About Peptide Library

Reviewed 22 October 2026 · How we research

Peptide Library is a reference library for people researching peptides in the UK. Search results for peptides are crowded with sellers' product pages and forum threads; we wanted one place that explains each compound plainly, cites the studies, and is honest about how thin the evidence often is.

What we cover

  • What each peptide is, where it came from and how it is thought to work.
  • What published research has and has not shown, with references.
  • The doses used in those studies, and the arithmetic of reconstitution.
  • UK legal and regulatory status.
  • How to judge purity and supplier quality.

What we do not do

  • We do not give personal medical advice or recommend doses for human use.
  • We do not sell anything.
  • We do not publish testimonials or before/after claims.

Funding

The library is supported by Pristine Peptides, the UK supplier we reference for prices. See our disclosure and editorial policy.
