TB-500: A Research Peptide Profile

For research use only. Not for human consumption.

TB-500 is a synthetic peptide widely referenced in tissue-repair and recovery research, and is frequently studied alongside BPC-157. This profile covers what it is and how to handle it in the lab.

What is TB-500?

TB-500 is a synthetic peptide corresponding to an active fragment of Thymosin Beta-4 (Tβ4), a naturally occurring actin-binding protein. Because of its role in actin regulation and cell migration, it is a common model peptide in regenerative- and recovery-research settings.

At a glance

• Class: synthetic Thymosin Beta-4 fragment
• Research areas: actin regulation, cell migration, tissue-repair models
• Often studied with: BPC-157 (recovery-research pairing)

What research has explored

In laboratory and animal models, TB-500 has been investigated for its role in actin binding, cell migration, and tissue-repair pathways. These are areas of ongoing scientific investigation. TB-500 is supplied strictly for laboratory research and is not approved for human use; nothing here is a health, therapeutic, or efficacy claim.

Handling, reconstitution, and storage

Typically supplied as a lyophilized (freeze-dried) powder. Reconstitute with bacteriostatic water — see Reconstituting Lyophilized Research Peptides. Store lyophilized powder cold and protected from light; keep reconstituted solution refrigerated per your protocol.

Why purity and third-party testing matter

Every batch of TB-500 from FOR Peptides is >99% HPLC purity and independently third-party lab tested, with a Certificate of Analysis (COA) available. See How to Read a Certificate of Analysis (COA).
