Public COA audit
Double Agonist
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 88%
- Panels
- 5/7
- Purity (printed)
- 99.95%
Scored high because the document is mostly consistent but carries soft concerns, broad panel coverage (5/7), and 1 soft concern.

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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.95%
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.
NMT 0.05 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.
Excellent HPLC purity
99.95% purity with tight conformity testing (mean 99.94%, std dev 0.017%) across 3 samples. This is normal for research-grade peptides.
Identity confirmed by HPLC
Retention time matched reference standard. Chromatogram shows single dominant peak at expected retention time.
Comprehensive testing panel
Full QC Panel includes purity, identity, sterility (PCR), endotoxin (USP <85>), and heavy metals (ICP-MS). Conformity testing on 3 samples demonstrates batch consistency.
Clear lot identification
Lot CRTZ-30-2604-2, COA COA-2026-STQCRC, Accession ACC-2026-0939 with access code UME5P3T8 for verification.
Dates are consistent and current
Received 04/17/2026, analyzed 04/22/2026, issued 04/22/2026. All dates are on or before today (2026-09-05) and show reasonable turnaround time.
ISO/IEC 17025 accredited lab
ILS Laboratories claims ISO/IEC 17025 accreditation. Lab director signature present. Verification URL and QR code provided.
Microbial and residual solvent panels not included
No microbial contamination testing (beyond sterility PCR) or residual solvent/water content analysis visible. This may be acceptable depending on vendor scope, but limits comprehensive quality assessment.
Professional presentation
Two-page report with consistent branding, clear tables, chromatogram, product photo, and verification elements. Formatting is professional and consistent with legitimate lab reports.
