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
- 88
- Confidence
- 87%
- Panels
- 1/7
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (1/7), and 2 soft concerns. 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.
1 of 7 present · 1 passed · 0 failed · 0 reported · 6 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
Not on this certificate file · core
Compound identity confirmed (e.g. HPLC, mass spec).
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.”
Purity
Not on this certificate file · core
Reported purity percentage for the analyte.
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.”
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.
< 0.20 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.
Endotoxin-specific report
This is a dedicated endotoxin testing report. The absence of purity/identity panels is expected for this document type. This may be part of a split-report system where purity/identity are documented separately.
Professional lab presentation
BioRegen branding with validation key (PEPPART901), report ID (PP-ENDO-250919-133), QR code for verification, and detailed reagent traceability (Thermo Fisher kit A39553, standard OC86T80400, plate reader Q33326).
Proper endotoxin methodology
Chromogenic LAL assay with appropriate controls (positive at 0.25 EU/mL, negative), detection range 0.01-1.0 EU/mL, result < 0.20 EU/mL passes stated threshold of 0.1 EU/mL.
Clear lot identification
Lot number YC20250807 clearly stated with product name MOTS-c, concentration 10mg, 2 vials received.
Valid test date
Test date 09/19/2025 is within acceptable range (before current date 2026-09-05) and matches analyst signature date.
Minor interpretation inconsistency
Interpretation states result is 'below the acceptable threshold of 0.1 EU/mL' but measured value is < 0.20 EU/mL. While the sample passes, the threshold statement could be clearer about whether 0.1 or 0.2 is the actual limit.
Cannot independently verify lab
BioRegen lab identity and www.bioregen.com domain cannot be independently verified from this document alone. Validation key and QR code are provided for verification but not tested here.
