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).
Thymosin Alpha-1 confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.51% average (Vial 1: 99.41%, Vial 2: 99.52%, Vial 3: 99.61%)
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.
Replicate 1: ≤ 0.05 EU/mL, Replicate 2: ≤ 0.05 EU/mL
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
Average purity of 99.51% across three vials is consistent with quality research-grade peptide synthesis
Mass spectrometry confirmation
Chromatogram and mass spectrum showing [M+4H]4+ at 777.68 and [M+3H]3+ at 1036.58 consistent with Thymosin Alpha-1
Endotoxin testing performed
Duplicate endotoxin testing with passing results (≤ 0.05 EU/mL) indicates attention to safety parameters
Limited lab verification information
Freedom Diagnostics website and contact provided, but no physical address, accreditation details, or third-party verification available on document
Missing standard panels
No heavy metals, microbial contamination, sterility, or residual solvent/water content testing reported
Inconsistent date formatting
Received date shows '02/16/2026' while Reported date shows '2/17/2026' - minor inconsistency in formatting style
Batch information complete
Lot number CR-TAT10-0212-1 clearly stated with individual vial measurements
Appropriate turnaround time
One-day turnaround from receipt (02/16/2026) to report (02/17/2026) is reasonable for HPLC/MS analysis
