TB-500 is a man-made version of a natural peptide called Thymosin Beta-4. This peptide helps our bodies fix damaged tissues and heal wounds. It works by helping cells move to the areas that need repair.
How Does it Work?
TB-500 helps wounds heal faster and fixes damaged tissues. It does this by helping cells move to the right places (Huff et al., 2007). Scientists have found that it can help heal different types of tissues, like the eyes and heart.

TB-500 is supplied as a lyophilized powder. Keep it sealed, dry, and away from light until reconstitution.
Lyophilized material is stable when frozen. Once reconstituted, keep it cold and minimise handling to preserve integrity.
TB-500 is a synthetic peptide compound used in laboratory research settings. Researchers studying tissue repair and regeneration mechanisms use this compound to investigate cellular signaling pathways, receptor binding affinities, and structure-activity relationships.
