Public COA audit
Semax · Selank
Audited July 28, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 93%
- Panels
- 4/7
- Purity (printed)
- 99.9%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (4/7), and 1 soft concern. 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.
4 of 7 present · 4 passed · 0 failed · 0 reported · 3 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, Semax
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.9%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
<0.01 ppm
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.
<0.05 EU/mL
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
99.9% purity by RP-HPLC is excellent and typical for research-grade peptides
Dual identity confirmation
Both MALDI-MS identity and HPLC chromatogram with mass spectrum provided, showing expected molecular ions for Selank and Semax
Core safety panels present
Identity, purity, heavy metals, and endotoxin testing all performed and passed
Clear batch identification
Lot number SEMSEL5-0616 clearly stated
Recent testing with appropriate timeline
Sample received 2026-06-19, COA issued 2026-06-25 (6-day turnaround is reasonable)
Professional presentation
Bioviridian COA with verification URL, QR code, and signature from Principal Chemist Shane Straight, M.S.
Complete documentation
Includes chromatogram with retention time (1.759, 8.465 min), mass spectrum, product image, and all standard COA elements
Microbial and sterility testing not performed
No microbial limit or sterility testing reported; acceptable for research use but users should be aware
