TB-500: What the Research Shows on Tissue Repair
TB-500 is a synthetic analogue of Thymosin Beta-4, naturally involved in actin polymerisation, cell migration, and wound healing. It has been studied for systemic rather than local activity, with research examining repair across multiple tissue types.

TB-500 is a synthetic analogue of Thymosin Beta-4, a naturally occurring protein involved in actin polymerisation, cell migration, and wound healing. It is distinguished from many repair peptides in research by its proposed systemic action: rather than acting only at a site of injury, it circulates, and studies have examined its effects across multiple tissue types.
Mechanism of Action
Thymosin Beta-4 binds to G-actin (monomeric actin) and sequesters it, regulating cytoskeletal dynamics and cell motility. TB-500, the active fragment of this protein, shares this actin-binding activity and has been studied in preclinical models for roles in angiogenesis, inflammation, cardiac tissue repair, and wound closure. Its proposed systemic action is why it has attracted research interest in relation to multiple sites of injury.
What the Research Shows
TB-500 has been studied in cardiac repair models (following myocardial infarction), wound healing including corneal and dermal repair, and musculoskeletal recovery. Animal studies have reported reduced inflammation and faster functional recovery. It has also been used in veterinary medicine, particularly in racehorses, although human clinical data remain limited.
Areas of Research Interest
Research interest in TB-500 has focused on tendon and ligament injury, post-surgical tissue repair, and recovery where multiple tissue systems are under stress. It is often discussed alongside BPC-157 in the so-called Wolverine Stack.
