Larazotide Acetate vs Epithalon

Side-by-side comparison of key properties, dosing, and research.

Recovery & Repair
Larazotide Acetate
Anti-Aging & Longevity
Epithalon
Summary
Larazotide acetate is an 8-amino acid peptide (Gly-Gly-Val-Leu-Val-Gln-Pro-Gly) derived from Zonula Occludens Toxin (ZOT) of Vibrio cholerae. It paradoxically acts as a ZOT antagonist to close tight junctions and reduce intestinal permeability ('leaky gut'). It is the most advanced clinical compound targeting gut permeability directly.
Epithalon is a synthetic tetrapeptide developed from the pineal gland extract Epithalamin by Russian scientist Dr. Vladimir Khavinson. It is one of the most researched longevity peptides, known for activating telomerase and extending telomere length — the molecular hallmarks of cellular aging.

Research
Typical Dose
0.5-2 mg
5–10 mg total per cycle
Frequency
3x daily
0.5–1 mg daily
Key Benefits
  • Directly reduces intestinal tight junction permeability
  • Clinical efficacy in celiac disease (Phase 3 trials)
  • Reduces systemic inflammation from gut permeability
  • Targets root cause of leaky gut (Zonulin pathway)
  • Local gut action without systemic absorption
  • Potential application in IBS, IBD, autoimmune conditions
  • Activates telomerase enzyme, extending telomere length
  • May slow cellular and biological aging
  • Regulates melatonin production and circadian rhythms
  • Improves sleep quality
  • Powerful antioxidant properties
  • May reduce incidence of age-related diseases
  • Supports immune system function
  • Studied for cancer prevention properties in animal models
Side Effects
  • Headache (mild, dose-dependent)
  • Nausea (rare)
  • Well-tolerated overall in clinical trials
  • Injection site irritation (mild)
  • Temporary sleep changes during cycle (usually improves)
  • Rare: fatigue
