About TB-500

TB-500 is a healing and recovery peptide researched for tissue repair, wound healing, flexibility, muscle recovery and reduced inflammation — a staple in injury and regenerative research.

TB-500 is a synthetic analogue of thymosin beta-4, the principal actin-sequestering peptide in mammalian cells. It is studied in cytoskeletal biology, cell motility and wound-closure models in culture.

Supplied by Veyrona Labs as a lyophilised powder for in-vitro laboratory research use. This compound has not been authorised by Health Canada for any therapeutic, clinical, veterinary or human use.
