Research Peptides

The full research peptide catalog

25 of 25 products · 99%+ HPLC purity, third-party verified · Same-day UK dispatch

Every compound listed here ships as a lyophilised vial, independently HPLC-verified to ≥99% purity, with a Certificate of Analysis on record for the batch you receive. We split the catalog into three groups — single-compound research peptides, pre-mixed research blends (for labs running comparative or combination protocols), and GH secretagogues — so you can go straight to the class of compound your work requires. Every listing links out to open-access PubChem/PubMed data and, where available, our own research-hub primer on that compound. Supplied for laboratory research use only; not for human or animal consumption.

High-quality research peptides, shipped from the UK

SupplyPeptides supplies UK-based laboratories and qualified researchers with independently verified research peptides. We exist to remove the guesswork from sourcing — every batch is HPLC-tested, documented and dispatched cold-chain.

Verified purity — 99%+ HPLC

Every batch is independently tested by an accredited third-party laboratory before release. HPLC confirms purity, LC-MS confirms identity against a certified reference standard, and the results are published as a per-batch Certificate of Analysis.

Quality assured documentation

Every product on this page links to its own HPLC and LC-MS report, so researchers can check identity and purity for the material they receive before it reaches the bench. Browse the Certificates of Analysis library.

Catalogue compounds

Our catalogue spans GLP-1 and GIP research peptides, healing and recovery compounds, growth hormone secretagogues, and nasal spray formats — all supplied as lyophilised powder unless otherwise stated.

Handling & storage

Materials are supplied lyophilised and should be stored at −20°C on arrival. Once reconstituted, standard laboratory handling practice applies. This page does not provide dose guidance or medical information.
