Does TB-500 help injury recovery?
Some research is on the full protein, thymosin beta-4, not the small fragment the FDA discusses as TB-500. A dry-eye trial of the full protein didn’t clearly beat placebo on its two main measures.

What the human studies found
- Sold, like BPC-157, for injury recovery.
- The FDA describes TB-500 as a seven-amino-acid fragment of thymosin beta-4.
- One trial tested eye drops containing the full protein for dry eye. It didn’t clearly beat placebo on its two main measures: eye discomfort and a staining test of the eye’s surface. Some secondary measures improved.
- That doesn’t test whether a fragment repairs a sports injury.
- A new registry record from a sponsor in Shenzhen had no results posted as of October 2, 2026.

We checked the human research behind 16 peptides. The question wasn’t just “is there a study?” It was “does that study support the pitch?” For each one: who took part, what was measured, and what actually changed.
