Larazotide vs TB-500

An educational, source-based comparison of Larazotide and TB-500 — how each peptide works, what it's researched for, and what to know before going deeper.

Gastrointestinal · Barrier
Larazotide

Tight junction regulator studied for celiac disease.

Mechanism

An octapeptide zonulin antagonist that helps maintain intestinal tight junction integrity, reducing paracellular permeability triggered by gluten in celiac disease.

Research areas
  • Celiac disease (Phase 3 completed)
  • Intestinal barrier function ('leaky gut' research)
  • Environmental enteropathy
Considerations
  • Not yet FDA-approved.
  • Investigational; physician oversight required.

Tissue Repair · Vascular
TB-500

Synthetic fragment of Thymosin Beta-4 studied for tissue and vascular repair.

Mechanism

A synthetic peptide fragment of Thymosin Beta-4 (Tβ4). Research suggests it upregulates actin, promotes cell migration, angiogenesis, and modulates inflammation — supporting repair in muscle, tendon, cardiac, and corneal tissue models.

Research areas
  • Muscle and tendon repair
  • Cardiac tissue recovery (preclinical)
  • Corneal and dermal wound healing
  • Hair follicle stem cell activation
Considerations
  • Not FDA-approved; banned by WADA.
  • Most evidence is preclinical.
