Batch COA reports

Arctic Lab Supply publishes third-party analytical reports per exact product, strength, and lot. Match the product, strength, and lot to the vial label before relying on a reported result. Each report links to the testing laboratory's verification page.

Currently published reports (7)

Lot-matched reports are published for 7 products. Each product page says whether one exists for that listing.

What the reports contain: every current ILS Laboratories report states chromatographic purity (HPLC), identity by HPLC retention-time match against a reference standard, net peptide content and a fentanyl screen. Four of the seven (BPC-157 5mg, GHK-Cu 50mg, Retatrutide 10mg and 20mg) also include an ICP-MS heavy-metals panel. None includes mass-spectrometry identity testing. The full panel for each lot is on its PDF.

Earlier lots (4)

These February 2026 reports describe earlier lots only, not the lots listed above.

How to verify a report with the issuing laboratory

1. Open the lot's report page or PDF. Note the product, strength, lot number, test date and certificate number (for example COA-2026-Q53ZYU).
2. Follow the laboratory verification link. It opens the issuing laboratory's own portal (portal.ils-lab.com), not a page on this site, which is what makes the check independent of us.
3. Compare the two. The portal record should show the same product, lot, test date and result as the PDF. If anything differs, do not rely on the report and contact support.
4. Match the lot to the label. A report describes one sample from one lot. If the lot printed on a vial is not the lot on the report, the report does not describe that vial.

A step-by-step walkthrough is in how to verify a certificate of analysis, and every field on a report is explained in how to read a certificate of analysis.

Products without a currently published report are listed in the research materials catalog with their documentation status. See the research standards and traceability pages for how records are matched to supplied material.

Questions about these reports

Which products have a published lab report?

Lot-matched reports are currently published for 7 products, listed in the table on this page. Each product page states its documentation status, and a report covers one product, strength and lot only.

Which laboratory issued the reports?

ILS Laboratories issued the current lot reports, and each links to its record on the laboratory's own portal (portal.ils-lab.com). The four earlier reports from February 2026, listed separately under earlier lots, were issued by Janoshik Analytical and link to verify.janoshik.com.

What do the reports test?

The current ILS reports state purity by HPLC, identity by HPLC retention-time match against a reference standard, net peptide content and a fentanyl screen; four of the seven also include an ICP-MS heavy-metals panel. None includes mass-spectrometry identity testing.

How do I check that a report is genuine?

Follow the report's laboratory verification link and compare the product, lot, test date and result on the laboratory's record with the PDF. The laboratory portals render in a normal web browser and may block automated tools. If anything differs, do not rely on the report and contact support.
