What Janoshik Analytical Is
Janoshik accepts samples directly from individual researchers and vendors, which is why it became the community standard: anyone can send a vial, and anyone can verify the resulting report. It is not an ISO 17025-accredited pharmaceutical lab (no ILAC/ČIA listing as of Oct 2026); it occupies the "community standard" tier in our lab directory, alongside Finnrick (free testing for about 15 common peptides, US residents only, with paid tiers) and above a vendor-issued COA.
HPLC Purity
Percentage of peptide content that is the target compound versus impurities and degradation products. Part of the standard report.
Reported as %
Quantity
Measured milligrams per vial versus the label claim. Part of the standard report. Underfilled vials are a more common problem than impure ones.
mg per vial
LC-MS Screening (add-on)
Identification of the compound by mass spectrometry. Not part of the standard HPLC report; a separate paid add-on (+$205). Ask for it, or rely on retention-time match against reference.
Optional
Endotoxin (LPS, EU/vial)
Bacterial endotoxin (LPS) content, ordered separately (+$180, separate vial required; standard reporting range 1–1000 EU/vial). Essential for anything that will be reconstituted and injected in a research setting.
EU per vial
Task Number + Unique Key
Each report has a task number (top-left) and a case-sensitive unique key (bottom), plus a QR that resolves to verify.janoshik.com. If the task number does not resolve, treat the PDF as unverified.

How to Read a Janoshik Report, Field by Field
| Field | What it means | What good looks like |
|---|---|---|
| Task number | Printed top-left. Unique identifier for this exact test; resolves on janoshik.com to the same values printed on the PDF. | Task number verifies; every field matches the online record. |
| Unique key | Printed at the bottom. Case-sensitive key entered with the task number in the Verify form. Not needed for tests the submitter made public. | Key accepted; watch for I vs l and 0 vs O when typing. |
| QR code | Resolves to verify.janoshik.com for this report. | Lands on a janoshik.com domain, not a vendor-hosted page or a look-alike domain. |
| Sample description | What the submitter said they sent, including label claim (e.g. "MOTS-c 10 mg"). A batch field appears only when the submitter supplied one. | Matches your product name, strength and, ideally, lot number. |
| Purity (HPLC) | Area-% of the main peak in the chromatogram. Part of the standard report. | ≥ 98% is our rule of thumb, not a Janoshik specification. 95–98% is acceptable for some long or difficult sequences; below 95% is a red flag. |
| Quantity | Measured mass of peptide in the vial. Part of the standard report. Example results line: MOTS-C 39.86 mg · Purity 99.723%. | Within roughly ±5% of the label claim (our rule of thumb, not a Janoshik specification). Public Janoshik MOTS-c results show e.g. 39.86 mg and 40.37 mg on 40 mg vials. A "10 mg" vial testing at 7 mg is underfilled even if purity is 99%. |
| Identity | Identity is not part of the standard HPLC report; LC-MS screening is an optional add-on. Ask for it, or rely on retention-time match against reference. | If LC-MS screening was ordered, the identified compound matches the label. If not, the report is silent on identity. |
| Endotoxin | LPS (endotoxin) content in EU per vial, if the test was ordered (separate vial required). | Reported, and low relative to the intended research dose. Absent on an injectable means the test was never run. |
| Testing ordered | Date the task was created. | Consistent with the other two dates. |
| Sample received | Date the sample arrived at the lab. | After the batch manufacture date. |
| Analysis conducted | Date the analysis was run. | Recent enough to reflect the product you hold; a report dated before the batch was made cannot describe it. |

How to Verify a Janoshik Report
Three routes, all on domains the lab controls. Type the address yourself rather than following a link hosted by the vendor.
01
janoshik.com Verify form
Go to janoshik.com and open Verify. Enter the task number (top-left of the report) and the unique key (bottom of the report). The key is case-sensitive and optional for public tests.
02
Scan the QR code
The QR on the report resolves to verify.janoshik.com. Confirm the domain, then compare task number, sample description, quantity and purity against the PDF.
03
Search public tests
If the submitter made the test public, find it on public.janoshik.com by compound or task number. No unique key needed.
If verification fails
- Typing errors in the key. I vs l and 0 vs O are the usual culprits; the key is case-sensitive.
- Vendor-hosted "verification". A link or page served by the seller proves nothing. Type janoshik.com yourself.
- Clone domains. Look-alikes such as janoshiklab.com are not the lab. Only janoshik.com and its subdomains (verify., public.) count.
- Still no match. If the task number does not resolve, or resolves to different values than the PDF, treat the document as unverified and ask for the original report.
