Overview

A synthetic fragment of Thymosin Beta-4, a protein involved in cell migration, differentiation, and tissue repair.

Mechanism of action

Binds G-actin and promotes actin polymerization, enabling cell migration; upregulates VEGF for angiogenesis.

Typical protocol

2–5 mg subQ weekly, 4–6 week loading phase, then maintenance.

Storage

Reconstituted: refrigerated, ~30 days. Lyophilized: room temp 12+ months.
