Thymosin Beta-4 is a protein which consists of 43 amino acids. TB-500 is a synthetic fraction of the protein thymosin beta-4. The main purpose of this peptide is to promote healing. The effects of TB-500 have drastically improved healing in tendons, ligaments, muscle, skin, and eyes.

Thymosin Beta-4 is naturally produced in higher concentration where tissue has been damaged. This peptide is also a very potent anti-inflammatory agent. Thymosin Beta-4 works well in conjunction with other peptides therapies such as BPC-157. Thymosin Beta-4 helps decrease inflammation and increase cell migration to the cite of the injury while improving soft tissue repair. BPC-157 works in conjunction with TB4 to help support healing and reduction of pain. Both peptides work through different pathways but towards the same common goal.
