Public COA audit
DSIP · DSIP 5 MG
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
- 2/7
- Purity (printed)
- 99.2%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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).
99.2%
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.2%
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
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
HPLC purity of 99.2% is excellent and typical for research-grade peptides. Chromatogram shows clean single peak.
Identity confirmed by MS
Mass spectrometry data provided showing [M+H]+ peak at 849.98 m/z, consistent with DSIP molecular weight. HPLC-MS combination provides strong identity confirmation.
Batch information complete
Lot number DSIP10202025-J clearly stated with accession number 2510220149
Dates are valid and recent
Received 2025-10-22, reported 2025-10-25. Both dates are in the past relative to 2026-09-05 and show reasonable turnaround time.
Lab identification present
Freedom Diagnostics identified as testing lab with website FreedomDiagnosticsTestInc.com and contact email. States 'Proudly Owned and Operated in the USA'.
Limited testing scope
This COA only covers identity and purity testing via HPLC-MS. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing included. This is common for basic purity reports but limits comprehensive quality assessment.
Professional presentation
Document includes company branding, clear data tables, chromatogram, mass spectrum, and product photo. Signature from Principal Chemist Stephen Schmidt present.
