7-panel checklist
Had data + good, had data + bad, reported without pass/fail, or missing. Missing lowers thoroughness — you decide whether that panel matters; PeptIQ’s score still factors coverage.
5 of 7 present · 5 passed · 0 failed · 0 reported · 2 missing
Missing is a thoroughness gap — not automatically bad. PeptIQ’s legitimacy score still weighs panel coverage; you can down-weight panels that don’t matter for your use case.
Identity
Tested · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.69%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
All Not Detected (As, Cd, Cr, Hg, Pb)
Microbial
Not on this COA
Bioburden / microbial limits testing.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
NMT 0.05 EU/mL
Sterility
Tested · passed
Sterility testing where applicable.
No Growth
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
How to read this
Had data · good
Panel present with a pass (or clear acceptance).
Had data · bad
Panel present with a fail — a concrete quality signal.
Had data · unclear
Value reported without an explicit pass/fail mark.
Missing
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High HPLC purity with conformity testing
99.69% purity confirmed across three conformity samples (mean 99.61%, std dev 0.0579%), which demonstrates batch consistency and is normal for research-grade peptides
Identity confirmed by HPLC
Cagrilintide confirmed by chromatographic retention time comparison with reference standard; chromatogram provided
Comprehensive testing panel
Full QC Panel includes purity, identity, sterility (PCR), endotoxin (USP <85>), and heavy metals (ICP-MS per USP <233>). Net peptide content reported as 5.23 mg
Clear batch identification
Lot number CRCAG-5-2604-1, COA number COA-2026-UIFCEW, Accession ACC-2026-0947
Dates are consistent and valid
Received 04/17/2026, analyzed 04/22/2026, issued 04/22/2026. All dates are on or before 2026-07-28 and follow logical sequence
Lab credentials and verification provided
ILS Laboratories claims ISO/IEC 17025 accreditation, provides physical address (8222 Vickers St, Suite 106, San Diego, CA 92111), phone number, verification URL with access code VSA9C-6R, and QR code for authentication
Professional presentation
Two-page COA with consistent branding, clear tables, HPLC chromatogram, lab director signature, and conformity testing results table
Independent verification recommended
While the COA appears professionally formatted with verification URL provided, independent verification of ILS Laboratories' accreditation status and the specific verification URL is recommended as standard practice
