Public COA audit
Semax
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 93%
- Panels
- 3/7
- Purity (printed)
- 99.8%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 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.
3 of 7 present · 3 passed · 0 failed · 0 reported · 4 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).
FTIR sample spectrum confirms the presence of Semax with addition of excipient(s)/fillers
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.8%
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
Tested · passed · core
LAL or chromogenic endotoxin assay.
14.9 EU/vial (limit: 40 EU/vial)
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 HPLC purity confirmed
HPLC purity of 99.8% meets specification (≥98%). This is normal for research-grade peptides.
Identity confirmed by FTIR
FTIR spectrum confirms presence of Semax with excipients/fillers. Potency assay shows 94.2-102.1% of labeled 10mg content across triplicate measurements.
Endotoxin testing performed separately
This is a multi-document COA set. Page 1-2 cover purity/identity/potency (report IF-824-QSA-TR006-BTL26130-04). Page 3 is a separate endotoxin report (IF-824-QSA-TR006-BTL26130-23, dated 4/10/2026) for the same lot CR-SMX10-2603-1, showing 14.9 EU/vial (PASS, limit 40 EU/vial).
Lot number clearly stated
Lot CR-SMX10-2603-1 is consistent across all three pages of the COA set.
Dates are valid and consistent
Main report dated 4/5/2026 (tested 4/2/2026), endotoxin report dated 4/10/2026 (tested 4/8/2026). All dates are on or before today (2026-09-05) and follow logical sequence.

Professional presentation
Report includes QR code, watermarks, triplicate measurements, FTIR and HPLC chromatograms, detailed sample description, and USP method references.
Some panels not included
Heavy metals, microbial contamination, sterility, and residual solvents/water content were not tested. The Testing Purpose section explicitly states the report does not cover particulate matter, microbial contamination, or presence of endotoxins (though endotoxin was tested separately). This is common for research-grade peptide testing.