What a Verified Report Proves — and Does Not
| Question | Answer | Why |
|---|---|---|
| Is the document authentic? | Yes | A task number and key that resolve on janoshik.com to the same values confirm the lab issued this report with these results. |
| Does it trace to my batch? | Only if the batch field was supplied and matches your vial | Janoshik prints a batch or lot only when the submitter provided one. Without it, the report describes a sample, not necessarily your lot. |
| Does it cover identity and endotoxin? | Only what was ordered | HPLC purity and quantity is the standard scope. HPLC ≠ identity ≠ endotoxin: LC-MS screening and endotoxin are separate add-ons and appear only if paid for. |
| Does it cover every vial? | No | One sample was tested. A good result is strong evidence about the batch, not a guarantee for each unit. |
This is why we register each Janoshik report against a specific LiveWell lot number at /verify: it closes the batch-traceability gap so the report you read is tied to the lot printed on the vial you hold.
Red Flags on a "Janoshik" Report
Task number does not resolve
The single most important check. If janoshik.com cannot find the task number, the PDF is not evidence of anything.
Fields differ from the online record
Edited PDFs usually change the purity or quantity number but leave the task number intact. Compare every value.
Wrong sample description
A report for a different strength, a different compound, or a generic description that could be any batch.
Report older than the batch
An analysis date before the product was made cannot describe it. Vendors sometimes reuse one good report for years.
Purity treated as identity
99% pure of what? The standard HPLC report does not identify the compound. Check whether LC-MS screening was ordered before accepting an identity claim.
"Janoshik tested" with no report
A claim is not a certificate. Ask for the task number and verify it yourself.
MOTS-c on a Janoshik Report
MOTS-c is a 16-amino-acid mitochondrial-derived peptide with a molecular weight of about 2175 Da (CAS 1627580-64-6). A 10 mg vial should measure close to 10 mg of peptide on the quantity line (our rule of thumb is within about ±5%, not a Janoshik specification), with HPLC purity high. Public MOTS-c tests already exist on public.janoshik.com; results such as 39.86 mg and 40.37 mg on 40 mg vials show what a well-filled lot looks like. Our own MOTS-C 10 mg lot WO-0059 is in the queue and its result will be published here, in the lots table below, and at /verify. Read the MOTS-c compound guide for background on the peptide itself.
Lots We Have Submitted to Janoshik
Rather than only describing independent testing, we are doing it. The current round sends three lots to Janoshik: the MOTS-C 10 mg vial and the two oral tablet SKUs our first partners will carry. Results are published here, in the lab-tested lots index, and in the public lot registry behind /verify as soon as the reports are back.
| Lot / work order | Product | Lab | Panel | Status | Notes | Source |
|---|---|---|---|---|---|---|
WO-0059 |
MOTS-C 10 mg Lyophilized vial |
Janoshik Analytical | HPLC purity + quantity · Endotoxin (LPS, EU/vial) | In progress — awaiting Janoshik report | Flagship injectable SKU. See the MOTS-c compound page. | Get it at LiveWell → |
WO-0025 |
Oral tablet SKU #1 Tablet |
Janoshik Analytical | HPLC purity + quantity (potency vs label) | In progress — awaiting Janoshik report | First tablet SKU for partner intake. Product name added when the lot is registered. | Get it at LiveWell → |
TBD |
Oral tablet SKU #2 Tablet |
Janoshik Analytical | HPLC purity + quantity (potency vs label) | Work order pending | Second tablet SKU for partner intake. Work order pending. | Get it at LiveWell → |
Status is checked live against the public LiveWell lot registry (the same source behind Batch Lookup and /verify). A lot shows "COA published" the moment its independent report is registered.
Janoshik vs. Vendor COA vs. Finnrick
| Source | Who pays / submits | Conflict of interest | Typical scope | Verifiable? |
|---|---|---|---|---|
| Vendor-issued COA | The seller | Yes — same entity that profits from the sale | Often purity only; sometimes supplier template | Rarely |
| Janoshik Analytical | Anyone (vendor or researcher), paid per sample | None in the sale | HPLC purity and quantity (mg per vial) as standard; LC-MS screening, endotoxin and sterility as paid add-ons | Yes — task number + unique key on janoshik.com |
| Finnrick Analytics | Free testing for ~15 common peptides, US residents only, with paid tiers (standard test ~$250) | None in the sale | Purity and dosage; routes samples to partner labs including Janoshik | Yes — published results |

Frequently Asked Questions
What is Janoshik Analytical?
+
Janoshik Analytical is an independent analytical laboratory based in the Czech Republic that tests research peptides and related compounds. Its standard peptide test reports HPLC purity and quantity (mg per vial); LC-MS screening (identification), endotoxin and sterility are separate paid add-ons. It is widely described as the most referenced third-party lab in the peptide research community, and each report carries a task number and unique key that can be verified on Janoshik's own site.
