In short
Janoshik Analytical is an independent analytical lab (consumer and vendor clients). On its own site it lists hplc purity and amount, mass spectrometry identity, blind screening tests (e.g. glp-1 identification) and more. To verify one of its reports: task number + unique key on janoshik.co/verify; reports carry a QR code. This profile describes what the lab publishes; it is not a rating.
What does Janoshik Analytical test for?
as listed by the lab| Test listed | What it measures | Explainer |
|---|---|---|
| HPLC purity and amount | Relative purity: main peak share of UV-detected material | Read |
| Mass spectrometry identity | Whether the main component has the expected molecular mass (identity) | Read |
| Blind screening tests (e.g. GLP-1 identification) | As described on the lab's own site | — |
| Protein analysis (amount, purity, dimers) for hGH | Relative purity: main peak share of UV-detected material | Read |
Janoshik is the lab name that appears most often on certificates shared in the research-peptide market. This profile describes what the lab says it does and how to check its reports. It is not a rating.
What it says it does
Its site describes “harm reduction chemical analysis” for steroids, peptides and pharmaceutical compounds, with clients ordering tests online and posting samples. The catalog listed on October 19, 2026 included a “Common GLP-1 peptide blind test (Semaglutide, Tirzepatide and Retatrutide)” at $360, and a human growth hormone “amount, purity and dimer and higher molecular weight proteins analysis” at $500. Prices are as listed on that date and may change.
Process, as described by the lab
- Select a test.
- Send the sample using shipping instructions provided after ordering.
- Lab analysis.
- Digital report by email and in the client’s account.
Is Janoshik legit?
Janoshik is an operating lab with a public catalog, a public results page and a report verification system, so a Janoshik report can be checked rather than taken on trust. Amino Wire does not rate labs or vouch for any lab’s accuracy. What you can check:
- Is the report real? Enter the task number and unique key on janoshik.co/verify and compare every field with the PDF you were given.
- What was tested? A report covers the tests listed on it. HPLC purity and mass-spec identity results say nothing about endotoxin or sterility unless those tests appear on the report.
- Which sample? A report describes the one sample that was sent, on the date tested. It does not show that later batches, or the vial you receive, match.
Verifying a report
Janoshik’s verification page takes the task number and unique key printed on a report. Check that the returned record matches the document exactly (7-step COA check).
Public results
The lab maintains a public results page. Clients can choose to make a result public. A result’s presence there is a record of one test, not an endorsement of the product or seller.

Janoshik Analytical: common questions
How do I verify a Janoshik Analytical report?
Task number + unique key on janoshik.co/verify; reports carry a QR code. Always use the lab's own website (janoshik.co), not a link supplied by a seller, and check that the lot number and compound match your vial.
What tests does Janoshik Analytical list?
As of October 19, 2026, its site lists: HPLC purity and amount; Mass spectrometry identity; Blind screening tests (e.g. GLP-1 identification); Protein analysis (amount, purity, dimers) for hGH. Each test must be ordered separately, so a given report may include only some of them.
