Gut Health

Research compounds studied for gut lining repair, intestinal permeability reduction, and inflammatory bowel conditions. Many effective via oral route - no injections required.

Most researched for Gut Health

BPC-157

The most referenced gut healing peptide with a unique advantage: it survives digestion and acts directly on the gut lining when taken orally. Research shows accelerated healing of gastric ulcers, intestinal fistulas, and IBD-related damage. The oral route makes it the most accessible entry point for gut health research - no injections needed for gut-specific applications.

BPC-157

aka Body Protection Compound-157, PL 14736

Popular

How it works: Upregulates growth factor receptors and promotes angiogenesis to accelerate soft tissue repair.

Tendon, ligament, muscle, bone healing; GI tract repair; wound healing

Dosage range

200-500 mcg, Once or twice daily

Administration

SubQ / IM / Oral / Intranasal

Timing

Morning fasted or near injury site

Cycle length

4-12 weeks

KPV

aka Lys-Pro-Val, alpha-MSH C-terminal tripeptide

Moderate

How it works: Blocks NF-kB inflammatory signaling pathways to reduce chronic inflammation.

GI inflammation; IBD/Crohn's; leaky gut; systemic anti-inflammatory

Dosage range

250-1000 mcg, Once or twice daily

Administration

SubQ / Oral

Timing

Any time

Cycle length

4–8 weeks

Larazotide Acetate

aka AT-1001, Larazotide, AT-1001, INN-202

Moderate

How it works: Directly tightens intestinal tight junctions to reduce leaky gut and prevent passage of antigens.

Leaky gut reduction; celiac adjunct; intestinal barrier restoration

Dosage range

0.25-2 mg, 3×/day before meals

Administration

Oral

Timing

Before each meal

Cycle length

8–12 weeks

LL-37

aka Cathelicidin, Cathelicidin, CAMP

Moderate

How it works: An antimicrobial host defense peptide that kills pathogens directly and recruits immune cells to sites of infection.

Antimicrobial (bacteria, fungi, viruses); immune modulation; wound healing

Dosage range

0.1-1 mg, Variable; 1–3×/day or every other day

Administration

SubQ / Topical

Timing

Any time

Cycle length

4–8 weeks

BPC-157 Oral Capsules

aka Oral BPC-157, BPC-157 capsules

Moderate

How it works: Oral BPC-157 survives gastric acid (gastric protein origin); local GI mucosal effects + some systemic absorption; upregulates VEGF/EGF locally in GI; anti-inflammatory mucosal

GI tract healing (primary); gastric ulcer; IBD; leaky gut; esophageal repair

Dosage range

500-1000 mcg, Once or twice daily (oral)

Administration

Oral

Timing

Fasted for systemic attempt; with meals for GI mucosal targeting

Cycle length

4–12 weeks

VIP

aka Vasoactive Intestinal Peptide, Vasoactive Intestinal Peptide

Advanced

How it works: Binds VPAC1 and VPAC2 receptors; vasodilation; bronchodilation; immunomodulation (anti-inflammatory in some contexts); GI secretion; CNS neuroprotection; circadian regulation

POTS/dysautonomia (emerging); mast cell activation; pulmonary arterial hypertension (VPAC agonism); immune modulation

Dosage range

50-200 pmol/kg/min (IV); or 50–200 mcg SubQ, Variable by indication

Administration

SubQ / IV (clinical)

Timing

Any time

Cycle length

Per protocol

Example stacks

Beginner

Gut Health - Beginner

Oral BPC-157 is the most accessible gut healing protocol - no injection required. Survives digestion and acts directly on the gut lining.

Primary
BPC-157250 mcg/day - On empty stomach AM
  • Take on empty stomach - 30 min before food or 2 hrs after
  • Keep a symptom diary
  • Be patient - improvements start at 3-4 weeks
Intermediate

Gut Health - Intermediate

BPC-157 repairs the gut lining while KPV targets inflammatory signaling. Both oral - a fully injectable-free protocol.

Primary
BPC-157250 mcg/day - Empty stomach AM
Support
KPV250 mcg/day - With or without food
  • Take BPC-157 fasted and KPV any time
  • KPV is especially useful for IBD and autoimmune component
  • Eliminate known dietary triggers
