Janoshik verification
Use the task number and unique key printed on a certificate to check the laboratory's returned report, then compare every field with the document you were given.
Some peptide testing records in this independent index name Janoshik Analytical as the laboratory. The Peptide App groups those records so you can inspect dates, lots, reported results, vendors, and peptide coverage. The Peptide App has no affiliation with the laboratory.
Use the task number and unique key printed on the certificate in Janoshik's official verification system, then compare the returned report with the document field by field. A matching report does not establish the retail vial's chain of custody.
No. A matching laboratory report can support what was measured for a submitted sample, but it does not by itself prove vendor identity, retail-vial chain of custody, sterility, endotoxin status, or suitability for use.
Current evidence
This table shows the newest 24 current records. Printed test dates run from January 2024 through August 2026.
Peptide, laboratory, date, lot, and purity fields are transcribed from the certificate. “On file” describes our records and carries no product-quality or safety rating.
Coverage by molecule
These are document counts. They do not rank peptides, vendors, or laboratories.
Vendor coverage
Open a vendor to see every current peptide certificate in this lab group and compare its full COA coverage.
Name handling
The exact laboratory spelling remains visible on each certificate row.

We group these spellings under “Janoshik Analytical” only to calculate totals. Grouping does not authenticate a document or judge the laboratory.

Evidence limits
A laboratory name is one field on a certificate, not a quality verdict.
Use the compound, test date, lot number, vendor, and reported result together. A laboratory attribution alone does not prove that a file is authentic or that the tested sample came from a particular retail vial.
A reported HPLC purity value describes the portion measured by that assay. It does not, by itself, establish identity, vial content, sterility, endotoxin status, chain of custody, or overall product quality.
Certificates carrying a Janoshik task number and unique key can be checked in the laboratory's own system. Compare the returned report with the document field by field; a match still does not establish vendor chain of custody.
