Testing labs
The labs and testing programs whose names appear on peptide certificates: what each says it tests, and how to verify its reports on its own site. Alphabetical. These are descriptions, not ratings, and none of these labs pays us.

In short
A third-party peptide testing lab analyses a sample someone sends it and issues a report on that sample only. Most list HPLC purity and mass spectrometry identity; some add amount, endotoxin or sterility. Verify any report on the lab's own website, using the code printed on the certificate.
| Lab / program | Type | Methods it lists | How to verify a report |
|---|---|---|---|
| Chromatechromate.org | US-based analytical service and unannounced testing project | HPLC · Microbiology tests (additional vials required) · Supplement analysis | Results published through the Verify portal on chromate.org |
| Finnrick Analyticswww.finnrick.com | Testing program and public results database (uses partner labs) | Identity · Purity · Fill (amount) · Endotoxin, heavy metals, residual solvents and sterility testing via partner labs | 'Verify a COA' tool on its site |
| Freedom Diagnostics Testingwww.freedomdiagnosticstesting.com | Independent analytical lab | Purity (HPLC) · Identity (LC-MS) · Net content · Endotoxins · Sterility (PCR) · Conformity (additional vials) · Heavy metals · Fentanyl screen · pH | COA Look Up on the lab's website |
| Janoshik Analyticaljanoshik.co | Independent analytical lab (consumer and vendor clients) | HPLC purity and amount · Mass spectrometry identity · Blind screening tests (e.g. GLP-1 identification) · Protein analysis (amount, purity, dimers) for hGH | Task number + unique key on janoshik.co/verify; reports carry a QR code |
| MZ Biolabsmzbiolabs.com | Mass spectrometry and analytical chemistry lab | HPLC-UV purity · Mass spectrometry identity · Quantification of solutions, tablets and capsules · Custom method development | Contact the lab directly using details from its own website |
Testing labs FAQ
Which labs test peptides for third parties?
This hub profiles 5 labs and testing programs whose names appear on peptide certificates: Chromate, Finnrick Analytics, Freedom Diagnostics Testing, Janoshik Analytical, MZ Biolabs. Inclusion is not an endorsement, and the list is alphabetical.
How do I check that a lab report is real?
Use the verification route on the lab's own website (a task number and key, a COA lookup or a verify portal) rather than any link from a seller. Then match the lot number, compound and amount to your vial.
Does a third-party lab report certify a vendor?
No. A report describes only the sample that was sent, chosen by whoever sent it. It says nothing about other lots, other products, or tests that were not ordered.
Are any of these labs paid by Amino Wire or paying Amino Wire?
No. We have no commercial relationship with any lab listed, and we do not rate or rank them. Profiles describe what each lab publishes about itself, with the date we checked.
