Overview

Known for

Body Protection Compound. Derived from human gastric juice. Powerful healing peptide for tendons, ligaments, muscles, gut, and organs. Anti-inflammatory. Promotes angiogenesis and tissue repair. Most versatile healing peptide.

Mechanism

Gastric pentadecapeptide — derived from body protection compound found in gastric juice. Promotes angiogenesis, tendon/ligament healing, gut repair, neuroprotection.

Protocol

250-500mcg/day SubQ. Inject near injury site for localised effect or abdominally for systemic. Can split to 2x daily.

Time to effects

EARLY: 3-7 days

FULL: 4-8 weeks

Day 1-3: Some users report reduced pain/inflammation within days. This is one of the fastest-acting peptides.

Week 1-2: Noticeable pain reduction and improved mobility in injured areas. Gut healing improvements if used for GI issues.

Week 2-4: Significant healing progress. Range of motion improving. Tendon/ligament injuries showing measurable recovery.

Week 4-8: Major structural healing. Many injuries substantially resolved.

One of the few peptides where you can genuinely feel a difference within the first week. Minimum commitment: 4 weeks for injuries. 2-4 weeks for gut issues.

Recommended vial
  • 10mg vials

At 500mcg/day, 5mg = 10 days ✓, 10mg = 20 days ✓. Both work perfectly. 10mg for convenience, 5mg for maximum freshness.

Handle with research caution

  • Caution with NSAIDs (may reduce BPC-157 efficacy — use paracetamol instead)
  • Theoretical concern: may promote angiogenesis in existing tumours — avoid if active cancer/tumour history
