- Thymalin
- T-regulatory cell restoration; reduces mast cell hypersensitivity through immune recalibration
- 3–6 weeks for sustained effect
- 10mg SC twice weekly × 8 weeks
- Phase 2 clinical data in MCAS populations
- Best for systemic immune-driven histamine intolerance with elevated tryptase
- KPV
- NF-κB inhibition; direct mast cell membrane stabilization preventing degranulation
- 24–48 hours for acute symptom reduction
- 500mcg–1mg SC daily
- Preclinical models + case series
- Best for flare management and gut-specific histamine symptoms
- BPC-157
- Gut barrier repair via VEGF upregulation; reduces intestinal permeability to dietary histamine
- 14–21 days for barrier restoration
- 250–500mcg SC twice daily
- Extensive animal models; limited human RCTs
- Best when food triggers dominate and lactulose-mannitol testing shows leaky gut
- The table shows peptides addressing different failure points in histamine regulation. Thymalin targets upstream immune dysfunction. The reason mast cells are hyperreactive in the first place. KPV works at the mast cell itself, preventing degranulation regardless of trigger exposure. BPC-157 addresses downstream consequence. The compromised gut barrier that allows triggers into circulation. Effective protocols often combine two peptides: thymalin for immune recalibration plus KPV during acute flares, or BPC-157 for barrier repair plus KPV for symptom control during the repair window.
