  • TB-500, derived from the naturally occurring protein Thymosin Beta-4, is a synthetic peptide that binds to a protein called actin, which is involved in the formation of new blood vessels and the repair of damaged tissues. By binding to actin, TB-500 helps stimulate the growth of new blood vessels and promotes the formation of new tissue functions.

The ability of TB-500 to reduce inflammation and promote cell migration, proliferation, and differentiation, which can help to facilitate tissue repair and regeneration has been demonstrated in various research. It is currently studied for its potential to enhance athletic performance and improve recovery from injury.
