Built by scientists, for science.

REP Research Lab was founded in 2017 to bring pharmaceutical-grade rigor to the research peptide market — eliminating the guesswork around purity, identity, and provenance.

What drives us

A mission rooted in reproducibility.

Our mission

Accelerate peptide research by providing transparent, traceable, and reproducible reagents. Every product we ship is accompanied by a batch-specific certificate of analysis from an independent laboratory — never an in-house assay alone.

Our facility

A 12,000 sq ft ISO-9001 cleanroom in Zurich houses our SPPS reactors, prep-HPLC purification lines, lyophilizers, and analytical instruments — including HPLC-MS, FTIR, and Karl Fischer titrators.

Where every batch begins.

Purpose-built for solid-phase peptide synthesis, with environmental controls validated quarterly by an external auditor.

“Every batch we've sourced from REP Research Lab has matched the COA within decimals. That kind of reproducibility is rare, and it's why they're our default supplier.”
