TB-500 10mg

TB-500 10mg is a research-grade synthetic fragment of Thymosin Beta-4 supplied for laboratory study of actin regulation, tissue repair, and angiogenesis. Every batch is HPLC-tested and ships with a batch-specific third-party Certificate of Analysis (COA) confirming identity and 99%+ purity. For laboratory and research use only. Not for human consumption. This product is not a drug, supplement, food, or cosmetic and is not intended to diagnose, treat, cure, or prevent any disease.

Research Applications

TB-500 is a widely studied Thymosin Beta-4 (TB4) fragment used in regenerative and cell-motility research. In-vitro and preclinical models explore its role in actin sequestration, cell migration, angiogenesis, and wound-repair signaling. It is frequently paired with BPC-157 in comparative tissue-repair research designs.

Purity & Verification

Every lot is analyzed by reversed-phase HPLC and, where applicable, mass spectrometry to confirm compound identity and 99%+ purity. A batch-specific, third-party Certificate of Analysis (COA) is included in the product gallery so researchers can confirm purity and identity before use. Supplied as a lyophilized (freeze-dried) powder; store sealed, cool, dry, and protected from light, and reconstitute per standard laboratory handling. Fast, tracked shipping from within the United States.

Peptide Research & Literature

TB-500 is the synthetic version of the actin-binding region of Thymosin Beta-4 (Tβ4), a naturally occurring peptide studied extensively for its roles in cell migration, angiogenesis, and tissue repair. The following peer-reviewed sources may be useful background reading:

Frequently Asked Questions

What is TB-500 used for in research?
Studying actin regulation, cell migration, angiogenesis, and tissue-repair pathways in laboratory models.

Is TB-500 the same as Thymosin Beta-4?
TB-500 is a synthetic active fragment associated with the Thymosin Beta-4 protein and used as a research analog.

What purity can I expect?
99%+ HPLC-verified purity with a batch-specific third-party COA.

Can it be combined with BPC-157 in research?
The two are commonly studied together in tissue-repair research; see our BPC + TB research stack.

How should TB-500 be stored?
Short-term storage at 2-8°C and long-term storage below -10°C, protected from light and moisture, is recommended to preserve peptide stability for research use.

How is TB-500 supplied and shipped?
TB-500 is supplied as a sealed, lyophilized powder vial and shipped with the batch-specific Certificate of Analysis included.

What documentation comes with each order?
Each order includes a full third-party Certificate of Analysis confirming HPLC purity, mass spectrometry identity, peptide content, water content, endotoxin, and residual solvent results for that specific batch.

Does TB-500 require reconstitution before laboratory use?
As a lyophilized powder, TB-500 is typically reconstituted with an appropriate solvent, such as bacteriostatic water, by qualified researchers prior to use in laboratory assays.
