Public COA audit
GLP3-R · GLP-1 receptor agonist
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 3/7
- Purity (printed)
- 99.94%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 3 soft concerns, and notable note: "High purity confirmed". 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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.94% average (Vial 1: 99.98%, Vial 2: 99.94%, Vial 3: 99.91%)
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
Average purity 99.94% across three vials (99.98%, 99.94%, 99.91%) is excellent and typical for research-grade peptides. HPLC chromatogram shows single dominant peak consistent with stated purity.
Mass spec confirmation present
Mass spectrometry data shows [M+3H]3+ and [M+4H]4+ ions consistent with GLP-1 receptor agonist peptide identity verification.
Endotoxin testing performed
Endotoxin testing completed with two replicates, both passing at ≤ 0.05 EU/mL threshold, appropriate for research peptides.
Lab verification limited
Freedom Diagnostics website (FreedomDiagnosticsTesting.com) and verification system cannot be independently confirmed. Lab claims USA operation but provides minimal accreditation details.
Batch documentation complete
Lot number CRRT-15-0126-01 clearly stated with accession number 2601080270 and search code for verification.
Timeline reasonable
Received 2026-01-08, reported 2026-01-11 (3-day turnaround) is plausible for HPLC/MS and endotoxin testing.
Limited testing scope
COA only includes purity, identity, and endotoxin panels. Missing heavy metals, microbial, sterility, and residual solvent/water testing. This is common for basic research peptide COAs but limits comprehensive quality assurance.
Product photos included
COA includes photos of labeled vials with 'CRUSH' branding. While this adds traceability, it's unusual for third-party lab reports and suggests possible vendor-lab relationship or in-house testing.
