Peptide testing cost: how much a test costs in 2026, what drives the price and what costs extra

How much it costs to test peptides: the three parts of a bill

A peptide testing bill has three parts. The core test says what is in the vial: identity, purity and content in mg. The safety tests, endotoxin and sterility, look for contamination and often need vials of their own. The extras change the report or the timing: raw data, more vials from the same batch, rush, and extra copies of the report. Two quotes for “a peptide test” can differ by hundreds of dollars because one includes safety tests and extras and the other does not.

Every price on this page is a published list price, in US dollars unless stated, checked September 2026 unless another date is given, before shipping and tax. Many labs quote instead of publishing prices, and a quote can differ from a list. For each lab’s full price list side by side, use the peptide testing price comparison. This page explains what the prices are made of.

Typical published prices by test

Test	Published range	Examples from lab price lists
Core test, common peptide (identity, purity, mg)	$150–$325	Bioviridian $150; Chromate $180 for BPC-157; TrustPointe $200 for TB-500; Janoshik $215 for BPC-157; Freedom Diagnostics $225 with net content; Accumark $250 for any peptide; Horizon $325
Core test, GLP-1 or less common peptide, at labs that price per peptide	$300–$450	Chromate $300 for semaglutide, tirzepatide or retatrutide and $380 for cagrilintide; Janoshik $360 for its blind GLP-1 test and $450 for many less common peptides; TrustPointe $400 for retatrutide
Blends, at labs that price per component	$320–$800	Janoshik $320 for BPC-157 with TB-500 and $800 for a four-peptide blend; Horizon $400 for two components and $650 for four; TrustPointe $400–$800
Endotoxin (LAL)	$150–$300	Bioviridian $150; PharmLabs $160; Freedom Diagnostics $175; Janoshik $180; Accumark and Horizon $200; Vanguard $210; Chromate $240; TrustPointe $300
Sterility by USP <71> (14 days)	$150–$300	Vanguard $150; Bioviridian $200; Accumark $250; TrustPointe $300
Other microbial tests sold as “sterility”	$150–$290	Freedom Diagnostics PCR screen $150; PharmLabs microbial count $220; Accumark PCR screen $230; Janoshik microbial count (TAMC and TYMC) $290

Two things stand out. The same named test can cost twice as much at one lab as at another. And the same name can cover different work. Some core tests prove identity by mass spectrometry and some by HPLC retention time. Some include content in mg and some charge for it: Freedom Diagnostics adds $25 for net content to its $200 purity and identity test. Compare what each test measures before you compare the peptide testing price. The core test is covered in detail in peptide purity testing cost.

What drives peptide testing cost

1. The tests you choose. A core test alone is the smallest bill. Each safety test adds $150–$300 at the labs above.
2. The peptide. Labs that price per peptide charge more for GLP-1s, longer peptides and less common ones. Chromate lists BPC-157 at $180 and cagrilintide at $380. Janoshik lists BPC-157 at $215 and many less common peptides at $450. Content in mg is measured against a reference standard of the same peptide, so each peptide needs its own standard and method set-up. Accumark charges one price, $250, for any peptide.
3. Blends. Each component has to be identified and measured. TrustPointe lists BPC-157 with TB-500 at $400 and its four-peptide KLOW blend at $800. Analytical Formulations adds $50 per extra compound. Accumark’s flat price includes blends. See peptide blend testing.
4. Vials. Endotoxin and sterility often need extra vials, and you pay for those vials too. Freedom Diagnostics asks for an additional vial for each. Bioviridian needs two vials for sterility. Vanguard’s Gold package uses three vials. How many vials a test needs has the details.
5. Volume. Many labs cut the price per sample on larger orders. ILS takes 5% off 15–29 samples, 10% off 30–49 and 20% off 50 or more. Horizon’s core test falls from $325 for one sample to $225 each in a 10-sample bundle. Bioviridian’s price does not change with quantity.
6. Shipping, tax and payment. Most labs expect you to ship at your own cost. CheckPeptide sells a kit with vials, packaging and a prepaid return label for $25 more. Prices outside the US may include or exclude sales tax. Payment timing differs too: ILS bills when results are ready, and Horizon asks for payment before testing begins.

What is often extra

Extra	Published prices	Notes
Raw data (chromatograms, spectra)	Janoshik $25	Peptide Test Canada includes raw HPLC data in its standard test
Extra vial of the same batch	$50–$100	Freedom Diagnostics, ILS, Chromate and Analytical Formulations $50; Janoshik $75 for variance testing; Vanguard $100 for one to three extra vials
Rush	From $100 more to four times the base price	ILS $150 per sample for 3 business days; Horizon $425 instead of $325 for 1 day; Janoshik and Analytical Formulations double the price; CheckPeptide adds 75% for 3 days and 300% for next day
Extra report copies, for example under another company name	$35–$100	Accumark $35; Freedom Diagnostics and Janoshik $50; ILS $100

Raw data deserves a close look. HPLC purity is a share of UV peak area, and only the chromatogram shows which peaks were counted. Some labs print a chromatogram on every report, and some sell it as an add-on, so ask before you order. Rush has one firm limit: no fee shortens a USP <71> sterility test, because the 14-day incubation is part of the method.

