover the current lot. A report applies only to the sample, the lot and the tests it names. The COA page shows the sample lot next to the current lot so you can see the difference.

The Form Laboratories COA page lists each product's current lot and the lab report on file. The page shows the type of report and the sample lot. It says when no sample report is on file. Match the lot on your vial to the sample lot on the report. All material is for laboratory research use only. ### What is HPLC testing? HPLC is a lab method that separates a sample into its parts. The purity result is the main peak's share of all the peaks detected under the stated method. It is not the peptide content by weight. We do not say that a product has an HPLC result unless its report on file shows one. ### Is HPLC the same as purity? No. HPLC is the method, and purity is one result it can give. Mass spec checks identity, which is a different question. A report should name each method it used and the result it found. ### How do I match a COA to my vial? Compare the lot number on your vial label with the sample lot on the report. They must be the same. A report for another lot does not cover your vial. ### Where are your reports? They are on the [certificate library](/coa). Each product row has its current lot and, where one exists, a link to the report image. Open the report to read its test, sample lot and sample amount.
