Quality & testing

Every batch, independently verified.

We test what we ship. Each lot is analysed by a third-party laboratory and accompanied by a batch-specific Certificate of Analysis.

1 · HPLC analysis

High-performance liquid chromatography confirms purity to ≥99%.

2 · Mass spectrometry

Molecular weight is validated to confirm compound identity.

3 · Certificate of Analysis

A signed COA ships with every order and is available on request.

What's on a COA?

Storage & handling

Lyophilized peptides are stable at −20 °C, protected from light. Once reconstituted with bacteriostatic water, store refrigerated and use within the documented window for your study design.
