Its believed to promote musculoskeletal repair by upregulating growth factors, stimulating the formation of new blood vessels, or modulating nitric oxide synthesis, but no mechanism of action has been proven.34 TB4, however, has known mechanisms by which it speeds recovery from injury: inhibiting inflammation, preventing cell death, and (as suspected with BPC) promoting blood vessel formation.35 On top of the benefits for physical recovery, the ability to form new blood vessels points to promising implications for cardiovascular health
There is also research, McGuire says, suggesting it might help preserve nerve connections with injured muscles (or muscles recovering from a hard workout)
Instead, it represents glutathione that has completed an antioxidant task, and is ready for recycling
