From the published research
Another active site at the amino terminus contains 15 aa, including Ac-SDKP, and promotes cell survival and blocks apoptosis, while a short sequence containing LKKTETQ, the central actin-binding domain (aa 17-23) plus 1 additional amino acid (Q), promotes angiogenesis, wound healing, and cell migration.
In research models, TB-500 has been observed to upregulate cell-building proteins such as actin, promoting cellular migration and proliferation. Studies suggest it may downregulate inflammatory cytokines and promote new blood vessel growth in tissue models. Areas of research interest include: Cellular repair and regeneration studied in preclinical models; Anti-inflammatory properties observed in research; Wound and tissue remodelling effects investigated.
Is TB-500 third-party tested?
Yes. Each batch of TB-500 is analyzed by an independent third-party laboratory. Batch TB501 (results dated December 18, 2025) reported average purity of 99.32% and average mass of 5.08 mg. Full Certificate of Analysis documentation is available for this product.
What does published research say about TB-500?
Extensive preclinical research investigating wound tissue-model pathway activity, cardiac tissue remodelling, and anti-inflammatory effects. Published studies span multiple tissue types and animal models. This page cites 2 published references for further reading.
Who typically studies TB-500 in a laboratory setting?
This peptide is supplied as a lyophilized (freeze-dried) powder. Bacteriostatic water is required to reconstitute it before use and is not included with this product. Store lyophilized (powder) form at room temperature or refrigerated. After reconstitution, store refrigerated (2-8°C) and use within 30 days.

TB-500
A synthetic fragment of the naturally occurring peptide Thymosin Beta-4, a 43-amino acid protein involved in cell migration and tissue remodelling. Studied in preclinical models for its role in cellular repair processes.
CAS number: 77591-33-4.
In research models, TB-500 has been observed to upregulate cell-building proteins such as actin, promoting cellular migration and proliferation. Studies suggest it may downregulate inflammatory cytokines and promote new blood vessel growth in tissue models.
TB-500 is supplied for laboratory research use only. It is not for human or animal use, clinical use, diagnostic use, therapeutic use, or personal-use protocols.
Each MyPeptide reference page is organized around product identity, documentation, and research context rather than medical claims, dosing instructions, or personal-use outcomes.
Use the related links on this page to move between the catalog, COA records, policy pages, and supporting research guides while staying within the research-use-only scope.
Batch documentation, product identity, and compliance context are kept close together so qualified purchasers can review the material before continuing through the storefront.
