TB-500 and Thymosin Beta-4: Understanding the Healing Peptide

TB-500 is the synthetic active fragment of thymosin beta-4 — here's how it works and what the research shows.

From Thymosin Beta-4 to TB-500

Thymosin beta-4 is a 43-amino acid protein naturally present in almost all human cells, with particularly high concentrations in platelets and wound fluid. TB-500 is a synthetic fragment of thymosin beta-4 that captures the active healing properties in a more stable, manufacturable form. This distinction is important because TB-500 is not identical to full-length thymosin beta-4, though they share key functional properties.

The peptide works primarily by promoting cell migration and differentiation, which are essential processes in tissue repair and regeneration.

Key Healing Mechanisms

TB-500 promotes wound healing through actin sequestration and cell migration enhancement. It helps cells move to injury sites, supports blood vessel formation, and reduces inflammation. The peptide also upregulates anti-apoptotic factors, helping cells survive under stress conditions. These mechanisms make TB-500 relevant for soft tissue injuries, cardiac recovery, and potentially neurological repair.

Typical Protocols

TB-500 is commonly used at 2-2.5 mg subcutaneously twice weekly for 4-6 weeks, followed by a maintenance phase of 1-1.5 mg monthly. For injury recovery, some protocols combine TB-500 with BPC-157 for synergistic effects. Use our TB-500 dosage calculator to determine exact dosing for your specific protocol.
