TB-500 is one of the most referenced synthetic peptides in European sports science and regenerative biology research. For Irish research teams seeking to source TB-500 in Ireland, this page provides a complete reference: its molecular basis, the preclinical research landscape, quality benchmarks, and how to obtain it from a verified Irish supplier with full batch documentation.
This is a research reference only. TB-500 is not a licensed medicine in Ireland or the EU. It is not approved for human or veterinary administration and is supplied exclusively for in-vitro and preclinical laboratory research purposes.
TB-500 is a synthetic analogue of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino acid protein found in virtually all human and animal cells. The TB-500 peptide corresponds to the central actin-binding domain of Tβ4 — specifically the fragment responsible for its cell migration and angiogenic activity. Its molecular formula is C₅₀H₈₃N₁₅O₁₅, with a molecular weight of approximately 1,114.2 Da.
Thymosin Beta-4 was first identified in thymic tissue and has since been found in high concentrations in blood platelets, wound fluid, and sites of active tissue repair. The synthetic TB-500 fragment allows researchers to study these mechanisms without working with the full-length protein.
TB-500’s most extensively studied research application is wound healing. In preclinical models, it has been shown to promote cell migration via upregulation of actin polymerisation, stimulate the formation of new blood vessels (angiogenesis), and reduce inflammation at wound sites. Studies in rodent models have documented accelerated closure of dermal wounds and improved tissue organisation in healing tendons and muscle fibres.
A notable strand of TB-500 research has focused on cardiac tissue. Studies in animal models of myocardial infarction have examined Tβ4 and its analogues for their potential to activate dormant cardiac progenitor cells and promote vascular remodelling. This area of research has attracted attention from cardiovascular biology groups across Europe.
TB-500 appears frequently in research examining skeletal muscle repair, tendon healing, and connective tissue remodelling. Its role in actin dynamics makes it of particular interest to researchers studying cytoskeletal responses to injury and the molecular mechanisms of fibre regeneration.
More recently, Tβ4 and related peptides have been studied in neurological contexts — particularly spinal cord injury models and neuroinflammation research. These applications remain in early preclinical stages.
As with all research peptides, purity verification is non-negotiable for TB-500. Peptides Lab Ireland supplies TB-500 with the following documentation on every batch:
All TB-500 is dispatched from within Ireland with cold-chain packaging and tracked delivery. This eliminates customs delays and protects compound integrity on arrival.
Store lyophilised TB-500 at -20°C for long-term stability. Short-term storage at 4°C is acceptable if the compound will be used promptly. Reconstitute with bacteriostatic water and keep refrigerated after reconstitution. Aliquot into single-use volumes before freezing to avoid degradation from repeated freeze-thaw cycles.
TB-500 is not a scheduled controlled substance under Irish or EU law and is not classified as a licensed medicine. It is legal to purchase and possess for in-vitro laboratory research purposes. It cannot legally be used for human administration outside an authorised clinical context. See our full guide: Are Peptides Legal in Ireland?
Thymosin Beta-4 (Tβ4) is the naturally occurring 43-amino acid protein. TB-500 is a synthetic peptide fragment corresponding to the central actin-binding domain of Tβ4. It is used in research as a more practical and cost-effective means of studying Tβ4-related biological mechanisms.
≥98% purity confirmed by HPLC, with mass spectrometry identity confirmation. All TB-500 supplied by Peptides Lab Ireland meets this standard with batch-specific documentation.
Yes — tracked, cold-packaged delivery to all addresses across the Republic of Ireland. Standard delivery is 1–3 working days from dispatch.
TB-500 is supplied by Peptides Lab Ireland for in-vitro laboratory and scientific research purposes only. It is not a licensed medicine and has not been approved for human or veterinary use by the HPRA or any EU regulatory authority. For medical concerns, consult a qualified healthcare professional.
