How to Use Thymosin Beta-4
Complete guide to Thymosin Beta-4 dosing, administration, timing, and protocol recommendations.
Quick Overview
Thymosin beta-4 (Tbeta4) is a small 43 amino acid peptide found in nearly every cell in the body, originally isolated from the thymus. Its main job is binding and sequestering G-actin, the building block of the cell's internal scaffolding, which lets it influence cell movement, wound repair, and tissue regeneration. It is researched heavily for healing of skin, cornea, and heart tissue, but it is not an FDA-approved drug. (The injectable sold as TB-500 is a synthetic fragment marketed as related to Tbeta4, not the full natural peptide.)
