Public COA audit
Thymosin Alpha 1
Audited September 5, 2026
Missing panels or key metadata — not enough evidence to treat this as a full certificate.
- Legitimacy
- 62
- Confidence
- 78%
- Panels
- 2/7
Scored lower because the file is incomplete or not a full COA, limited panel coverage (2/7), 2 critical findings, and notable note: "No purity testing". To improve: upload the full certificate (or the matching sibling purity/endotoxin report) and 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
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
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: 0.003 ppm, Cd: <0.001 ppm, Hg: <0.001 ppm, Pb: <0.001 ppm
Microbial
Tested · passed
Bioburden / microbial limits testing.
TAC: 400 cfu/g, Coliforms: <10 cfu/g, E.coli: Absent, Salmonella: Absent, Staph: Absent, Yeast/Molds: <100 cfu/g
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.
No purity testing
This COA lacks any HPLC, MS, or other purity/assay data for Thymosin Alpha 1, which is essential for peptide quality verification.
No identity confirmation
No mass spectrometry, amino acid analysis, or other identity verification method is documented. Only appearance and flavor are noted.
Missing endotoxin testing
No bacterial endotoxin (LAL/BET) testing is shown, which is important for injectable peptides.
Heavy metals tested
Comprehensive heavy metals panel (As, Cd, Hg, Pb) via USP 233, all results conform to specifications.
Microbial testing present
Full microbial panel including aerobic count, coliforms, pathogens, and yeast/molds via USP methods, all conforming.
Lot number present
Lot L1165 clearly identified.
Lab verification unclear
InstaMed is identified as the testing lab, but no website, contact information, or verification URL is provided to independently confirm the lab's credentials or this report.
Appearance/flavor testing unusual
Organoleptic testing (appearance: orange, flavor: characteristic of orange) is atypical for a research peptide COA and suggests this may be a food/supplement product rather than a pharmaceutical-grade peptide.
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (417 days) — consider whether a retest is warranted for this batch.
