Certificates of Analysis — per batch, independently verified

Reviewed July 2026 · Peptify UK (PEPTIFY LIMITED #17021295)

Every Peptify batch is tested by Janoshik Analytical, an independent laboratory, before sale. Each product page carries the downloadable Certificate of Analysis for the exact batch shipping now — the full HPLC chromatogram and purity reading, not a headline percentage. We never self-certify; a batch that misses the 99% specification is rejected at intake.

How to verify a Peptify COA

Open any product page, download the COA, and match the batch number printed on your vial to the certificate. Janoshik test numbers can be independently verified with the laboratory.
