TB-500 (Thymosin Beta-4 Acetate) sourced directly from China. Batch-verified, purity tested per batch. 5mg & 10mg vials for research use.
TB-500 (thymosin beta-4 fragment) remains a staple of china peptide catalogs, valued for actin-sequestration studies and cell-migration models. Among chinese peptides suppliers, TB-500 is also one of the most frequently counterfeited compounds, which is exactly why batch-level purity documentation matters more than the listing price. Our catalog carries it as a finished lyophilized vial from an established Chinese facility, with the specification recorded per batch.

Compound Profile
TB-500 (Thymosin Beta-4 Acetate) is a synthetic 43-amino acid polypeptide corresponding to the full sequence of Thymosin Beta-4, a naturally occurring protein found in virtually all mammalian cells and the most abundant G-actin-sequestering protein in eukaryotic cells. Unlike locally-acting peptides, TB-500’s primary research interest lies in its systemic distribution and its role in actin regulation — the structural process fundamental to cell migration, differentiation, and tissue remodeling. Preclinical research in rodent and rodent-based cardiac models has examined TB-500 in contexts including wound closure, ischemia-reperfusion injury recovery, and musculoskeletal injury models. Its mechanism of interest centers on G-actin sequestration and promotion of cellular migration, which distinguishes it from BPC-157’s more localized gastroprotective and repair profile. Peptides of China supplies TB-500 as a lyophilized powder in 5mg and 10mg vials, synthesized to 99%+ purity verified by HPLC and Mass Spectrometry. Every batch is tested by the manufacturer for purity and concentration as part of routine quality control. All products are intended for laboratory research use only and are not for human consumption.

Research Areas
Wound and Skin Repair TB-500 has been studied in multiple wound healing models, including full-thickness dermal wound studies in rodents. Research has focused on the compound’s apparent acceleration of re-epithelialization and angiogenesis through G-actin sequestration and cellular migration promotion — key processes in tissue remodeling. Cardiac and Vascular Research Cardiac research represents one of the most studied areas of Thymosin Beta-4 activity. Rodent studies in ischemia-reperfusion injury models have examined its apparent role in cardiomyocyte survival and neovascularization following myocardial infarction, with proposed mechanisms involving actin cytoskeletal regulation and anti-apoptotic signaling. Musculoskeletal Recovery Rodent models of muscle injury have examined systemic TB-500 administration in contexts of muscle fiber repair and post-injury fibrosis reduction. Research interest in this area is driven by the compound’s systemic distribution profile, which differentiates it from locally-acting repair peptides like BPC-157. ## Sourcing TB-500 From China
TB-500 is available through our platform as a china peptide sourced directly from an established Chinese manufacturer. Three points define how we handle it:
- Factory-direct, not trader-sourced. We confirm availability and specification with the manufacturer before the order is confirmed. There is no intermediary resale of unknown-origin vials in this catalog.
- Specification before shipment. The purity and concentration specification shown on this page is the manufacturer’s batch specification. Product-specific quality-control information travels with the order.
- Research-use discipline. Like every listing in our catalog, TB-500 is supplied for laboratory research use only, under strict research-use terms.
For buyers comparing chinese peptides suppliers, the practical test is whether the seller can name the manufacturer and show the batch documentation. We work the other way around: the manufacturer and the documentation are the offer. Browse the full catalog or see how sourcing works.
