TB4-FRAG Dosing Protocol: TB-500 Fragment Guide
Also known as: TB-500 Fragment, Thymosin Beta-4 Fragment
What is a Peptide?
A short chain of amino acids (2-50) linked by peptide bonds. Smaller than proteins. Your body produces thousands of peptides naturally as signaling molecules that regulate everything from appetite to healing. Therapeutic peptides mimic or enhance these natural signals.

Overview
TB4-FRAG is the active fragment of Thymosin Beta-4 (TB-500). This 4-amino acid fragment retains many of the regenerative properties of full-length TB-500.
Mechanisms of Action
- Upregulates actin polymerization promoting cell migration
- Promotes angiogenesis and new blood vessel formation
- Anti-inflammatory effects reducing tissue damage
- Enhances wound healing and tissue regeneration
