Janoshik Analytical: What It Tests and How to Verify a Report

What Janoshik Analytical is

Janoshik Analytical runs chemical analysis for customers who post in a sample. Its about page calls it "an independent testing laboratory offering reliable and verifiable analytical services" and lists peptides alongside other compound groups. The same page names three people: an owner and CEO, a CSO, and a managing director and CFO.

The pages we read do not give a street address for the lab and do not name an accreditation. Its prices are shown in US dollars and Czech koruna. Anyone can order: the site says it accepts samples "from all over the world" and takes cards and crypto.

What it tests on a peptide sample

Each peptide has its own listing. The BPC-157 listing describes the test as "ID, amount and purity analysis" and gives these parameters:

• Testing method: HPLC
• Result format: mg per vial and peptide purity (an alternative m/m purity format is free)
• Sample needed: one whole unopened vial, or 30 mg of raw powder in a sealed glass vial

So a standard Janoshik peptide report answers three questions: is the compound present, how much is in the vial, and how pure it is. Contaminant tests are not included unless you add them.

Listed prices and turnaround

Prices below are copied from Janoshik's own listings on Nov 6, 2026. They change, so check the site before ordering.

• BPC-157 analysis: $215
• GHK (or GHK-Cu) analysis: $290
• Many less common peptides: $450 each
• Blind peptide screening (unknown sample): $600

Add-ons on the BPC-157 listing:

Turnaround is shown as a live snapshot on the homepage. On Nov 6, 2026 it read 36 hours average lab turnaround and 2 hours average for rush testing, both from sample receipt.

How Janoshik verification works

Every report ends with a line telling the reader to verify the test at janoshik.com with a unique key. The verification page asks for two things: the task number and the unique key. The report also carries a QR code that leads to the lab's copy.

Janoshik also runs a public results list at public.janoshik.com. Its contact form has a "Public Report Request" option. Each entry shows the task number, the test, who submitted it and who made the product. The list carries a notice that Janoshik does not endorse or have any affiliation with the companies listed.

A public Janoshik report, field by field

We opened public task #125225, a BPC-157 and TB-500 blend submitted by a vendor. The report has these fields:

Which vendors link Janoshik results

We checked the testing pages of the ten vendors on our comparison on Nov 6, 2026.

• Swiss Chems links Janoshik verify pages from its product page lab reports, for example the BPC-157 arginine salt batch 2606-ED-BP. Other batches on the same page link to Freedom Diagnostics.
• PSPeptides does not mention Janoshik on its certifications page. Its peptide reports come from North American Diagnostics and can be checked on that lab's portal instead.
• None of the other vendors we checked named Janoshik on the pages we opened. One site refused our request.

The full table is on third party tested peptides.

Limits of any single report

• A report covers the vial tested, not every vial in a batch.
• Vendor-submitted samples are picked by the vendor.
• Add-on tests such as endotoxin and sterility are optional, so check which ones were run.
• A public listing can be old. Compare the analysis date with the batch you are looking at.
