Peptide testing labs, what they charge and who's independent

Every lab that shows up on the certificates our vendors post, with the price each one publishes, what it tests, and whether it takes a sample from you.

These are the labs whose names turn up on the certificates of analysis posted by the vendors we track. Each row shows what the lab says on its own site: what it tests, what it charges, and how long it takes. Where a lab doesn't publish a price, the row says so, and we never fill the gap with a guess.

Not sure where to start? Our guide on how to get your peptides tested walks through the whole process, step by step.

PPL lists labs and doesn't recommend one. No lab pays to be here, and we don't earn anything when you order a test.

Held by 'ILS Labs, Inc. dba Quality Cannabis Laboratories' at the same suite; the earlier 'not found on PJLA under ILS' was a naming miss. The 8-page scope is entirely cannabis (pesticides, cannabinoids, solvents, terpenes, metals, microbial, sampling); no peptide test is in scope, and the ILS site says so. Peptide certificates nonetheless print 'ISO/IEC 17025 Accredited' (Apr-May 2026 template) or refer to the PJLA scope (Aug-Sep 2026).

Checked October 19, 2026 Source

Under "What we checked", Confirmed means we found it on the lab's own site or certificates. Could not confirm means we looked and couldn't find it, which isn't the same as a problem. Found a problem means we found something wrong, such as a mail drop in place of a lab address. Not on the certificate means the lab's own certificates don't show it. Not checked yet means we haven't looked.

Prices and details come from each lab's own website and were last checked on November 2, 2026. Labs change their prices, so check the lab's page before you order. "Not stated" means the lab's site doesn't say, not that the answer is no.

Questions

How much does a peptide testing lab charge?

It depends on the lab and the test. Among the labs that publish a price, a basic purity test starts at $120 to $250 per sample as of November 2, 2026, and some labs charge more for harder compounds or blends. Contamination tests like endotoxin and sterility cost extra.

Can I send a lab my own vial?

Yes. Every lab we've checked tests single samples from individuals, and the prices they list are for one sample. Business accounts and bulk orders usually mean emailing the lab for a quote.

What does "independent" mean here?

It means we found no ownership tie between the lab and a vendor it tests for. "Unverifiable" means we couldn't confirm who runs the lab, usually because there's no street address or registered business we could check.

Are these labs accredited to test peptides?

Some show an ISO 17025 badge, but a badge isn't the same as an accreditation that covers peptides. When we checked the accrediting bodies' own registers, the two labs with confirmed accreditations weren't accredited for peptide purity, which we wrote up in what the labs behind your peptide COA are actually accredited to test.

Why isn't a lab I've heard of listed?

The directory covers labs that appear on certificates from vendors we track. If a vendor we list starts using a new lab, it's added once we've checked it. Labs that aren't taking new clients, or have no website we could check, are left out.

Can a lab pay to be listed or ranked higher?

No. The table sorts alphabetically unless you pick another sort or filter, and nothing a lab pays could change its row.

PPL lists testing labs for information. We don't recommend a lab, no lab pays to be listed, and we don't earn anything when you order a test.

Research use only. Peptide Price Lab is an editorial calculator. Nothing here is medical advice, a recommendation, or a prescription. Consult a qualified clinician before anything that meets your body.
