About Onyx Peptides
A UK supplier of high-purity research peptides and reference materials, operated by Onyx Peptides Ltd.
Onyx Peptides was founded to give UK researchers a reliable, transparent source of research-grade peptides - independently tested, properly stored, and dispatched quickly. We focus on a curated range of the most widely studied compounds rather than an unmanageable catalogue, so we can stand behind the quality of everything we list.
Our principles
- Independent third-party testing on every batch
- Full batch traceability and certificates of analysis
- Honest labelling and clear research-use-only positioning
- Fast, discreet, fully tracked UK dispatch
