Janoshik is the name printed in the laboratory position on 23 documents in the register, published by Atomik Labz, Evolve Peptides, Nexaph and Paramount Peptides. Every one of them carries a lot identifier; every one is dated, the earliest 2024-10-21 and the latest 2026-06-01; 7 print a purity figure, between 99.179% and 99.862%. No method is printed in a form we could record. The documents are image and web page, covering 8 distinct peptides.
The desk's laboratory explainer notes that this name is spelled three ways across supplier sites (Janoshik, Janoshik Analytical, Janoshik Laboratory), that the laboratory states on its own site that it operates from the Czech Republic, and that it publishes a report-lookup function; documents printed with the longer spelling are filed on a separate page because the register keeps each spelling as printed.
A laboratory name on a certificate is the supplier's statement that this laboratory produced the report. The desk records it as printed and does not merge spellings, rank laboratories or confirm the report with the laboratory on a reader's behalf; what a name does make possible is the question, which is set out in How to verify a peptide COA with the lab and Peptide testing labs explained. A purity figure in the table is the laboratory speaking about one lot on one date, not a score.
Also in the register under another spelling: Janoshik Analytical (10 documents). Each spelling is kept as the documents print it.
