TB-500
Also known as: Thymosin Beta-4 · Thymosin β-4 · TB500 · Tβ4 fragment
A synthetic fragment analog of Thymosin Beta-4, studied for cell migration, full-body tissue repair and flexibility.
TB-500 is a synthetic peptide based on a fragment of Thymosin Beta-4 (Tβ4), a naturally occurring protein present in almost all human cells and in high concentration in wound fluid and platelets.
Research interest centres on actin regulation and cell migration — mechanisms relevant to wound closure, tissue repair and reduced adhesion/scar formation. Because Tβ4 is expressed body-wide, TB-500 is often studied for systemic rather than localised repair, which is why it is commonly paired with BPC-157.
Supplied lyophilised for research use only. Reconstitute with bacteriostatic water before study; every batch ships HPLC-verified with a Certificate of Analysis.

Thymosin
A family of thymus-associated peptides; Thymosin Beta-4 underlies TB-500’s tissue-repair research.
Lyophilised
Freeze-dried. Peptides are supplied as a lyophilised powder/pellet for stability, then reconstituted before study.
Reconstitution
The process of dissolving a lyophilised (freeze-dried) peptide in a sterile solvent such as bacteriostatic water before study.
Half-Life
The time for a compound’s concentration to fall by half — a key determinant of dosing frequency in research.
Certificate of Analysis (CoA)
A batch-specific lab document reporting a compound’s identity and purity — the primary proof of what is in the vial.
