Larazotide Acetate vs SNAP-8

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

Skin & Cosmetic
SNAP-8
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.
SNAP-8 is a synthetic octapeptide cosmetic ingredient that reduces the depth of expression lines and wrinkles by competitively inhibiting the SNARE complex involved in acetylcholine release at neuromuscular junctions, providing a topical 'Botox-like' effect.
Half-Life

N/A — topical application; local effect duration depends on formulation
Admin Route
Oral
Topical
Research
Typical Dose
0.5-2 mg
3–10% concentration in formulation
Frequency
3x daily
1–2x 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
  • Reduces depth of dynamic expression wrinkles
  • Smooths forehead lines, crow's feet, glabellar lines
  • Non-invasive topical Botox alternative
  • Can be incorporated into serums, creams, eye contour products
  • Reduces muscle contraction without paralysis
  • Improves skin texture and firmness over time
  • Complements other anti-aging peptides (Argireline, Matrixyl)
Side Effects
  • Headache (mild, dose-dependent)
  • Nausea (rare)
  • Well-tolerated overall in clinical trials
  • Generally excellent tolerability
  • Rare: mild redness in sensitive individuals
  • Not suitable for injection (topical use only)
