Public COA audit
DSIP
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 83%
- Panels
- 1/7
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (1/7), 2 soft concerns, and notable note: "Endotoxin-only report". 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-only report
This is a specialized endotoxin testing report only. It does not include purity, identity, or other panels. This is a common practice where vendors issue separate reports for different test types (e.g., purity/HPLC report separate from endotoxin report).
Endotoxin test passed
DSIP sample measured < 0.20 EU/mL using chromogenic LAL assay, passing the stated threshold of 0.1 EU/mL. Positive and negative controls both performed as expected.
Lab verification needed
BioRegen is listed as the testing lab with [email protected] and www.bioregen.com. The document includes a validation key (PEPPART901) and QR code for verification, but independent confirmation of this lab's accreditation and the validity of this report ID is recommended.
Interpretation inconsistency
The interpretation states the result '< 0.20 EU/mL indicates that the endotoxin content is below the acceptable threshold of 0.1 EU/mL' — but a result of < 0.20 EU/mL does not definitively prove the level is below 0.1 EU/mL (it could be anywhere from 0.1 to 0.19 EU/mL). This is a minor technical imprecision in the report language.
Lot number present
Lot number DS20250820 clearly stated for DSIP product.
Test date valid
Test date 09/19/2025 is within acceptable range (before today's date of 2026-09-05).
