Public COA audit
MOTS-C
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
- 5/7
- Purity (printed)
- 99.57%
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.
99.57%
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 purity with conformity testing
99.57% purity confirmed across 3 independent samples (98.55%, 99.48%, 99.57%) with low standard deviation (0.46%). Mean purity 99.20%. HPLC chromatogram shows clean single peak.
Identity confirmed by HPLC retention time
MOTS-C identity confirmed by HPLC-RTM with reference standard comparison. All three conformity samples passed identity verification.
Comprehensive testing panel
Full QC panel includes purity/identity (HPLC), heavy metals (ICP-MS), endotoxin (USP <85>), sterility (PCR), and fentanyl screening. Missing only microbial count and residual solvents/water content.
Clear batch identification
Lot CRMTS-40-2605-1, COA #COA-2026-E85OFQ, Accession #ACC-2026-3349. Net peptide content 41.8 mg vs labeled 40 mg (104.5% of label claim).
Appropriate timeline
Received 2026-05-27, analyzed and issued 2026-06-01 (5-day turnaround). All dates are on or before the authoritative current date of 2026-09-05.
ISO/IEC 17025 accredited lab
ILS Laboratories, San Diego CA. Claims ISO/IEC 17025 accreditation. Provides verification URL, access code (MN4SR7XQ), and QR code for authenticity verification.
Professional presentation
Well-formatted 2-page report with clear tables, chromatogram, methodology notes, and lab director signature. Consistent branding and layout.
Microbial enumeration not performed
Sterility testing (PCR) is present, but total aerobic/yeast/mold counts are not reported. This is common for research-grade materials but would be expected for pharmaceutical-grade products.
