TB-500 is a synthetic fraction of the 43 amino acid protein thymosin beta-4. The main purpose of this peptide is to promote healing. The healing effects of TB-500 have been observed in tendons, ligaments, muscles, skin, heart, and eyes. It aids in the quick healing of wounds by promoting new blood vessel and muscle fiber growth. It upregulates cell building proteins like actin and stimulates hair growth.

Thymosin is a hormone secreted from the thymus with the function to stimulate production of T cells in the immune system and assist in develop of B cells in the immune system to produce antibodies.  The main form of thymosin is thymosin beta-4 is an actin cell building protein.   Actin is a cell building protein with a primary role in protection, regeneration, and remodeling of damaged tissue.  After an injury is sustained in the body, it releases TB4 to protect damaged cells and tissues as well as reduce inflammation and microbial growth.  TB500 promotes angiogenesis (formation of new blood vessels) in the injured tissue to increase blood, nutrients, and growth factors.   TB500 decreases cytokines which decreases inflammation.
