TB-500 β Research Overview
4 min read Β· Updated 2026-07-24
TB-500 is a synthetic peptide frequently studied alongside BPC-157 in tissue-repair research. This overview covers what it is and the scientific contexts in which it appears.
What TB-500 is
TB-500 is a synthetic peptide related to a naturally occurring region of thymosin beta-4 (TΞ²4), a protein involved in cell migration and actin regulation. TB-500 corresponds to an active fragment of that protein and is used as a stable, synthesisable reference compound in laboratory research.
At East Coast Labs, TB-500 is supplied lyophilised with an independently published Certificate of Analysis per batch.
Areas of scientific research interest
Preclinical literature has examined thymosin beta-4 and related fragments in experimental models of:
- Cell migration and actin-cytoskeleton dynamics
- Tissue-repair and regeneration research
- Angiogenesis signalling
- Extracellular-matrix remodelling studies
TB-500 is one of the two compounds in our Recovery & Repair stack, paired with BPC-157 β the combination most often seen together in connective-tissue research.
These describe research contexts only β not efficacy claims. TB-500 is not approved for therapeutic use by any regulatory authority.
Physical & handling properties
