How to verify your research peptides
Public Certificate of Analysis
Every product page links directly to the Janoshik COA. You’ll see the tested purity, method (HPLC), and the exact batch number — no redactions, no gating.
Match lot number on vial
Each vial label includes a unique lot number. Compare it with the COA to confirm you received the exact batch that was tested. Tamper-evident seals protect integrity.
99%+ purity guarantee
If a batch falls below 99% purity, we flag it and adjust pricing or remove it. Our average is 99.2% across all compounds. Trust the data, not claims.
