Public COA audit
Epithalon
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)
- 98.8%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 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.
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).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
98.80%
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.
<0.5 EU
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
98.80% chromatographic purity with 99.2% of label claim (49.6 mg recovered from 50 mg label) is excellent and typical for research-grade peptides.
Mass spectral confirmation
Identity confirmed by HPLC-UV-MS with reference spectrum comparison shown on page 2.
Batch/lot number present
Lot 7yt7grq clearly stated with Lab # 201832 and Project 145100.
Dates consistent
Sample received 2/26/2026, endotoxin tested 2/28/2026, purity/identity tested 3/3/2026, report issued 3/3/2026. All dates are logical and sequential.
Lab identification

Endotoxin testing present
Endotoxin panel present with <0.5 EU result using USP 86 (LAL method), tested 2/28/2026.
Heavy metals panel absent
Methods summary on page 3 describes USP/NF 233 ICP-MS method for metals testing, but no results are reported in this certificate. This may indicate metals testing was not performed for this lot or is reported separately.
Microbial and sterility panels absent
No microbial contamination or sterility testing results are present in this report.
Professional presentation
Document includes chromatogram (page 2), mass spectrum comparison (page 2), detailed methods summary (page 3), and proper watermarking. Formatting is consistent with professional analytical lab reports.
