Our story
UK-based. Independent. Built around one question: can the customer verify this themselves?
SHOP NOW →The UK research peptide market was — and largely still is — built on unverifiable claims. Suppliers producing their own certificates of analysis. PDFs with no independent source. No way to know if what was in the vial matched what was on the label.
We built Zenic Labs around one non-negotiable: every compound independently tested by Janoshik Analytical before it reaches a customer. Not occasionally. Not for selected batches. Every time, without exception.
Janoshik publish results publicly. An order number on our CoA can be cross-referenced directly on their website — with no involvement from us. That is the only form of verification that cannot be manipulated.
To be the supplier the UK research community can point to as the reference standard. Not the cheapest. Not the loudest. The one you can verify.
What we stand for
We don't ask you to take our word for anything. Every result is independently verifiable at janoshik.com by order number — by anyone, at any time. If you can't check it yourself, it doesn't count.
Vague language like 'high purity' or 'third-party tested' means nothing without evidence. We publish exact figures, named laboratories, and individual batch order numbers. The detail is the point.
We tell you what our products are — lyophilised research compounds for in-vitro use — and what they are not. We don't dress up regulatory language or hide disclaimers. Clarity is a form of respect.
Testing every batch independently costs more and takes longer than self-certifying. We do it anyway. The moment we cut that corner, we become the problem we set out to solve.

Every product page links directly to its Janoshik CoA. Download it, verify the order number, then decide.
