Testing summary
Peptide Hackers publishes 34 Certificates of Analysis from Accumark Labs (Anaheim, California) and Janoshik Analytical (Prague). 29 report HPLC purity, from 98.138% to 99.983%; the other 5 are blends or non-peptide products tested for quantity only. Every certificate links to the lab's own record.
The lowest HPLC purity across our published certificates is currently 98.138%. Blends and a few compounds are reported by quantity only. See each product's certificate on our COA page.

Accumark Labs
24 certificatesAnaheim, California
HPLC purity · Identity · Quantity (mg per vial)
US analytical lab. Each AccuVerify report is rendered directly from the lab's LIMS with a downloadable PDF and a result hash anchored at finalization, so the published numbers cannot be edited or swapped.
Janoshik Analytical
10 certificatesPrague
HPLC purity · Quantity (mg per vial)
Independent peptide testing lab with a public verification database — every report has a unique URL anyone can open to confirm the measured content and purity results.
How to verify a certificate yourself
Open the lab's report
"Full report" opens the testing lab's own page — Janoshik's public database or Accumark's AccuVerify portal — not a file we host.
Match the report ID
Each card shows the report ID the lab printed, where the lab issued one. If it matches the lab's page, you're looking at the same test.
Compare the figures
Purity and quantity on the card are copied exactly from the report. Where several vials were tested, every vial is on the lab's page.
Step by step, with one of our own reports as the example: verify a Janoshik COA · verify an Accumark AccuVerify COA
Red flags on a peptide COA
| Red flag | How ours answer it |
|---|---|
| No way to check it at the lab | A PDF or screenshot alone can be edited. Every certificate here links to the testing lab's own record of the result. |
| Report ID doesn't match the lab's page | Each card shows the report ID the lab printed, where the lab issued one, so you can match it on the lab's page. |
| Figures differ from the lab's report | We copy purity and quantity exactly as reported, including every vial when a lab tested several. |
| The report tests a different compound | Check that the compound on the lab's report is the product you are buying, not a different sample. |
| No named testing lab | Each certificate names the independent lab that issued it, with a link to that lab's website. |
About these certificates
Each Certificate of Analysis documents the analytical testing performed on a specific sample and links to the lab's own report. Where a lab tested several vials, the card shows the lowest purity or the full range, and every vial is on the report.

COA questions
What is a peptide Certificate of Analysis (COA)?
A COA is a lab report on a tested sample. It usually lists the lot number, the methods used (such as HPLC for purity) and the measured results, so you can confirm the compound is what the label says.
How do I verify a COA is real?
Open the lab report link on the certificate page. It goes to the testing lab's own website (for example Janoshik's public verification database or Accumark's AccuVerify portal), not a file we host, so the result cannot be edited by us.
Which labs test Peptide Hackers peptides?
Our current certificates come from Accumark Labs and Janoshik Analytical. Each certificate names the lab that issued it.
What purity should a research peptide have?
HPLC purity of 98% or higher is the usual research-grade threshold. Most of our certificates show HPLC purity for the tested sample. Blends and a few compounds are reported by quantity only, and each certificate shows exactly what its lab measured.
What is the difference between an in-house and a third-party COA?
An in-house COA is produced by the seller or manufacturer. A third-party COA is issued by an independent lab with no stake in the result. Every certificate on this page comes from an independent lab and links to that lab's own record.
Can a COA be faked?
Yes. PDFs and screenshots can be edited or reused. The reliable check is the lab's own verification page: open the lab report link and confirm the report ID and figures match.
What do HPLC and mass spectrometry show on a COA?
HPLC separates the sample and reports purity as the share of the main compound. Mass spectrometry confirms identity by measuring molecular weight. Our current certificates don't state a mass spectrometry method. Accumark reports include an identity result, and Janoshik reports cover purity and quantity. Each certificate lists the tests its lab reported.
Does the COA match the lot I receive?
Where a certificate shows the lab's lot, compare it with the lot printed on your vial label. Otherwise the report ID and product are the reference, and the full lab report has every detail the lab printed.
Do you test for endotoxins?
Endotoxin testing is scheduled. Results will be posted on this page as each one is completed.
