TB-500 Peptide | 5mg | Research Grade

TB-500 UK availability is one of the most common research queries we receive — this page covers everything you need before ordering, including mechanism, purity testing, and storage guidance.

What Is TB-500?

TB-500 is the research name for a synthetic peptide fragment derived from Thymosin Beta-4 (TB4), a protein naturally present in nearly all human and animal cells at high concentrations, particularly in platelets and wound-repair tissue. TB-500 represents the biologically active region of the larger TB4 protein, synthesised in isolation for laboratory research purposes.

ApexPure’s TB-500 5mg is manufactured to research-grade specification as a lyophilised powder for laboratory use only. The compound is studied primarily for its relationship to actin, a structural protein central to cell shape, movement, and division, making it a subject of interest across cytoskeletal and cell-motility research programmes.

Research Applications

Published in-vitro research has examined TB-500 in relation to actin-binding activity and its downstream effects on cell migration assays. Researchers have used TB-500 in wound-model cell cultures to study fibroblast and keratinocyte movement, and in angiogenesis-adjacent research examining endothelial cell behaviour. It is frequently studied alongside BPC-157 in comparative tissue-signalling research, as the two compounds are thought to act through different but potentially complementary mechanisms within regenerative-biology research models.

Background & Research History

Thymosin Beta-4, from which TB-500 is derived, was first characterised for its role in actin sequestration and cellular motility in the late 20th century. Research interest in the shorter, synthetic TB-500 fragment grew as scientists sought a more stable, laboratory-practical version of the actin-regulation research profile associated with the full-length protein. It has since become a standard reference compound in tissue-repair and regenerative-science literature, frequently appearing in animal-model studies alongside other structural and signalling peptides.

Purity & Third-Party Testing

Each ApexPure batch of TB-500 is independently HPLC-tested to confirm a minimum of 99% purity. Certificates of Analysis are batch-matched, meaning the specific COA available on this listing corresponds exactly to the vial you receive, identified by a printed batch number. We do not rely on generic or historical testing documentation — every batch is tested on its own merits before release.

Reconstitution & Storage Guidelines

Keep lyophilised TB-500 frozen at -18°C or below and shielded from light prior to use. Once reconstituted with bacteriostatic water, store the solution at 2–8°C and use within the timeframe specified by your laboratory protocol. As with all peptide compounds, minimise freeze-thaw cycling to preserve structural integrity and ensure consistent results across research sessions.

Handling Notes for Researchers

TB-500 should be handled exclusively by trained laboratory personnel under appropriate research conditions, using standard PPE and following your institution’s documented handling and disposal protocols. ApexPure supplies this compound strictly for scientific investigation and does not provide guidance on administration or dosing outside a controlled research setting.

Why Buy TB-500 UK From ApexPure

ApexPure was built around one standard: every batch we sell is independently tested before it reaches your laboratory, and every Certificate of Analysis is published, not hidden behind a support request. TB-500 is commonly ordered alongside BPC-157 for combined tissue-repair research protocols, and we test both compounds to the same independent standard so researchers can trust consistency across a combined study design. Orders are dispatched from the UK, so researchers avoid the customs delays and cold-chain uncertainty that come with importing from overseas suppliers. If a batch does not meet our purity threshold, it does not go on sale — that is the certification promise behind the ApexPure name. Read more about our testing process, or check our FAQ for common questions about ordering and dispatch. Our facility operates under documented quality-control procedures, with every incoming batch checked against its accompanying Certificate of Analysis before it is released into inventory. We work with independent, third-party laboratories rather than relying on internal or manufacturer-supplied test data, which is a distinction researchers increasingly look for when comparing UK suppliers. Packaging is designed to protect peptide integrity in transit, and orders are typically dispatched within one to two working days of purchase.

Frequently Asked Questions

How is TB-500 different from BPC-157?

They are structurally distinct peptides studied via different primary mechanisms — TB-500 relates to actin regulation and cell motility, while BPC-157 is studied primarily in angiogenesis and gut-protective research models. Many researchers study both compounds within the same tissue-repair research programme.

Does ApexPure provide a COA for every batch?

Yes. Every product ships with access to a batch-specific, independently verified Certificate of Analysis, downloadable directly from the product page.

What is the shelf life of unreconstituted TB-500?

Properly stored at -18°C or below and protected from light, lyophilised TB-500 remains stable for an extended period. Always check the batch documentation for any specific storage guidance.
