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.
99.39%
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 purity confirmed
99.39% purity by HPLC with conformity testing (2 samples: 99.39%, 99.21%; mean 99.30%, std dev 0.09%). This is normal for research peptides and supported by chromatogram and duplicate testing.
Identity confirmed
Double Agonist confirmed by HPLC retention time match with reference standard. Fentanyl screen negative (immunoassay, 50 ng/mL cutoff).
Batch information complete
Lot CR-2XAG20-2605-1, COA #COA-2026-JCGGMS, Accession #ACC-2026-3292. Net peptide content 20.91 mg (labeled 20 mg).
Dates consistent and valid
Received 05/27/2026, analyzed 06/01/2026, issued 06/01/2026. All dates are on or before 2026-07-28 (today) and logically ordered.
Lab information present
ILS Laboratories, 8222 Vickers St, Suite 106, San Diego, CA 92111. ISO/IEC 17025 accredited. Signed by Dr. Greg Kalyuzhny, Lab Director. Verification URL and access code provided (YFUPGRB6).
Comprehensive testing panel
Five panels present: identity (HPLC-RTM), purity (HPLC), heavy metals (ICP-MS), endotoxin (USP <85>), sterility (PCR). All tests passed. Microbial and residual solvent/water panels not included.
Professional presentation
Two-page COA with clear tables, HPLC chromatogram, conformity testing results, QR code for verification, detailed methodology notes, and ISO/IEC 17025 accreditation statement.
Lab verification recommended
While the COA appears professionally formatted and internally consistent, independent verification of ILS Laboratories' accreditation status and the provided verification URL (portal.ils-lab.com/verify/6dIiIViOcJGg9Z4n) is recommended as part of standard due diligence.