What a fuller panel costs on one peptide

Bills grow when endotoxin and a 14-day sterility test join the core test. Adding each lab’s list prices for the three tests on one peptide gives:

Lab	Core test	Endotoxin	Sterility (USP <71>)	Sum of list prices
Bioviridian	$150	$150	$200	$500
Accumark Labs	$250	$200	$250	$700
Vanguard Laboratory	$550 Gold package (core, endotoxin, bioburden, fentanyl screen, seal check)	Included	$150	$700
TrustPointe Analytics, semaglutide	$300	$300	$300	$900

These are our sums, not quotes, and the extra vials come on top. Some packages use a PCR screen in place of USP <71>. Accumark’s AccuShield panel (core test, endotoxin and a PCR sterility screen) is $578. Freedom Diagnostics’ purity and identity, net content, endotoxin and PCR screen add up to $550. A PCR screen detects microbial DNA from living or dead cells. It answers a different question from a culture that is watched for growth over 14 days, so check what “sterility” means in a package before you compare totals. Both safety tests are priced and compared in endotoxin and sterility test cost.

How group tests split the cost

Each member’s share is the lab bill divided by the number of members. ACS publishes an example in which a $200 lab fee costs $40 each for 5 buyers and $10 each for 20. BatchGuild’s example is a $400 test split 8 ways, at $50 each.

A group should usually test more than one vial, because vials from one batch can differ in content. At common published prices of $250 for a core test and $50 for each extra vial of the same batch, one core test plus two extra vials costs $350. For 10 members, that is $35 each before shipping. Adding endotoxin at $200 and USP <71> sterility at $250 raises the bill to $800, or $80 each. Vial-to-vial consistency explains what the extra vials show.

Groups face practical costs too. Janoshik’s online shop cannot split a payment, so groups arrange tests through its contact form. On Reddit, buyers often say the cost of testing alone is high, and some warn that a result from a lab your seller does not honour can mean paying for a second test. For collecting money, picking vials and sharing the report, follow how to run a peptide group test.

Free and low-cost testing services

Finnrick offers free testing. Its community tests cover identity, purity and quantity at no charge, Finnrick chooses the partner lab, and the result is published. Its Standard test costs $250, adds endotoxin and keeps the result private, with a target of about two weeks. Its Custom orders let you choose the lab, from $39 per sample at Krause Analytical, $69 at Ichor, $79 at BTLabs and $169 at PharmLabs. Keeping a Custom result unpublished costs $120 more.

Who pays shapes what you get. In a free test, Finnrick pays the lab and picks it, and the result becomes public. The trade-offs are set out in free peptide testing.

Peptide testing prices in the UK, Canada, Australia and Poland

Labs outside the US publish prices in their own currency, and their tests differ:

• UK: PeptideVerify lists HPLC purity alone at £325, purity with LC-MS identity at £430, and an express LC-MS test at £490, all including VAT.
• Canada: Peptide Test Canada lists CA$249 for HPLC purity and mass spectrometry identity, with raw HPLC data included, and CA$249 more for endotoxin.
• Australia: Ozcanium lists identity, purity and mg content at A$400 per sample before 10% GST, falling to A$325 each at 15 or more samples. Endotoxin is A$285 and its blind GLP-1 test A$540.
• Poland: Analiza Białek’s price page, as archived in April 2026, lists peptide analysis from 599 zł including VAT.

Sending a sample abroad adds shipping cost and days. The labs in each region are covered in the guides for Europe and the UK, Canada and Australia.

Prices change, so check the date

Chromate’s services page listed sterility at $180 in July 2024 and at $240 in September 2026. TrustPointe’s January 2025 price list put USP <71> sterility at $250, and its store listed $300 in September 2026. Its single-peptide prices, such as $200 for TB-500 and $300 for semaglutide, did not change over the same period. Any price list, this page included, is a snapshot. Check the lab’s current page and get the price in writing before you ship.

Safe savings and false savings

Some ways to pay less keep the evidence intact:

• Join or run a group test. The bill is split, and every member gets the same report.
• Test one batch once. If a group or a seller has already tested your batch, and the report can be checked on the lab’s own site, you may not need a second test of the same lot. Check that the lot number matches: see how to verify a peptide COA.
• Choose the tests that answer your question. Identity, purity and mg say what is in the vial. Endotoxin and sterility answer contamination questions. What a full peptide panel includes shows which tests you can skip.
• Send everything in one order. One parcel and one log-in cost less than two, and the sterility test starts on the same day as the rest.
• Skip rush when you can wait. Rush often doubles the price.
• Ask about volume tiers. Several labs publish them, and others quote them.

Other savings cost you the answer:

• Identity by retention time only. ICH Q6A says identification by a single retention time “is not regarded as being specific”. A similar peptide can elute at almost the same time. Mass spectrometry measures the mass itself.
• No raw data. Without the chromatogram and spectrum, you cannot check how a number was reached.
• Endotoxin as pass or fail. A number in EU per mg or per vial lets you compare it with any limit you choose. A pass against an unstated limit does not. See endotoxin testing.
• A “sterility” test that is not USP <71>. PCR screens and microbial counts answer other questions. Neither is a sterility test.
• A lab your seller or group does not accept. You may have to pay for a second test.

What HK Analytical quotes

HK Analytical has no published price list. Prices are quoted on request through the quote form, and group tests and batch testing for brands are quoted per sample. Our running costs are lower, and our quotes reflect that. The evidence does not change: every number comes with its raw data, in a signed record you can check.

One order can cover any mix, per sample, of identity (LC-MS), purity (HPLC), content per vial, blind GLP-1 identification, endotoxin (LAL), Sterility (USP <71>, 14 days), residual solvents, counter-ion (TFA, acetate), water content (Karl Fischer) and vial-to-vial consistency. Results within days of receipt. Sterility (USP <71>, 14 days) is the one test that takes 14 days, because the method incubates for 14 days. Each report carries our own photo of the vial as received, and anyone with the report ID and access key can check it on /verify. The example report shows the format.
