A short note from the lab

CREW-LABS was founded on a simple principle: peptide research deserves uncompromising quality.

As one of UK’s newest peptide laboratories, we’ve built our reputation on precision, transparency, and reliability — the three things the category too often forgets.

/ 02 Our story

Built for the researchers who read the label.

CREW LABS emerged from a recognition that UK researchers needed a dependable domestic source for research-grade peptides. Our founders — with backgrounds in biochemistry and laboratory sciences — identified critical gaps in the market: inconsistent quality, unclear provenance, inadequate documentation.

We established our UK facility with a singular focus: synthesise peptides to the highest standards, verify every batch through independent testing, and provide complete transparency through detailed certificates of analysis.

/ 03 UK Manufacturing

UK-based. Batch-tested by world-renowned labs. Verified by COA. Trusted by researchers.

/ 04 How we work

Controlled conditions, documented from Synthesis to dispatch.

— 01 Synthesis

In-house, in UK.

Sourced from verified, approved manufacturing partners and independently third-party tested

02 Verification

HPLC on every batch.

Each batch undergoes independent third-party HPLC analysis by accredited UK laboratories. Verified purity data and complete batch traceability ship with every order — no exceptions, no abbreviations.

03 Compliance

Clearly labelled.

Every CREW LABS product is labelled “For Research Use Only” in compliance with MHRA guidelines. Our team of qualified scientists can provide technical support on documentation, storage and batch interpretation.

/ 05 The Standards

Three things we won’t move on.

— 01

Purity

A minimum of 99% purity, verified independently. Every vial ships with a third-party HPLC certificate showing the exact assay, the method used, and the accredited laboratory that ran it.

/ 04 Research Commitment:

In-vitro research, exclusively.

All CREW LABS products are developed and supplied strictly for in-vitro laboratory research. We do not provide guidance on human or animal use, and every product is clearly labelled “For Research Use Only” in compliance with MHRA guidelines.

Our team includes qualified scientists who understand the demands of modern research — and can provide technical support on documentation, storage, and batch interpretation.
