SUPPLIED QUANTITY & FORMAT
Vial quantity, not a dosing schedule.
This listing supplies 5 mg per vial, with 10 vials per pack. The labeled quantity describes the material supplied; it is not a recommended dose or a prepared-solution concentration. No human or animal dosing instructions are provided.
Freeze-dried powder
The supplier describes the material as lyophilized, or freeze-dried, powder. Lyophilization removes water from a frozen preparation. The dry vial is not a ready-to-use liquid, and a labeled mass does not specify a final concentration. Follow the batch-specific technical documentation for laboratory handling and storage. Freeze-drying alone does not establish purity, sterility, or shelf life; review the supplier’s batch documentation.
COMPOUND OVERVIEW
What is TB500?
A supplier product name associated with thymosin beta-4-related peptides. The name alone does not reliably specify whether a supplier means full-length thymosin beta-4 or a fragment.
THE SCIENTIFIC QUESTIONS
What is being researched?
Published work on thymosin beta-4 and an actin-binding-domain peptide examines cell migration and experimental wound-repair endpoints. The exact sequence matters when relating a product to that literature.
Research possibilities
Sequence-defined materials can help investigate cytoskeletal behavior and repair-related cell responses. Comparing parent peptides and fragments is a research question; they should not be treated as interchangeable.
How to interpret the evidence
Confirm the sequence and molecular identity on the batch documentation. Research on full-length thymosin beta-4 does not automatically apply to a product labeled TB500.
These summaries describe published work on compounds or related materials. They are not test results for the product sold here. Reported research outcomes are not guaranteed product benefits.
Supplier and batch documentation
Peptide Express resells third-party materials in wholesale packs, fulfilled by third-party suppliers. Ask for the current certificate of analysis, composition, identity testing, and handling documentation for the actual batch. Supplier-reported testing has not been independently verified here.
Research references
Sources reviewed October 21, 2026. References are provided for research context and do not establish equivalence of supplier materials to study materials.
