About Black & White Peptides Ltd

Who We Are

Black & White Peptides Ltd is a UK-registered limited company (Companies House number 16876162) supplying research-grade peptides and small-molecule compounds to laboratories, academic groups and distributors across the UK and Europe.

We are not a compounding pharmacy. We are not a telehealth provider. We are a specialist research-reagent supplier - every product we ship is supplied strictly for in-vitro laboratory research use only, and is not a pharmaceutical, medicine, dietary supplement or consumer product.

Why Researchers Choose Us

• Independent HPLC verification. Compounds are tested by Janoshik Analytical, a specialist third-party peptide analysis lab. Where a Janoshik report has been issued for the current batch it is supplied with the order and carries a unique verification key that can be authenticated against Janoshik's own records; otherwise the verification record is published on our Purity page.
• Consistency across batches. We work with the same synthesis partners across repeat orders so our HPLC traces stay consistent lot-to-lot - important if you are running longitudinal research.
• Clear compound data. Every compound in our catalogue has its own reference page with sequence, receptor targets, stability profile and a summary of how it is characterised in the peer-reviewed literature.
• UK-based and UK-dispatched. Orders are dispatched from a UK address with Royal Mail Tracked 24 as standard. Next-day delivery available.
• Research-use-only supply. Every order requires a research-use confirmation at checkout. We do not provide dosing guidance, administration instructions, or any content relating to human or veterinary use.

What We Supply

Synthetic peptides and small-molecule research compounds in defined amino-acid sequences, supplied as lyophilised powder in sealed vials or as pre-reconstituted multi-dose cartridges. Each vial is labelled with compound name, mass, batch identifier and corresponding Janoshik lab report reference.

Our catalogue covers seven research areas: Metabolic Research, GHRH / Secretagogue Research, Regenerative Research, Longevity Research, Neuropeptide Research, Melanocortin Research and Cofactor Research.
