Testing labs

Where to get a peptide tested, and what it costs

The 26 labs and testing services that vendors and buyers use, compared on who can send a sample, what a test costs, how long it takes and how results are shared. Everything comes from each lab's own website on Oct 16, 2026, with sources; 12 more blocked our checks (listed below). We haven't sent samples to any of them.

A basic test of one peptide costs USD 150 to 440 at the 11 labs and testing services that publish prices (identity and purity, usually with the amount in the vial); 9 of them list USD 200 to 275. An endotoxin test costs USD 125 to 300 more. Finnrick, which sends samples to partner labs, lists USD 118 to 198 and tests some products free.

"Identity" doesn't mean the same test everywhere. AV Analytics, Bioviridian, Eagle Analytical Services, Freedom Diagnostics, Horizon Analytical, MDx BioAnalytical Laboratory, Ozcanium Analytics, Eurofins, Krause Analytical, MZ Biolabs, SideChain Analytics, United Laboratories and Verum Analytics confirm identity by mass spectrometry, which measures the molecule's mass. Testides, Uzorak, Accumark Labs, Chromate, ILS Laboratories, PharmLabs and TrustPointe Analytics match the HPLC retention time against a reference standard, which shows a peak where the standard's appears but doesn't measure the mass. "Sterility" varies too: a culture test to USP <71> at some labs, a DNA screen or microbial count at others (how each lab tests).

Prices are as listed, before tax and shipping, in the currency shown. Labs change prices often: check the lab's own page before you order. A lab's verdict (real, accredited, not confirmed) is from our check of every lab name.

Research peptide testing cost, lab by lab

Labs and testing services that publish prices on their own sites. "Basic test" is identity, purity and quantity for one single peptide, or the nearest package the lab sells.

How each lab tests: identity, sterility and the report

What each lab's own pages say about its methods. Mass spectrometry (MS) measures the molecule's mass; HPLC retention time only shows a peak where a reference standard's appears. Purity by HPLC doesn't show how much peptide the vial holds: that's the quantity, or net peptide content, test.

Testing from outside the US

Uzorak, Eagle Analytical Services and United Laboratories say they accept samples from other countries. Ozcanium Analytics serves Australia and SideChain Analytics Canadian addresses; Finnrick takes US shipments only. Press reports say Janoshik, in the Czech Republic, tests samples sent from abroad, but its site blocked our checks, so we couldn't read its terms. Horizon Analytical takes samples from abroad only with its prior written approval and permits. Check the lab's own intake rules before you ship.

How to choose a lab

  1. Check the lab is real. Look up its name in our check of every lab name: some names on COAs have no laboratory behind them that we could find.
  2. Ask how it confirms identity. Mass spectrometry measures the molecule; retention time alone doesn't (methods above).
  3. Ask for the amount, not just purity. A vial can be 99% pure and still hold less peptide than its label says.
  4. Check what its accreditation covers. ISO/IEC 17025 applies only to the tests on the certificate's scope; only a few labs' scopes cover peptides (testing labs compared).
  5. Check how its reports can be verified. A lookup on the lab's own website lets anyone confirm a report, including the vendor's COAs you compare against.

Peptide testing cost: questions people ask

How much does it cost to test a peptide?

At the 11 labs and testing services that publish prices on their own websites, a basic test of one peptide (identity and purity, usually with the amount in the vial) costs USD 150 to 440; 9 of them list USD 200 to 275. Blends and large peptides cost more. An endotoxin test adds USD 125 to 300. Finnrick, which sends samples to partner labs, lists USD 118 to 198 and tests some products free. Prices as listed on Oct 16, 2026, before tax and shipping.

Where can I send a peptide to be tested?

These labs and services say on their own sites that individuals can send samples: Finnrick, Peptide Test, Testides, Uzorak, Freedom Diagnostics, Horizon Analytical, Ozcanium Analytics, Krause Analytical, MZ Biolabs and SideChain Analytics. Others work only with businesses or approved partners; the tables on this page say which. All of them take samples shipped to the lab.

How long does peptide testing take?

Labs that publish a turnaround quote from a few days (Freedom Diagnostics: 1 to 3 business days on average; Accumark Labs: 48 to 72 hours) to two weeks or more for sterility tests (Peptide Test: 17 to 21 days). Several sell a rush service for an extra fee. Turnaround counts from when the lab receives the sample, so add shipping time.

Do all labs check that the vial holds the right peptide?

Not in the same way. AV Analytics, Bioviridian, Eagle Analytical Services, Freedom Diagnostics, Horizon Analytical, MDx BioAnalytical Laboratory, Ozcanium Analytics, Eurofins, Krause Analytical, MZ Biolabs, SideChain Analytics, United Laboratories and Verum Analytics confirm identity by mass spectrometry in their standard test, which measures the molecule's mass. Testides, Uzorak, Accumark Labs, Chromate, ILS Laboratories, PharmLabs and TrustPointe Analytics match the peak's HPLC retention time against a reference standard instead, which doesn't measure the mass. Ask which method your test uses.

Can I get a peptide tested outside the US?

Uzorak, Eagle Analytical Services and United Laboratories say they accept samples from other countries. Ozcanium Analytics serves Australia and SideChain Analytics Canada; Finnrick takes US shipments only. Press reports say Janoshik, in the Czech Republic, takes samples from abroad, but its site blocked our checks. Check the lab's intake rules before you ship.
