Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
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 certificate file
Bioburden / microbial limits testing.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
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 certificate file
Residual solvents or water content limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
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 on this file
Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. 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 level of purity is normal for research peptides and the conformity testing adds credibility.
Identity confirmed
PT-141 (Bremelanotide) confirmed by HPLC retention time comparison with reference standard across all three conformity samples.
Clear batch identification
Lot CRPT-10-2605-1, COA COA-2026-CSAURK, Accession ACC-2026-2067 clearly stated.
Dates consistent and valid
Received 2026-05-06, analyzed and issued 2026-05-11. All dates are on or before today (2026-09-05) and logically sequenced.
Lab credentials stated
ILS Laboratories, San Diego CA, claims ISO/IEC 17025 accreditation. Verification URL and QR code provided: portal.ils-lab.com/verify/Cp953xy_Jr1hKLo0
Comprehensive testing panel
Document includes identity, purity (HPLC), heavy metals (ICP-MS), endotoxin (USP <85>), and sterility (PCR). Microbial culture and residual solvent/water panels not present but this is common for research peptide COAs.
Professional presentation
Two-page report with consistent branding, clear tables, HPLC chromatogram, signature, and verification elements. Formatting is consistent with legitimate analytical lab reports.
