Public COA audit
GLP3-R · GLP-1 receptor agonist (implied)
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 88
- Confidence
- 92%
- Panels
- 3/7
- Purity (printed)
- 99.93%
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).
GLP RT confirmed by mass spectrometry
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.93% average (Vial 1: 99.92%, Vial 2: 99.96%, Vial 3: 99.92%)
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.
≤ 0.05 EU/mL (both replicates)
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 across three vials
Average purity 99.93% with consistent results across all three vials (99.92%, 99.96%, 99.92%). This is normal for research-grade peptides.
Mass spectrometry confirmation provided
LCMS/MS data shows expected mass peaks ([M+3H]3+ and [M+4H]4+) consistent with GLP-1 receptor agonist peptide identity.
Endotoxin testing performed
Two replicates both passed at ≤ 0.05 EU/mL threshold, appropriate for research-grade material.
Batch/lot number clearly stated
Lot CRRT-15-0212-01 with accession number 2602150021 and search code Crus2602150021 for verification.
Dates are current and logical
Received 02/16/2026, reported 02/17/2026 (next-day turnaround). Both dates are on or before today (2026-09-05).
Lab identification and contact provided

Limited panel scope
This COA covers purity, identity, and endotoxin only. Heavy metals, microbial contamination, sterility, and residual solvents/water content were not tested in this report.
Professional presentation with supporting data
Includes HPLC chromatogram, mass spectrum, and product photos. Clear disclaimer about research use only.
