A healing compound originally found in stomach juice. It's one of the most versatile peptides out there -- great for repairing damaged tissue, healing the gut lining, and calming down inflammation. Arguably the most well-studied healing peptide available.
What to Expect
Week 1–2
Reduced inflammation and pain at injury site. Mild improvement in gut symptoms if taken orally. Some users report faster wound closure.
Week 3–6
Noticeable tissue repair — tendons feel stronger, joint pain diminishes. Gut lining healing becomes apparent with reduced bloating and food sensitivities.
Week 8+
Significant structural repair of tendons, ligaments, and gut mucosa. Chronic injuries may reach full recovery. Benefits tend to plateau after 8-12 weeks.
Common Side Effects
Scientific Overview
Body Protection Compound-157 is a synthetic pentadecapeptide (15 amino acids) derived from human gastric juice protein BPC. It operates through multiple mechanisms including upregulation of growth factor expression (EGF, HGF, VEGF), activation of the FAK-paxillin pathway promoting angiogenesis, and modulation of the nitric oxide (NO) system. Studies demonstrate cytoprotective activity across gastrointestinal, musculoskeletal, and neurological tissues. BPC-157 has shown particular efficacy in tendon-to-bone healing models, where it accelerates collagen organization and mechanical strength recovery.
Dosing
250-500 mcg once or twice daily. Inject subq near the injury site, or take it orally if you're targeting gut issues. Typical cycle is 4-6 weeks.
Practical Guide
Reconstitution
Mix 5mg vial with 2mL bacteriostatic water (BAC water). Each 0.1mL = 250mcg.
Storage
Refrigerate after reconstitution. Use within 30 days. Store lyophilized powder at room temperature or refrigerated.
Injection Sites
Inject as close to the injury as possible for localized effects. Use 29-31g insulin syringe. Rotate injection sites.
Timing
Twice daily dosing (morning and evening) provides best coverage. No specific time-of-day preference.
Food
No significant food interactions for injectable. Oral capsules best taken on empty stomach for gut-targeted effects.
