Public COA audit
Selank
Audited September 5, 2026
Document structure and test panels align with what we expect from authentic lab reports.
- Legitimacy
- 95
- Confidence
- 95%
- Panels
- 5/7
- Purity (printed)
- 99.67%
Scored high because document structure and panels look consistent with authentic lab output and broad panel coverage (5/7).

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 · 4 passed · 0 failed · 1 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 (Selank)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.67% (mean 99.66%, n=3)
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 · result on file · 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.
High purity with triplicate testing
99.67% purity (mean 99.66%) confirmed across three samples (Dedicated V0, Conformity V1, V2) with low standard deviation (0.0047%), demonstrating excellent batch consistency.
Identity confirmed by HPLC retention time
Selank identity confirmed by HPLC-RTM (retention time match) with reference standard. Chromatogram shows expected peak profile.
Comprehensive testing panel
Full QC panel includes purity/quantitation (HPLC), identity (HPLC-RTM), heavy metals (ICP-MS), sterility (PCR), endotoxin (USP <85>), and fentanyl screening. Five of seven standard panel types present.
Clear batch identification
Lot number CR-SLK5-2605-1, COA number COA-2026-TEHYON, Accession ACC-2026-3099. All identifiers clearly stated.
Dates are consistent and valid
Sample received 2026-05-22, analyzed 2026-06-01, issued 2026-06-01. All dates are on or before 2026-09-05 (today) and show reasonable turnaround time (10 days).
ISO/IEC 17025 accredited lab
ILS Laboratories, San Diego, CA. Document states ISO/IEC 17025 accreditation. Verification URL and QR code provided (portal.ils-lab.com/verify/P1SUxKNXG44ClNv5). Access code CR9T6MKD.
Endotoxin testing present
Endotoxin tested per USP <85> kinetic turbidimetric method. Result: NMT 0.05 EU/mL. Document notes this is below commonly referenced thresholds and that no universal pass/fail applies to RUO products.
Professional multi-page format
Three-page COA with consistent branding, clear tables, HPLC chromatogram, methodology notes, and lab director signature. Professional presentation consistent with accredited lab standards.
