TB500 (Thymosin B4 Acetate)
A synthetic fragment of thymosin β-4 that promotes cell migration, angiogenesis, and tissue repair.
How it works
Sequesters G-actin and modulates the actin cytoskeleton, enabling endothelial and stem-cell migration into injured tissue. Upregulates VEGF and PDGF.
Reported benefits
- Accelerated soft-tissue and corneal wound healing in pre-clinical models
- Cardioprotection after ischemic injury in mice
- Hair-follicle stem-cell migration support
Dosage & administration
Research loading: 2.5 mg twice weekly for 4-6 weeks, then 2.5 mg weekly maintenance.
Dosing information is summarised from published clinical and pre-clinical literature for research purposes only and does not constitute medical advice.
