BPC-157 vs TB-500 — comparison summary

This page compares BPC-157 and TB-500 across mechanism of action, receptor targets, molecular weight, solubility and research focus, for in vitro research use only.

BPC-157

A stable gastric pentadecapeptide widely studied for tissue repair.

Mechanism
A synthetic 15-amino-acid fragment of a gastric protein studied for promoting angiogenesis (new blood-vessel formation) and tissue repair in preclinical models.
Receptor targets
Acts largely through growth-factor and nitric-oxide pathways; no single named receptor — modulates the VEGFR2 / NO system.
Molecular weight
1419.5 g/mol
Solubility
Highly water-soluble
Research focus
Extensively studied in vitro and in animal models for tendon, ligament, muscle and gut-lining repair.

TB-500

The active fragment of Thymosin Beta-4, studied for cell migration and repair.

Mechanism
A synthetic fragment of Thymosin Beta-4 that binds and regulates actin, supporting cell migration and tissue repair in preclinical work.
Receptor targets
No classical receptor — acts intracellularly via actin sequestration.
Molecular weight
889 g/mol
Solubility
Highly water-soluble
Research focus
Studied in models of wound healing, cardiac repair and flexibility of connective tissue.
