Larazotide Acetate
Summary
Prostamax is a tetrapeptide bioregulator (Lys-Glu-Asp-Pro) developed by Professor Vladimir Khavinson, tissue-specific for the prostate gland. It supports prostate epithelial cell function, promotes normalization of prostate tissue, and is studied for its potential in benign prostatic hyperplasia (BPH), prostatitis, and prostate anti-aging. It is one of the more widely used Khavinson bioregulators among men over 40.
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.

Key Benefits
  • Supports normalization of prostate tissue architecture
  • May reduce prostate enlargement associated with BPH
  • Anti-inflammatory effects on prostatic tissue
  • Reduces prostate cell apoptosis from oxidative stress
  • Potential support in chronic prostatitis
  • Anti-aging effects on prostate glandular tissue
  • Complementary to conventional BPH therapies
  • 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
Side Effects
  • Generally well tolerated in available research
  • Mild injection site reactions
  • No significant adverse urological events reported at standard doses
  • Headache (mild, dose-dependent)
  • Nausea (rare)
  • Well-tolerated overall in clinical trials
