BPC-157: The Body Protection Compound

BPC-157 (Body Protection Compound-157) is a 15-amino-acid peptide derived from a protective protein found in human gastric juice. It is one of the most extensively studied peptides in the healing category, with over 100 published studies demonstrating remarkable tissue repair properties across virtually every tissue type tested. BPC-157 promotes healing through multiple mechanisms: upregulation of growth factor receptors (particularly VEGF and EGF), nitric oxide system modulation, enhanced angiogenesis (new blood vessel formation), and direct anti-inflammatory effects through TNF-alpha and IL-6 reduction.

Dosing for BPC-157 typically ranges from 250mcg to 500mcg per day, administered subcutaneously. For localized injuries (tendon tears, joint damage, muscle strains), injecting as close to the injury site as possible produces the most pronounced local healing effect. For systemic benefits including gut healing, anti-inflammatory effects, and neuroprotection, subcutaneous injection in the abdominal area is standard. Many practitioners split the daily dose into two administrations (morning and evening) to maintain more consistent blood levels given BPC-157's relatively short half-life of approximately 4 hours.

One of BPC-157's most notable properties is its effect on gut permeability. Clinical experts frequently cite it as the single most important peptide for addressing the gut-inflammation axis that drives systemic inflammation (Root Cause 1). BPC-157 has been shown to accelerate healing of gastric ulcers, reduce intestinal inflammation, and restore tight junction proteins that maintain the gut barrier. This gut-healing property makes it a foundational compound in the Three Root Causes framework, as resolving gut permeability is often the first step in breaking the inflammatory arm of the death spiral.
