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).
BPC-157/Thymosin Beta-4 confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.30%
Heavy metals
Not on this COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Microbial
Not on this COA
Bioburden / microbial limits testing.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
Pass (both replicates)
Sterility
Not on this COA
Sterility testing where applicable.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High purity confirmed
HPLC-UV purity of 99.30% is within normal range for research peptides. Two vials tested with consistent results (99.29% and 99.31%).
Identity confirmed by LC-MS
Both BPC-157 and Thymosin Beta-4 confirmed present via mass spectrometry with chromatogram and mass confirmation data provided.
Endotoxin testing performed
Duplicate endotoxin testing passed with sensitivity ≤0.05 EU/mL per USP <85> standards.
Batch and net content documented
Lot number BPTB20-052026-4 with net content measurements for both compounds in both vials. Slight overfill noted (11.61mg vs 10mg labeled for BPC-157, 10.23mg vs 10mg for TB-500).
Dates within acceptable range
Received 2026-05-21, reported 2026-05-23 (2-day turnaround). Both dates are before current date of 2026-07-28.
Lab verification limited
Freedom Diagnostics Testing appears to be a smaller/newer testing facility. Website and contact information provided but independent verification of accreditation status not possible from document alone.
Limited testing panel scope
Heavy metals, microbial contamination, sterility, and residual solvents/water content not tested. This is common for basic peptide COAs but represents incomplete characterization.
Professional presentation
Document includes chromatogram, mass spectra, signature, QR code, and appropriate research-use-only disclaimers. Layout is consistent with legitimate testing reports.
