Gut Health & Anti-Inflammation Protocol
A multi-tiered protocol targeting gut repair, barrier function, and anti-inflammatory pathways using BPC-157, KPV, TB-500, GHK-Cu, and Larazotide.

Overview
The primary research peptides that are commercially available (via research chemical suppliers in vial or stabilized capsule form) and have been studied for gut repair, barrier function, anti-inflammatory effects, and related conditions (e.g., leaky gut, IBS, IBD models) are these five. These are the compounds consistently referenced across sources for these specific goals.
The Five Key Peptides
1. BPC-157 (Body Protection Compound-157)
Derived from gastric juice; promotes gut lining repair, angiogenesis, and reduces inflammation. Strongest evidence for ulcers, leaky gut, and IBD-like models. Available as oral capsules (stable arginate salt) or injectable.
2. KPV (Lys-Pro-Val, fragment of α-MSH)
Potent anti-inflammatory tripeptide; calms NF-κB/cytokine pathways, supports intestinal mucus barrier and microbiome balance. Excellent for gut-specific inflammation. Available oral or injectable.
3. TB-500 (Thymosin Beta-4 fragment)
Enhances cell migration, actin regulation, and systemic tissue repair; reduces inflammation and scarring. Complements gut healing with broader recovery. Primarily injectable (not orally bioavailable).
4. GHK-Cu (Glycyl-L-histidyl-L-lysine copper complex)
Modulates inflammation, stimulates collagen/extracellular matrix repair, and supports antioxidant balance. Adds skin/gut regeneration benefits. Injectable or topical; copper can interact with other peptides if mixed long-term.
5. Larazotide (Larazotide acetate)
An 8-amino-acid synthetic peptide and tight-junction regulator (zonulin antagonist); specifically targets intestinal permeability (“leaky gut”). Studied in celiac and permeability models. Oral capsule form.
These are the peptides sold in research blends (e.g., BPC-157 + KPV + TB-500 + GHK-Cu “Klow/Glow” blends or oral gut capsules combining BPC-157 + KPV + Larazotide). Other peptides (e.g., Thymosin Alpha-1 for immune modulation) exist but are less directly tied to gut/inflammation repair in the literature.
Recommended Protocol Options
Choose based on your goals and tolerance. Gut-focused protocols prioritize oral forms for direct intestinal delivery. Start low, monitor response, and use pharmaceutical-grade reconstitution (bacteriostatic water) for injectables. Typical cycle: 4–8 weeks on, followed by 2–4 weeks off. Pair with a clean anti-inflammatory diet, stress management, and probiotics.
Option 1: Minimal Effective Stack (2 Peptides) — Best starter for pure gut issues
- BPC-157: 250–500 mcg oral capsule once or twice daily (empty stomach).
- KPV: 250–500 mcg oral capsule daily (often combined with BPC-157 in one capsule for convenience).
Why? Synergistic gut-lining repair + inflammation control. Many oral “gut inflammation” blends use exactly this pair.
Duration: 4–6 weeks.
Option 2: Balanced Healing Stack (3 Peptides) — Gut + mild systemic inflammation
- Keep BPC-157 + KPV oral as above.
- Add TB-500: 1–5 mg subcutaneous injection, 2–3 times per week (e.g., 1 mg every other day for the first 4 weeks).
Why? TB-500 amplifies tissue repair and reduces broader inflammation without daily injections.
Option 3: Comprehensive Recovery Stack (4 Peptides) — Most common advanced option
- BPC-157: 250–500 mcg oral daily.
- KPV: 250–500 mcg oral daily.
- TB-500: 1–5 mg subQ, 2–3×/week (1 mg EOD for first 4 weeks).
- GHK-Cu: 1–2 mg subQ once daily (can be mixed with TB-500 or BPC-157 in the same syringe if fresh; some prefer separate to avoid copper degradation of other peptides).
Why? Full-spectrum: gut repair (BPC/KPV), systemic healing/anti-inflammatory (TB-500), plus collagen/antioxidant regeneration (GHK-Cu). Widely used in research recovery protocols.
Administration note: Oral peptides first thing in the morning; injectables in the evening or post-workout. Rotate injection sites (abdomen/thigh).
Option 4: Maximum Gut-Barrier Stack (5 Peptides) — For severe leaky gut/permeability focus
Use the 4-peptide stack above + Larazotide: 0.5–1 mg oral capsule 1–3 times daily before meals.
Why? Larazotide directly tightens junctions while the others repair and calm inflammation. Some suppliers offer pre-made oral capsules with BPC-157 + KPV + Larazotide.
Additional Guidance
- Reconstitution & Storage (injectables only): Follow vial instructions (typically 2–3 mL bac water for standard 5 mg vials). Refrigerate reconstituted peptides; use within 30 days.
- Monitoring: Track symptoms (bloating, stool quality, energy, inflammation markers if lab-tested). Discontinue if any adverse effects occur.
- Synergies & Enhancers: These stack well with L-glutamine, zinc, or butyrate (non-peptide supports), but avoid NSAIDs/alcohol during use.
- Sourcing Note: Available only from licensed research peptide suppliers as research chemicals. Quality varies — third-party testing is essential.
This protocol is flexible; adjust based on professional guidance. The 4-peptide stack (BPC-157 + KPV + TB-500 + GHK-Cu) is the most frequently referenced combination for balanced inflammation and gut health in available research contexts.
