Supplier disclosure

Reviewed 22 October 2026 · How we research

Peptide Library is supported by Pristine Peptides (pristinepeptides.co.uk), a UK supplier of research peptides. Prices on our UK pages come from their catalogue, and our supplier cards link to their product pages.

We chose to reference them because they dispatch from the UK, publish batch-specific certificates of analysis and sell strictly for research use. We encourage readers to apply our supplier checklist to any seller — including this one.

The relationship does not affect what we write about efficacy, safety or evidence quality.
