Research Peptides UK — HPLC-Tested Compounds for Laboratory Use

MyPep Biotech is a UK peptide supplier providing research peptides to laboratories, universities and independent researchers across the United Kingdom. As a trusted research peptide supplier, every compound in our catalogue is manufactured to a stated purity standard, verified in-house or through third-party HPLC analysis, with supporting batch documentation published where currently available so researchers can review the analytical information before a study begins. Grounded in peptide science UK researchers can rely on, our peptide shop makes it straightforward to buy peptides UK-side. If you are deciding where to buy research peptides in the UK, or want to learn more about peptide science UK standards, our sourcing guide sets out the quality standards worth checking first.

Why Researchers Choose a UK-Based Peptide Supplier

Sourcing research peptides from a domestic supplier reduces the customs delays, temperature excursions and documentation gaps that often accompany overseas orders. Our UK dispatch process uses tracked domestic delivery and protective packaging intended to reduce unnecessary transit delays. For time-sensitive protocols, that consistency matters as much as purity itself.

What Is Peptide Purity Testing, and Why It Matters for Research

High-performance liquid chromatography (HPLC) separates a sample into its component parts, allowing a lab to measure how much of a vial's contents is the target peptide versus residual synthesis by-products, salts or degradation fragments. A peptide advertised at 99%+ purity should have documentation showing that figure was measured on the specific batch shipped — not a general marketing claim carried over from an earlier production run. Researchers should review the documentation available on the relevant product page before recording material details.

Our Research Peptide Categories

Our current range spans several areas of ongoing peptide research:

• Metabolic and appetite-signalling peptides — including GLP-1 and GIP receptor agonist analogues such as Semaglutide, Tirzepatide and Retatrutide, widely used in laboratory models of energy metabolism and glucose regulation.
• Regeneration and tissue-repair peptides — including BPC-157 and TB-500, studied for their role in models of wound healing, angiogenesis and soft-tissue recovery.
• Cellular and dermal signalling peptides — including GHK-Cu, a copper-binding tripeptide studied in models of collagen synthesis and tissue remodelling.
• Metabolic co-agonists — including Cagrilintide, an amylin analogue frequently paired with GLP-1 agonists in combination research protocols.
• Mitochondrial peptides — including MOTS-c, a mitochondrial-derived peptide studied for its signalling role in metabolic research models.

Each product page includes molecular details, storage guidance and links to relevant published research, so you can evaluate whether a compound fits your protocol before ordering.

Storage, Handling and Documentation

Peptides are sensitive to temperature, light and repeated freeze-thaw cycles. We recommend researchers store lyophilised peptides at -20°C or below until reconstitution, use bacteriostatic or sterile water appropriate to the compound, and log reconstitution dates alongside batch numbers for traceability. Our Research Guides section covers reconstitution calculations, storage stability windows and general handling practices in more depth.

For Laboratory and Research Use Only

Every product supplied by MyPep Biotech is intended strictly for in-vitro laboratory research and is not manufactured, labelled or sold for human or animal consumption, diagnostic use or therapeutic application. Researchers are responsible for ensuring their use of any compound complies with relevant institutional, ethical and regulatory requirements before beginning a study.
