Public COA audit
Selank
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 2/7
- Purity (printed)
- 99.42%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "High purity confirmed". To improve: include identity, purity, and endotoxin at minimum.

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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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).
Selank confirmed, MS shows expected molecular ion
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.42%
Heavy metals
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar 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.”
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
Sterility
Not on this certificate file
Sterility testing where applicable.
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.”
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 confirmed
99.42% purity by UPLC is excellent and within normal range for research-grade peptides
Identity confirmed by UPLC/MS
Both chromatographic and mass spectrometric data provided, showing expected molecular weight region
Purity-scoped lot number
Lot number RRL-4692745-P has '-P' suffix suggesting this is a purity/identity-focused report. Additional testing (endotoxin, microbial, etc.) may exist in separate reports with different suffixes
Recent analysis dates
Lab received 2026-07-05, analysis conducted 2026-07-09 - both dates are valid and recent relative to current date 2026-09-05
Lab verification needed
Horizon Analytical appears professional with contact information and verification QR code, but independent verification of lab credentials recommended
Limited testing scope
This report covers purity and identity only. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing shown on this document. This may be intentional for a purity-focused report, but users should verify if additional safety testing exists
Professional presentation
Document includes proper header, client information, compound details, analytical methods, chromatograms, mass spectrum, QR validation code, and analyst signature
