Research peptides for gut lining repair and digestive health - BPC-157, larazotide, KPV and oral peptide protocols.
A pentadecapeptide derived from human gastric juice that promotes wound healing and tissue repair. Demonstrates remarkable regenerative properties across multiple tissue types including tendon, muscle
Dose: 250-500 mcg per dose | Route: Subcutaneous injection (or oral capsules)
A tripeptide derived from alpha-MSH with potent anti-inflammatory properties. Shows promise for gut inflammation, skin conditions, and immune modulation without melanogenic effects.
Dose: 200-500 mcg per dose | Route: Oral, topical, or subcutaneous
A first-in-class tight junction regulator designed to reduce intestinal permeability ("leaky gut"). Originally developed for celiac disease, now researched for broader applications in autoim
Dose: 0.5-1 mg | Route: Oral capsule
A human cathelicidin antimicrobial peptide with broad-spectrum activity against bacteria, viruses, and fungi. Also promotes wound healing and modulates innate immune response.
Dose: 50-100 mcg | Route: Topical or subcutaneous injection
The first milk produced after birth, rich in immunoglobulins (IgG), growth factors (IGF-1, TGF-β), lactoferrin, and proline-rich polypeptides. Supports gut barrier integrity, immune function, and muco
