Research use only
Purity you can verify, not just claims
Pharmaceutical-grade research peptides for UK laboratories and qualified professionals. Every batch HPLC verified and released with its own certificate of analysis.
The science
Five mechanisms, one catalogue
Peptides are short amino acid chains — small enough to bind a specific receptor rather than fold into a shape that can't reach one. That specificity is why the research field exists. Hover a mechanism to find it on the strand.
Our standard
Verifiable, or it doesn't ship
Four commitments that decide what we will and won't release.
Every batch tested, not every product
Synthesis runs are not identical — different resin, different coupling efficiency, different impurity profile. A certificate that isn't tied to the batch in your hand tells you nothing about the batch in your hand.
HPLC purity and mass spec identity
Chromatography establishes how much of the vial is the compound. Mass spectrometry confirms it is the right compound. Purity without identity is only half an answer.
Certificates on request, always
Quote your batch code and we send the analysis for it. If a supplier can't produce one, that is itself the answer.
UK stock, UK dispatch
Lyophilised peptides tolerate ambient temperature for short transit windows. An order held in a customs facility for a fortnight is not a transit window — it is storage, in uncontrolled conditions.

The difference
Ask for the certificate first
Most of what separates a serious supplier from a reseller is a document they can either produce on request or they can't.
