TB-500 vs Thymosin Beta-4
Both are healing peptide compounds. Here's how they line up on the evidence — graded the same way.
| TB-500 | Thymosin Beta-4 | |
|---|---|---|
| Evidence | Animal only | Preliminary human |
| Class | Healing peptide | Healing peptide |
| Summary | TB-500 is a synthetic thymosin beta-4 fragment marketed for healing, but human data on the fragment itself is essentially absent and the supporting research is animal-only. | Full-length thymosin beta-4 has genuine human trials for eye-surface and wound healing, but the evidence is small, sponsor-driven, and largely missed its primary endpoints. |

TB-500
TB-500 is a lab-made peptide sold widely as a "healing" and recovery compound. It is worth separating clearly from the natural protein it is derived from, because much of the optimistic marketing borrows credibility from research that did not actually use TB-500.
Thymosin Beta-4
Thymosin beta-4 is unusual among "research peptides" because it has actually been through registered, peer-reviewed human trials. That is the honest selling point — and also where the story gets complicated, because the best-studied use has now missed its primary endpoint in two separate Phase 3…