Is Janoshik legit?
+
Janoshik Analytical is a real, long-running laboratory that accepts samples from anyone and publishes a verification tool for its own reports, which is why the research community treats it as the default reference lab. It is not ISO 17025-accredited (no ILAC/ČIA listing as of Oct 2026), so its reports are best read as credible independent evidence rather than as regulatory-grade certificates. The practical test of legitimacy is whether a given report verifies on janoshik.com, not whether the lab's name appears on a PDF.
Is Janoshik ISO 17025 accredited?
+
No. We found no ILAC or ČIA (Czech Accreditation Institute) listing for Janoshik Analytical as of October 2026. That does not make its results wrong, but it means there is no external audit of its methods. If you need an accredited result, see the ISO 17025 and GMP options in our Testing Labs directory.
How much does a Janoshik test cost?
+
As listed on janoshik.com on 2026-10-06: MOTS-c analysis (HPLC purity and quantity) $450; endotoxin analysis +$180 (separate vial required); sterility +$290; LC-MS screening +$205 (identification only); rush service +100%. A GLP-1 blind test starts from about $360. Prices vary by compound and change over time, so confirm on the lab's pricelist before ordering.
How long does Janoshik take?
+
About 7 business days for a standard peptide test (HPLC purity and quantity) after the sample arrives. Sterility testing takes roughly 14 days because of incubation. Rush service is available at +100% of the test price. Shipping time to the Czech Republic is additional.
How do I read a Janoshik report?
+
Check five things in order: (1) the task number and unique key verify on janoshik.com and the online record matches the PDF, (2) the sample description matches your product and, ideally, your lot, (3) HPLC purity is high (we use about 98% as a rule of thumb; it is not a Janoshik specification), (4) the measured quantity is close to the label claim (for example 9.6–10.4 mg on a 10 mg vial; public Janoshik MOTS-c results show e.g. 39.86 mg and 40.37 mg on 40 mg vials), and (5) for injectables, endotoxin is reported and low. A results line reads like 'MOTS-C 39.86 mg · Purity 99.723%'. Identity is not part of the standard HPLC report; LC-MS screening is an optional add-on.
Where is the unique key on a Janoshik COA?
+
The task number is printed at the top-left of the report. The unique key is printed at the bottom of the report and is case-sensitive. The QR code on the report resolves to verify.janoshik.com. For tests the submitter made public, the unique key is not required; you can find the report by task number or on public.janoshik.com.
What if verification fails?
+
First re-type the key: I and l, and 0 and O, are the usual culprits, and the key is case-sensitive. Make sure you are on janoshik.com or verify.janoshik.com that you typed yourself, not a link hosted by the vendor, and not a look-alike domain (janoshiklab.com is not the lab). If the task number still does not resolve, or resolves to different values than the PDF, treat the document as unverified and ask the vendor for the original report.
Does Janoshik confirm identity by mass spec?
+
Not in the standard test. The standard peptide report gives HPLC purity and quantity (mg per vial). LC-MS screening is a separate paid add-on (+$205) that identifies the compound. If identity matters to you, ask the submitter whether LC-MS screening was ordered, or rely on the HPLC retention-time match against a reference standard.
Can I send my own vial to Janoshik?
+
Yes. Anyone can order a test: individual researchers and vendors use the same ordering process. You create a task on janoshik.com, ship the sealed sample to the lab in the Czech Republic, and receive the report under your task number. Endotoxin testing requires a separate vial.
What is the difference between a Janoshik COA and a vendor COA?
+
A vendor COA is issued by the company that made or sells the compound, so it is self-reported. A Janoshik report is produced by a lab with no stake in the sale, on a sample the submitter sent in. Independent testing does not guarantee every vial in a batch, but it removes the conflict of interest that a vendor-issued document carries.
Does a Janoshik purity result tell me the vial is safe?
+
No. Purity only says what fraction of the peptide content is the target compound. It does not confirm identity, endotoxin, sterility, heavy metals or residual solvents unless those tests were ordered separately. For injectable research compounds, HPLC purity and quantity plus endotoxin is the minimum useful panel; add LC-MS screening if identity is in question.
How can I tell if a Janoshik report has been altered?
+
Verify the task number and unique key on janoshik.com and compare every field, not just the headline purity. Mismatched fonts, a sample description that does not match the product, an analysis date before the batch was made, or a task number that resolves to a different compound are all signs the PDF was edited. Our COA Verifier checklist walks through these checks.
Which lots has Path to Peptides submitted to Janoshik?
+
Three lots are in the current round: MOTS-C 10 mg (work order WO-0059) and two oral tablet SKUs (WO-0025 and a second work order pending). Status on this page updates automatically when a report is registered in the public lot registry; until then each lot shows as awaiting its report.
