Janoshik alternatives: labs that test the same peptides, compared by method, turnaround and report checks

Why buyers look for a Janoshik alternative

Janoshik is the lab many group testers start with, and many buyers treat its results as the reference. People still look for a Janoshik alternative, for one of five practical reasons:

• A test or report format it does not list. Janoshik’s standard peptide method is HPLC, which reports mg per vial and purity. Its sterility add-on is a microbial count (TAMC and TYMC) reported as pass or fail, which is a different method from the USP <71> sterility test. Some buyers want mass-spectrometry identity printed on every report.
• Turnaround. Janoshik publishes an average of 7 business days for peptide tests, and 14 days for sterility. Rush testing can be arranged before the sample arrives.
• Region. Janoshik is based in the Czech Republic. Buyers in the US, Canada or Australia may prefer a lab inside their own postal system.
• Verification needs. A vendor or a group may ask for results from a named lab.
• A second opinion. Groups send one batch to two labs to compare. Labs often disagree, as our guide on why labs disagree explains.

What Janoshik offers, as the baseline

Any alternative should be measured against what Janoshik already does well:

• Breadth. About 80 peptide tests, plus steroids, SARMs and other compounds. HGH can be tested for amount, purity, and dimer and larger proteins.
• A blind GLP-1 test. It finds which of semaglutide, tirzepatide or retatrutide is in the vial, or a mixture, without being told the label.
• Add-ons per sample. Endotoxin (LAL), sterility (TAMC and TYMC), TFA, raw data, a fentanyl check, variance testing across vials, pH, CHNS and an LC-MS contamination screen.
• Report checks. Each report has a task number, a 12-character key and a QR code. The verify page shows a watermarked photo of the vial.
• Ordering. Card, bank transfer and crypto. Each test page shows a price; our price comparison lists them by lab. Group tests are arranged through the contact form.

Our Janoshik review covers ordering and report checks step by step.

Janoshik alternatives compared: Vanguard, Chromate, MZ Biolabs, Testides and more

The table lists labs that test the same kinds of peptides, with Janoshik first as the baseline. “Identity” is the method each lab names for its standard test. Turnaround is what the lab publishes, not a measured figure.

Lab	Based in	Identity on the standard test	Endotoxin / sterility	Published turnaround	How a report is checked
Janoshik (baseline)	Czech Republic	HPLC; the report names the peptide	LAL endotoxin; TAMC and TYMC count, pass or fail	Average 7 business days; sterility 14 days	Task number and 12-character key; QR code
Freedom Diagnostics	Franklin, TN, US	LC-MS identity, paired with HPLC purity	LAL endotoxin; PCR microbial screen	Average 1–3 business days	Public lookup by company name or code
Vanguard Laboratory	Olympia, WA, US	HPLC-UV retention time against a reference standard	Endotoxin; USP <71> 14-day sterility as an option	Confirmed per order; sterility 14 days	Report hub, for reports the client makes public
Chromate	Hudson, NH, US	HPLC by default	Kinetic chromogenic LAL; sterility by membrane filtration	Not stated	Job number and access code
MZ Biolabs	Tucson, AZ, US	Accurate mass by QTOF: expected and measured mass	Endotoxin (USP <85>)	Not published	QR code on 2026 reports; no lookup page on the lab’s site
TrustPointe Analytics	Dorr, MI, US	HPLC-UV retention time and UV spectrum	USP <85> endotoxin; USP <71> sterility	3–5 business days	QR code or key on the lab’s LIMS
Krause Analytical	Austin, TX, US	HPLC-UV and HPLC-MS	USP <85> endotoxin; USP <71> sterility as add-ons	Not published	Upload form; the lab replies by email
Analiza Białek	Wrocław, Poland	HPLC-DAD against reference standards	None listed	5–7 working days stated	Order number and password
PeptideVerify	London, UK	HPLC, with LC-MS identity in the full option, at a UK partner lab	Endotoxin (LAL); check availability before sending	5–7 business days; express 3–5	QR code and reference number
Testides	Ontario, Canada	HPLC-DAD retention time and UV match; MS when ordered	Endotoxin (USP <85>)	Results within 10 days or money back	Report number lookup on its verify page
SideChain Analytics	Mississauga, Canada	HPLC-MS/MS (MRM)	Kinetic chromogenic LAL; no sterility	5–7 business days	QR code, or report number, sample ID and code
Ozcanium Analytics	Sydney, Australia	LC-MS/MS (MRM) with UPLC-UV purity	Endotoxin; no sterility	4–10 business days typical	Verification code
HK Analytical	Mail-in	LC-MS mass match	Endotoxin (LAL); Sterility (USP <71>, 14 days)	Results within days of receipt; sterility 14 days	Signed record, private link, /verify

Two notes on the table. Testides describes itself as an analytical data service: a laboratory performs the measurement, and Testides coordinates the work and reviews the data. PeptideVerify sends samples to a UK partner laboratory. Vanguard holds A2LA ISO/IEC 17025 accreditation (certificate 6377.01). Its published scope does not cover peptide purity, identity, endotoxin or sterility, and Vanguard says on its site that accreditation applies only to the methods in its scope.

Choosing an alternative by what you need

Mass-spectrometry identity on the report

Retention time alone can match a similar peptide. If you need the mass on paper, MZ Biolabs prints expected and measured mass, Freedom prints a spectrum image, and SideChain and Ozcanium use triple-quadrupole MS. Our page on LC-MS identity shows what a mass match looks like.

A 14-day sterility test

Vanguard, Krause and TrustPointe list USP <71>. Chromate’s page describes membrane filtration and incubation per USP <71>, but a Chromate report we read cited USP <1223>, the chapter on alternative methods. Janoshik’s TAMC and TYMC test is a microbial count, and Freedom’s PCR test screens for microbial DNA. Neither is the USP <71> method. Our guide to sterility testing explains the difference.

A blind GLP-1 test

Janoshik’s blind test covers semaglutide, tirzepatide and retatrutide. Ozcanium sells a blind GLP-1 test in Australia. See blind GLP-1 identification for how these tests work.

A lab in your region

In Europe, Analiza Białek works in Polish, and PeptideVerify serves the UK. In Canada, SideChain and Testides take samples. In Australia, Ozcanium serves local buyers. Our guides to peptide testing in Europe, Canada and Australia cover each region in more depth.

A portal for group tests

Janoshik arranges group tests through its contact form, because its shop cannot split a payment. Peptide Test gives each group a Group Test ID, lets members split the payment, and shows payment and shipping status in its portal. Our guide on how to run a peptide group test covers the steps.

A result your vendor will accept

Check the vendor’s refund terms before you pick a lab. Our guide on which lab results vendors accept explains why this matters. If a group wants a cross-check, send vials from the same batch to two labs on the same day and ask both for the basis of the mg result.

Finnrick vs Janoshik: two different services

Finnrick is not a lab. It collects samples, sends them to partner labs and publishes vendor pass rates. Finnrick’s lab page lists about 200 published Janoshik results, dated 14 April to 9 September 2025, and no Janoshik tests can be ordered there now. If you want Janoshik, order directly. Finnrick also offers free community testing with published results, but not at Janoshik. Our guides to free peptide testing and Finnrick alternatives compare the routes.

What HK Analytical offers

We run 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. You can order any mix per sample in one order, and see the full test list. 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.

Every number comes with its raw data. The report is a signed record with a private link, and it can be checked on /verify. It shows our own photo of the vial as received and states how the client is related to HK Analytical. We do not hold ISO/IEC 17025 accreditation. Quotes are on request, and organisers can arrange group tests.
