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 | 4/10 | 6/10 |
| 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 (a short chain of amino acids, the building blocks of proteins) that's sold widely as a "healing" and recovery product. It's important to keep it separate from the natural protein it's copied from, because a lot of the upbeat marketing borrows trust from research that…
Thymosin Beta-4
Thymosin beta-4 stands out from most "research peptides" for one simple reason: it has actually gone through real, registered, peer-reviewed human trials. That is its honest claim to fame. But it is also where the story gets complicated, because its most-studied use has now fallen short of its main…
