What is HPLC purity testing?

High-Performance Liquid Chromatography (HPLC) is the gold standard for measuring peptide purity. 98%+ is pharmaceutical grade, 95%+ is research grade.

How are lab tests verified on Peptigrity?

Lab tests are submitted by community members with original certificates from accredited third-party laboratories. Each submission is reviewed before publication.

Are testing laboratories affiliated with Peptigrity?

No. There is no business relationship or payment from any testing laboratory listed on the platform.

How do I submit my test results?

Registered users can submit lab test results through the submission form. You need the original certificate of analysis from the testing laboratory.

No ISO/IEC 17025 accreditation on file

ILS Laboratories is not currently listed as ISO/IEC 17025 accredited — the international standard for testing and calibration laboratories. This is not unusual in the peptide testing market (most listed labs lack it). Accredited results carry more regulatory weight in formal contexts. Read about lab accreditation standards →

About ILS Laboratories

ILS Laboratories is an ISO/IEC 17025 accredited analytical laboratory in San Diego, California (8222 Vickers St, Suite 106), providing HPLC purity verification, LC-MS identity confirmation, endotoxin screening, sterility testing, and elemental impurity analysis per USP <233> for research-use-only peptides and supplements.

ILS is one of four laboratories in Peptigrity's testing-labs index with documented current ISO accreditation. CoAs are signed by named PhD-level chemists, which adds an evidentiary signal beyond unsigned reports — the certificate explicitly states accreditation status and pharmacopoeial methodology references.

What sets ILS Laboratories apart

✓ISO/IEC 17025 accredited — one of four laboratories in Peptigrity's testing-labs index with current ISO accreditation. The lab's CoAs explicitly carry the accreditation reference and pharmacopoeial method numbers, relevant for buyers evaluating evidentiary weight.
✓Full safety-relevant panel under one roof — HPLC purity, LC-MS identity, endotoxin, sterility, and elemental impurities (per USP <233>). The complete injectable-relevant safety stack from a single accredited lab, without subcontracting.
✓Chemistry and microbiology under the same roof — most peptide labs offer chemical analysis only and subcontract microbiology; ILS runs both in-house, relevant for buyers needing combined purity + sterility panels.
✓Named, signed CoAs — documented evidence of PhD-level chemists (e.g., Dr. Greg Kalyuzhny on at least one published certificate) signing reports, an evidentiary signal absent from labs that publish unsigned CoAs.
✓USP-compendial methodology references — elemental impurities analyzed per USP <233>. Methods documented against United States Pharmacopeia chapters rather than ad-hoc internal protocols.

Honest disclosures

ISO 17025 accreditation scope on a CoA applies only to the specific methods and items listed. Buyers should review the lab's accreditation scope document for the specific tests they're commissioning to confirm coverage.
Pricing is not published on the lab's homepage — quoted per submission.
Acceptance criteria stated as "internal laboratory quality screening limits for research-use materials" — results do not represent evaluation against specific pharmacopoeial monographs or route-of-administration standards. Buyers wanting pharmacopoeial-monograph evaluation should request that explicitly.
