Why the lookup matters
Anyone can edit a PDF. A report you open on the laboratory’s own website, using a code printed on the report, is the only version the seller can’t change. If the lab’s copy matches the seller’s copy and the lot number matches your vial, the report describes what you have. If any of those three don’t line up, it doesn’t.
The three-way match
- Seller’s copy. Find the report on the product page or the seller’s report library. Note the lab name, the report or certificate number, the product, the labeled amount and the lot number.
- Lab’s copy. Open the lab’s verification page yourself (type the lab’s address, don’t trust a link that only leads to the seller’s domain) and look the report up. Product, amount, lot, results and dates should be identical.
- Your vial. When the parcel arrives, the lot number on the label should be the lot number on the report.
Janoshik
Janoshik reports carry a task number and a unique key. The public verification page uses both, in the form verify.janoshik.com/tests/<task number>_<key>. Open it and compare the sample description and results with the seller’s copy. Janoshik’s pages render in a normal browser and may block automated tools, so check by hand.
Arctic used Janoshik on earlier lots. Those reports stay listed with their verification links for reference.
Freedom Diagnostics
Freedom Diagnostics reports carry a unique accession number. Their site has a search page for it: go to freedomdiagnosticstesting.com, open “Search for your COA based on the unique accession number” and enter the lookup code printed on the report. Arctic’s codes look like Arct2610140675.
Arctic’s Freedom Diagnostics reports from October 2026 cover identity by LC-MS (mass spectrometry), purity by HPLC-UV and an endotoxin test. See the Tesamorelin 10MG lot TS-2502B report for a live example.
ILS Laboratories
ILS reports carry a certificate number such as COA-2026-Q53ZYU and a verification link on the ILS portal in the form portal.ils-lab.com/verify/<code>. Open it and compare it with the PDF. See the BPC-157 5MG lot BCP-2502-B report for a live example.
Red flags
- The “verification” link opens a page on the seller’s own domain.
- A screenshot or image instead of a report you can look up.
- No lot number, or a lot number that never appears on the vial label.
- The same report reused across strengths or products.
- A report dated long before the lot could have been made, or with no test date at all.
- The lab’s copy differs from the seller’s copy in any number.
Check ours yourself. Every current report is public, with the lot number and a link to the lab’s own verification page.
Questions
How do I verify a Janoshik report?
Use the task number and key printed on the report. Janoshik's public verification page has the form verify.janoshik.com/tests/<task number>_<key>. Compare the sample description, lot and results with the seller's copy.
How do I verify a Freedom Diagnostics report?
Go to freedomdiagnosticstesting.com, open the page to search for your COA by unique accession number, and enter the lookup code printed on the report. The lab's copy should match the seller's copy exactly.
How do I verify an ILS Laboratories report?
ILS reports link to a verification page on the ILS portal (portal.ils-lab.com/verify/...). Open it from the report and check that the product, amount, lot and results match.
What if the lot number on my vial doesn't match the report?
Then the report doesn't describe your vial. Ask the seller for the report for the lot you received, and check that one on the lab's site the same way.
Does Arctic publish reports for every product?
No. Arctic publishes a report for each lot it has had independently tested, and each product page says whether a lot-matched report is currently published. The current reports are listed at arcticlabsupply.com/coas.
