Research Peptides for Sale in the UK
UK Peptide Lab supplies research peptides for laboratory use from UK stock. Peptides are supplied as lyophilised powder in sealed glass vials, priced per vial, with the certificate of analysis for each batch published on the product page wherever one has been issued.
The batch number printed on each vial matches its certificate. Check for this wherever you buy peptides online: a certificate without a batch number, or one reused across batches, tells you nothing about the vial you receive.

Minimum specification. Each page shows the figure from that batch's certificate, not a blanket claim.

BrowseFrequently Asked Questions
Where can I buy peptides UK researchers can verify?
From a supplier that publishes a batch-specific certificate you can match to the vial. UK Peptide Lab ships from the UK with an HPLC and mass-spectrometry certificate on every product page, naming the testing laboratory and its report number, so it can be checked against the batch number printed on the vial. Orders placed before 3pm on a working day are dispatched the same day by Royal Mail Tracked 24, and UK delivery is free over £69.
What purity are the peptides sold here?
The minimum specification is 98% by HPLC, and most compounds test above 99%. Each product page shows the figure from that batch's own certificate, so it varies between compounds and between batches.
Are research peptides legal to buy in the UK?
Yes, for in-vitro laboratory research. They are not licensed medicines and are not sold for human or veterinary use. Buyers must be 18 or over and accept research-use-only terms at checkout. Our guide to UK peptide law.
How should peptides be stored on arrival?
Store lyophilised vials at -20°C, dry and away from light. Once reconstituted with bacteriostatic water, keep them at 2-8°C and use within about four weeks. Reconstitution guide.
