Lab Results & Certificates of Analysis
Every Peptides & You research peptide is sent to Janoshik Analytical, an independent third-party laboratory, for identity and purity testing. We publish the full Certificate of Analysis (COA) for each batch — and every result can be verified directly with the lab. No guesswork, no marketing claims: just the numbers.
Verified results
All testing by Janoshik Analytical, an independent third-party lab.
* Purity % cannot be measured in blends — impurities of the mixed peptides obscure each other, so blends are verified for identity and content instead.
How to verify any result
Each certificate carries a unique key. Enter it at janoshik.com/verify to confirm the report directly with the lab — not with us.
Research use only
All products are supplied for laboratory and research use only — not for human or veterinary consumption. These statements have not been evaluated by the U.S. FDA or the Philippine FDA.
