Document-first research peptide supplier

Repilabs is a research-focused supplier of peptides and reference compounds. We exist to give laboratories a dependable source of well-characterized material — without the noise, claims, and marketing that have no place in a research workflow.

We work with a small, vetted network of manufacturing partners and independent analytical laboratories. Keeping that network narrow is deliberate: it lets us know exactly where our material comes from and how each lot was tested.

Every production lot is analyzed by independent laboratories using reversed-phase HPLC for purity and LC-MS for identity confirmation. Peptides are released at ≥99% purity (HPLC) and supplied lyophilized for stability in transit and storage.

A lot-specific Certificate of Analysis is available on request for any catalog item, and each vial is lot-numbered so results can always be traced back to the batch in front of you.

Our catalog is intentionally focused on a core set of research peptides and supporting reagents. We do not carry a sprawling range; we carry compounds we can characterize and document consistently. If you need something outside the listed catalog, we can often source additional research compounds on request.

All materials supplied by Repilabs are intended strictly for in-vitro laboratory research and development. They are not drugs, food, cosmetics, or medical devices, and are not for human or veterinary use, consumption, or any in-vivo, diagnostic, or therapeutic application.

We sell to businesses and research entities only. By purchasing, the buyer accepts responsibility for the safe, lawful handling, use, and disposal of all materials in accordance with applicable regulations in their jurisdiction.
