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 - Bremelanotide (PT-141)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.93%
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.
0.09 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 with conformity testing
99.93% purity confirmed via triplicate HPLC testing (3 samples: 99.93%, 99.75%, 99.88%; mean 99.85%, std dev 0.0759%). This is normal for research-grade peptides and demonstrates rigorous QC.
Identity confirmed
PT-141 (Bremelanotide) confirmed by HPLC retention time comparison with reference standard.
Complete batch information
Lot CRPT-10-2605-1, COA COA-2026-CSAURK, Accession ACC-2026-2067 all clearly documented.
Dates consistent and valid
Received 2026-05-06, analyzed and issued 2026-05-11. All dates are on or before 2026-07-28 (current date) and logically sequenced.
ISO/IEC 17025 accredited lab
ILS Laboratories claims ISO/IEC 17025 accreditation. Address: 8222 Vickers St, Suite 106, San Diego, CA 92111. Phone: (619) 329-3999. Verification URL and QR code provided.
Comprehensive testing panel
Full QC Panel includes HPLC purity/identity, heavy metals (ICP-MS), endotoxin (USP <85>), and sterility (PCR). Microbial and residual solvent/water panels not present but not required for all peptide COAs.
Professional presentation
Two-page COA with consistent branding, clear tables, HPLC chromatogram, signature of Lab Director Dr. Greg Kalyuzhny, and verification access code OQJKFTZ0.
Independent verification recommended
While the COA appears professionally formatted and internally consistent, independent verification via the provided URL (portal.ils-lab.com/verify/Cp953xy_Jr1hKLo0) is recommended to confirm authenticity. ILS Laboratories' accreditation status and existence should be verified through third-party databases.
