TB-500

A thymosin beta-4 fragment studied for tissue repair, flexibility, and reduced inflammation.

In the literature, TB-500 appears most often in work focused on injury recovery, healing and flexibility. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.

Because it is catalogued here under powder peptides, TB-500 also shows up in discussions of inflammation. Coverage across those topics varies widely in quality and depth, and much of it is early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.
