Third-party testedSynthetic Peptide Analogue
TB-500
TB-500 is a synthetic analogue of a naturally occurring peptide. Research focuses on its interaction with actin, cellular migration, and angiogenesis in various in-vitro tissue models.
About the compound
What TB-500 is.
TB-500 is a lab-made fragment of thymosin beta-4, a protein the body produces. Research has looked at how it affects cell migration and new blood-vessel formation in wound-healing models. Studies are in animals and cell cultures.

Research
What TB-500 has been studied for.
A plain-language summary of the published work. Almost all of it is in cells and animals — where a study was done in people, it says so.
01
Cell migration
TB-500 is a fragment of thymosin beta-4, a protein that binds actin. Laboratory research has focused on how it affects the ability of cells to move to a wound site, which is an early step in any repair process.
02
Blood vessel formation
Animal studies have investigated whether it promotes the growth of new blood vessels in wound-healing models.
03
Scar tissue and fibrosis
Rodent work has looked at whether it changes how much fibrous scar tissue forms as an injury heals, in heart and skin models.
04
Inflammation in injury models
Some animal studies have measured inflammatory markers alongside the healing endpoints.
