Overview
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide found in virtually all human and animal cells. It plays a critical role in actin regulation, cell migration, angiogenesis, and wound healing. Unlike BPC-157 which is best used locally, TB-500 exerts systemic healing effects throughout the body.
Mechanism of Action
TB-500 binds to actin (the protein that forms cellular scaffolding), promoting cell migration and proliferation. It upregulates the expression of beta-4 integrins on cell surfaces, facilitating tissue repair and new blood vessel growth. It also has potent anti-inflammatory properties through inhibition of inflammatory cytokines.
Use Cases
- ✓Systemic tissue healing and recovery
- ✓Chronic injury rehabilitation
- ✓Cardiac muscle protection post-injury
- ✓Hair regrowth (emerging research)
- ✓Inflammatory conditions
- ✓Athletic performance recovery
- ✓Neurological injury support
Research Summary
TB-500 has shown efficacy in numerous animal studies including cardiac repair following myocardial infarction, corneal healing, dermal wound closure, and neurological recovery. A Phase II clinical trial studied Thymosin Beta-4 for dry eye syndrome. Preclinical athletic recovery studies show significantly faster return-to-performance metrics.
Typical Dosing
2–2.5 mg twice per week during loading phase (4–6 weeks), then 2 mg per month for maintenance. Subcutaneous or intramuscular.
