- Before selecting a peptide protocol, understanding mechanism, bioavailability, and clinical evidence is essential. Each peptide addresses distinct aspects of post-antibiotic damage.
- BPC-157
- VEGF upregulation, tight junction repair, NO pathway modulation
- Subcutaneous 250–500 mcg daily or oral gastric-resistant capsules
- Extensive animal models (rats, GI injury); human case reports; no Phase III trials
- Barrier recovery 7–14 days; full epithelial healing 21–28 days
- Gold standard for structural repair; limited human RCT data but strong mechanistic foundation
- Thymalin
- Thymic peptide signaling, Treg restoration, mucosal IgA recovery
- Intramuscular 5–10 mg every other day × 10 doses or subcutaneous 2–5 mg
- Clinical use in Russia/Eastern Europe for immune modulation; limited Western RCTs
- IgA rebound 14–21 days; immune rebalancing 28+ days
- Best choice for immune-mediated symptoms (food sensitivities, histamine intolerance); requires consistent dosing
- KPV
- NF-κB inhibition, mast cell stabilization, cytokine suppression
- Oral 500 mcg–1 mg daily or subcutaneous 200–500 mcg
- Inflammatory Bowel Diseases murine colitis studies; emerging human data
- Inflammation reduction 3–7 days; symptom relief (bloating, discomfort) within 5–10 days
- Most effective for acute inflammatory symptoms; short half-life requires split dosing
