BPC-157 vs TB-500: Which Healing Peptide Is Better?

Both BPC-157 and TB-500 are popular healing peptides in research, but they work through different mechanisms and excel in different situations.

BPC-157 Overview

BPC-157 (Body Protection Compound-157) is a pentadecapeptide derived from gastric juice. It primarily works by upregulating VEGF (vascular endothelial growth factor) and modulating the nitric oxide system.

• Best for: Tendon/ligament injuries, gut healing, localized repair
• Typical dose: 250-500 mcg, 1-2x daily
• Half-life: ~4 hours

TB-500 Overview

TB-500 (Thymosin Beta-4 fragment) promotes cell migration and blood vessel formation. It works systemically rather than locally.

• Best for: Systemic healing, muscle injuries, flexibility, cardiac repair
• Typical dose: 2-5 mg, 2x weekly
• Half-life: Long systemic presence

Stacking BPC-157 + TB-500

Many researchers combine both for synergistic healing - BPC-157 for localized repair and TB-500 for systemic tissue remodeling.
