ILS Laboratories: Peptide Panels, Prices and How to Verify an ILS COA

ILS Laboratories is a San Diego testing lab that sells HPLC and full QC panels for research peptides and lets anyone check a report on its own site with a short access code. Its standard panels confirm identity by HPLC retention time rather than mass spectrometry, which is worth knowing when you read one of its certificates. 10 vendors in our directory cite it as of October 21, 2026.

Notice: Research peptides are sold for in-vitro laboratory research only. They are not FDA-approved, not for human or animal consumption, and this page is not medical advice. It contains no dosing or use guidance.

Who runs ILS Laboratories

ILS's about page says it was founded in 2019 and is located at 8222 Vickers St, Suite 106, San Diego, CA 92111, in Kearny Mesa. It names two entities: lab services are provided by ILS Labs Inc., and the platform and billing are run by ILS Analytical LLC. It also tests supplements, cosmetics, raw materials and cannabis.

Our directory files this lab as "ILS Lab." The certificates vendors post, such as this Drexa Labs report, carry the San Diego address and the ils-lab.com domain, so that's the entity this page covers.

Accreditation. ILS says it is "ISO/IEC 17025 accredited for activities within our accredited scope." Its site doesn't name the accrediting body or a certificate number. The Drexa certificate refers to the lab's PJLA scope but gives no number, and we couldn't confirm the listing or its scope in PJLA's directory. ILS also says "Peptide testing is performed for Research Use Only," and doesn't state that peptide tests fall inside the accredited scope.

What it tests and what it costs

ILS's peptide testing page listed these standard new-account prices on October 21, 2026:

Methods, per the same page:

• Purity and quantity: HPLC/UPLC.
• Identity: HPLC retention-time matching against certified reference standards. LC-MS isn't part of the standard panels.
• Endotoxin: kinetic chromogenic LAL per USP <85>, reported in EU/mg.
• Sterility: a DNA microarray rapid screen that returns results in days, not the 14-day culture incubation.
• Heavy metals: ICP-MS per ICH Q3D. The page names copper, zinc, iron and lead among the metals screened but gives no full list.

Standard turnaround is about one week from sample receipt.

How to verify an ILS report

1. Find the access code. ILS's verify page says it's a 7-8 character code "printed in bold directly below the QR code" in the header, and repeated next to "Access Code:" in the footer.
2. Type ils-lab.com yourself and open Verify COA, or scan the QR code and check it opens an ils-lab.com address.
3. Enter the code. The page shows the lab's record: test results, product information and the signatory.
4. Compare line by line with the vendor's PDF: COA number, client, product, lot, dates and every result.
5. Match the lot to your vial.

What an ILS COA does and doesn't prove

The Drexa certificate states that the sample identity, product name and lot number "were supplied by the submitter and not independently verified." That's true of nearly every vendor-commissioned COA, and ILS says so plainly. The $100 additional-brand COA also means one test can appear under more than one brand. Our HPLC purity guide explains retention time and purity, and the endotoxin guide covers EU results.

Vendors in our directory that cite ILS

From our vendor directory data, checked October 19-21, 2026. "Lot numbers shown" means the vendor's COA page shows lot or batch numbers next to its certificates. When we re-checked Peptide Confidential's results page on October 21, 2026, the lots shown there named other labs, so check the certificate for your own lot.

Work through any report with our COA checklist, and see third-party tested peptides for vendors with independent results.
