TB-500 is a synthetic analog of the 43-amino acid peptide Thymosin Beta-4, one of the most abundant intracellular peptides found in mammalian tissue. Its research profile centers on actin regulation, angiogenesis, and inflammation modulation, areas of significant interest to researchers studying recovery timelines and wound healing models.
What distinguishes TB-500 in research contexts is its small molecular size relative to full Thymosin Beta-4 and its documented stability in lyophilized form, allowing consistent dosing protocols in laboratory settings.

- What it is: A synthetic peptide tied to Thymosin Beta-4, a small protein found in nearly every cell in the body.
- Researchers have studied it for: How cells move to close a wound, skin and tissue repair after injury, and new blood vessel growth.
- Evidence level: Mostly animal models, plus a few small human trials of Thymosin Beta-4 itself.
- The short version: The human studies here are on Thymosin Beta-4, the natural protein, not on the research-labeled “TB-500” by that name. Researchers looked at how the protein helps skin and vessel cells crawl toward a wound to close it. The human trials are small and early, and none of this is a safety conclusion.
