Zenic Labs — The only UK peptide supplier whose lab results you can verify yourself

Every test is conducted by Janoshik Analytical. Results are searchable by order number at janoshik.com — by anyone, at any time. They cannot be forged.

Public CoAs

Full PDFs linked on every product page. No login, no barrier. Download the report before you spend a penny.

Per-Batch Testing

Every production run is tested individually. Your batch number is tied to its own certificate of analysis.

Guaranteed Quality

If your order arrives damaged or the seal is compromised, we replace it the same day. No questions, no delays.

Know what to ask

Most suppliers test
their own products.

Ask any supplier one question: can I independently verify this result on the laboratory's own website — without contacting you at all? If they can't answer yes, you don't have independent verification.

HOW TO VERIFY IN 30 SECONDS

Find the lot number on your CoA → go to janoshik.com → search the order number → see the result directly on their platform. No supplier involvement required.
