What it is — A synthetic fragment of Thymosin Beta-4 — the protein the body upregulates at every injury site within hours of damage. Backed by over 100 published studies in tissue repair research. Why it's studied — TB-500 binds to G-actin and influences how cells migrate, organize, and rebuild tissue architecture. Research has documented effects across cardiac, muscle, tendon, and corneal repair models — making it one of the most versatile compounds in regenerative science. Key research findings

• Accelerated stem cell migration to injury sites (Goldstein et al., cardiac repair models)

• Reduced fibrosis and improved tissue quality in muscle and tendon studies

• Documented neuroprotective effects in traumatic brain injury animal models
