Thymosin Alpha-1 Upregulates T-regulatory cells, modulates Th1/Th2 balance TGF-beta1, autoimmune signaling 0.75–2mg per injection Subcutaneous 2–3x weekly for 8–12 weeks Best first-line peptide for immune dysregulation; measurable TGF-beta1 reduction in 60–70%

  • Thymosin Alpha-1
  • Upregulates T-regulatory cells, modulates Th1/Th2 balance
  • TGF-beta1, autoimmune signaling
  • 0.75–2mg per injection
  • Subcutaneous
  • 2–3x weekly for 8–12 weeks
  • Best first-line peptide for immune dysregulation; measurable TGF-beta1 reduction in 60–70% of patients
  • BPC-157
  • Promotes angiogenesis, stabilizes nitric oxide, accelerates mucosal healing
  • Zonulin, gut permeability, VEGF
  • 250–500mcg daily
  • Subcutaneous or oral
  • Once daily for 4–8 weeks
  • Critical for patients with gut symptoms; oral dosing less studied but used clinically for localized GI repair
  • KPV
  • Inhibits NF-kappaB, mimics alpha-MSH anti-inflammatory effects
  • MSH deficiency, TNF-alpha, IL-6
  • 500mcg–1mg per dose
  • Subcutaneous or intranasal
  • 1–2x daily for 6–12 weeks
  • Addresses MSH deficiency without receptor desensitization; intranasal route bypasses first-pass metabolism
  • LL-37
  • Antimicrobial peptide, modulates immune response to bacterial/fungal antigens
  • MMP-9, bacterial translocation
  • 1–2mg per injection
  • 2–3x weekly for 6–8 weeks
  • Studied in chronic infection contexts; less CIRS-specific evidence but used for co-infections (Lyme, Bartonella)
