    TB-500 peptide (Thymosin Beta-4 Fragment) Research Peptide

Category: Tissue-Repair Peptide

Form: Lyophilized powder

Intended Use: Laboratory research

Overview

tb 500 peptide is a synthetic peptide fragment based on the active region of thymosin beta-4 (Tβ4), a 43-amino-acid protein naturally found in nearly all human and animal cells, including high concentrations in blood platelets and wound fluid. Thymosin beta-4 plays a central role in actin regulation — the cellular machinery responsible for cell movement — which underlies its research interest in cell migration, blood vessel formation (angiogenesis), and tissue repair signaling. TB-500 is supplied here strictly as a raw research compound for qualified laboratory use.

Quality Assurance tb 500 peptide​

Each batch is accompanied by a third-party Certificate of Analysis (COA) verifying purity and identity. COAs are available on request or via the product page prior to purchase.

Research Applications

TB-500 and its parent molecule thymosin beta-4 have been referenced in published research on:

• Cell migration and angiogenesis  via actin monomer binding, relevant to models of new blood vessel formation
• Tissue repair models  studies span muscle, tendon, ligament, skin, and gastrointestinal tissue in animal research
• Inflammatory signaling  preclinical work reports modulation of inflammatory cytokines
• Ocular and neurological research early-stage interest includes dry eye and neuroprotection models

Thymosin beta-4 (under the development name RGN-137/RGN-352) has been studied by RegeneRx Biopharmaceuticals through early-stage human clinical trials for wound healing and dry eye syndrome, giving this molecule family more clinical development history than many research peptides. However, TB-500 specifically — the synthetic fragment sold for research — has not itself completed human clinical trials or received regulatory approval.

Regulatory and Compliance Note tb 500 peptide​

TB-500 has been on the World Anti-Doping Agency (WADA) Prohibited List since 2011; it is not permitted for use by competitive athletes subject to anti-doping rules. In the US, TB-500 is one of several peptides under review by the FDA’s Pharmacy Compounding Advisory Committee regarding potential future compounding pathways — a review is not the same as approval, and as of this listing TB-500 remains unapproved for human use.
