The full catalog.

UKPeptides supplies research-grade peptides to laboratories, universities and qualified researchers across the United Kingdom. Every compound in our catalogue is intended strictly for in-vitro research and laboratory use — never for human or veterinary use or consumption. Our focus is simple: verified quality, honest documentation and reliable cold-chain delivery.

Verified purity — ≥99% HPLC

Purity matters in research, so every production lot is verified by High-Performance Liquid Chromatography (HPLC) to ≥99%, with identity confirmed by mass spectrometry (LC-MS). Analysis is carried out by an independent, third-party laboratory before release, and the results are tied to the lot number printed on your vial. You can read more on our purity & testing page.

Quality assurance & documentation

A batch-specific Certificate of Analysis (COA) is available for every order. It documents the HPLC chromatogram, mass-spec identity confirmation and the batch number, giving you clear, lot-level traceability. If the batch number on your COA does not match your vial, it isn't your document — and we want to know about it.

Popular research compounds

Our range spans GLP-1 receptor agonists, growth-hormone secretagogues, tissue and cosmetic peptides and more. Frequently studied compounds include BPC-157, TB-500 and the copper-binding tripeptide GHK-Cu — each listed with its full identifier, CAS number where applicable, molecular data and storage guidance.

Handling, storage & reconstitution

Peptides are supplied lyophilised. Kept sealed at −20°C in a monitored freezer, lyophilised material stays stable for long-term storage. Reconstitute with bacteriostatic water using careful, sterile technique; once reconstituted, store refrigerated and use within a reasonable window to preserve stability. Our step-by-step reconstitution guide walks through the process.

Cold-chain shipping across the UK

Heat, moisture and time degrade peptides, so we ship lyophilised in insulated, temperature-shielded packaging, with same-day UK dispatch on orders placed before 3 pm. Tracking is provided at checkout — see our shipping & cold-chain page for full details.

Research use & compliance

All products are sold strictly for laboratory research use only. They are not medicines, supplements or controlled substances, are not intended to diagnose, treat or prevent any condition, and are not for human or veterinary use. By ordering, you confirm that you are a qualified researcher and will use these materials lawfully.
