- BPC-157
- Zonulin downregulation; occludin/claudin-5 upregulation
- 250–500mcg daily, split AM/PM doses
- Enhances Lactobacillus colonization; reduces proteobacterial overgrowth
- 30–50% reduction in lactulose/mannitol ratio within 4 weeks
- Gold standard for structural barrier repair. Strongest evidence base for tight junction restoration
- KPV (5mg formulation)
- NF-κB inhibition; prevents cytokine transcription
- 500–1000mcg daily, single dose or divided
- Synergistic with butyrate-producing species (F. prausnitzii)
- 40–60% reduction in fecal calprotectin (inflammatory marker) within 6 weeks
- Best for acute inflammatory flares. Acts faster than BPC-157 but requires microbiome pre-conditioning for sustained effect
- Thymosin Beta-4
- GALT modulation; T-regulatory cell restoration
- 2–5mg weekly, subcutaneous
- Increases microbiome diversity by 15–25% within 8 weeks
- Restoration of CD4+/CD25+ T-reg populations to normal range
- Strongest immunomodulatory profile. Essential when autoimmune component is suspected
- Thymalin (bioregulator)
- Thymic peptide; GALT immune coordination
- 10mg every 10 days, intramuscular or subcutaneous
- Correlates with Akkermansia muciniphila abundance increases
- Normalized secretory IgA levels in mucosal tissue
- Underutilized in standard protocols. Particularly effective when combined with probiotic pre-loading
