Testing labs
Peptide testing labs, compared on what we could verify
The 10 labs named on the certificates of analysis (COAs) published by the vendors we track, checked on Oct 16, 2026: who runs them, whether they are accredited, what they test, what they charge and how to check a COA. Every fact links to its source.
Two of the 10 labs hold ISO/IEC 17025 accreditation we could verify, and neither certificate covers peptide testing. ILS Laboratories (scope: cannabis and hemp [source]) and Ethos Analytics (scope: supplements and cosmetics [source]). Vanguard Laboratory is listed in A2LA's directory, but its certificate's scope could not be viewed. We found no accreditation for the other 7, in the A2LA, IAS and PJLA directories (and the Czech Accreditation Institute's, for Janoshik).
Two labs list a fee for issuing a COA under an additional company name, Freedom Diagnostics ($50) and ILS Laboratories ($100), so the same test can appear on more than one brand's COA.
The labs
| Lab | Vendors naming it | Accreditation | Check a COA |
|---|---|---|---|
| Freedom Diagnostics | 25 | None found | Online lookup by code |
| Janoshik Analytical | 25 | None found | Not confirmed (site blocked) |
| Chromate | 11 | None found | Online lookup (job number and code) |
| ILS Laboratories | 11 | ISO/IEC 17025 (PJLA), but the scope covers cannabis and hemp only | QR code and online lookup |
| Kovera Labs | 11 | None found | Online lookup by COA ID |
| Finnrick | 9 | Not a lab: partner labs run the tests | Online lookup (sign-in needed) |
| Vanguard Laboratory | 6 | Listed by A2LA; scope could not be viewed | None on the COAs we saw |
| Horizon Analytical | 4 | None found | Online lookup by report number |
| MZ Biolabs | 4 | None found | None described |
| TrustPointe Analytics | 4 | None found | QR code and online lookup |
| Ethos Analytics | 0 | ISO/IEC 17025 (PJLA), but the scope covers supplements and cosmetics | Online lookup |
Vendors naming it: how many of the vendors we track name the lab on the COAs they publish. Finnrick is a ratings platform that sends samples to partner labs, so it holds no accreditation of its own. SGS, a large international testing company, is named on one vendor's COAs and was not researched further.
Peptide testing labs: questions people ask
Is Janoshik accredited?
We found no accreditation for Janoshik Analytical: it was not in the directories of the Czech Accreditation Institute, A2LA, IAS or PJLA when we searched on Oct 16, 2026. Its own website blocked our checks, so we couldn't see whether it claims one. See the Janoshik Analytical profile.
Which peptide testing labs are ISO 17025 accredited?
Of the 10 labs named on the vendors' COAs we track, ILS Laboratories and Ethos Analytics hold ISO/IEC 17025 accreditation we could check on the accreditation body's own certificate, and neither certificate's scope lists peptide testing. Vanguard Laboratory is listed by A2LA, but its certificate's scope could not be viewed. We found none for the other 7.
How much does it cost to test a peptide?
For a single peptide, a basic identity, purity and quantity test costs $180 to $400 a sample at the labs that publish prices, depending on the lab and the compound; blends cost more, up to $800. See Freedom Diagnostics, Chromate, ILS Laboratories, TrustPointe Analytics and Horizon Analytical. Finnrick, which sends samples to partner labs, lists custom testing from $69 a sample and free community testing whose results it publishes. Endotoxin, sterility and heavy-metal tests usually cost extra.
Can I send a peptide sample to a lab myself?
Some labs say they test for individuals: Freedom Diagnostics, Chromate, MZ Biolabs, Janoshik Analytical and Finnrick, according to their own pages or, for Janoshik, press reports. Others serve businesses, and Kovera Labs says submission is currently open to approved partners only. Each profile quotes what the lab says.
