WHAT IS BPC-157?
Detailed overview
BPC-157 (Body Protection Compound-157) is a synthetic 15-amino-acid peptide isolated from a protein in human gastric juice (BPC). It shows outstanding regenerative effects in tendons, muscles, neural tissue, the gastrointestinal tract and bone. At the molecular level it modulates VEGF expression (angiogenesis), the NO system (vascular tone) and the FAK-paxillin signalling pathway (cell migration). More than 30 years of research, primarily animal data.
Type
15-amino-acid pentadecapeptide
Structure
Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
Molecular weight
~1419 Da
Target area
Tendon, muscle, GI tract, nerve
Storage
2–8°C (reconstituted)
Stability
25–30 days (reconstituted)
Tissue regeneration
Tendons, muscles, ligaments, GI mucosa and skin heal faster thanks to direct cell-level signaling: it activates fibroblast migration, angiogenesis (VEGF pathway) and reduces pro-inflammatory cytokines (IL-6, TNF-α). Chronic, slow-healing injuries see functional improvement; pain and swelling drop. Post-workout recovery windows shorten by 30–50%, allowing more training volume. Effects are documented even in enthesopathy, tendinitis and GI ulcers.
GI tract protection
Directly stimulates gut-mucosal regeneration: epithelial renewal, tight-junction restoration, mucosal thickness normalization. In inflammatory bowel disease (Crohn, UC) symptom reduction and improved clinical activity index are documented. In functional GI disorders (IBS, FD) bloating, pain and discomfort drop. Also effective in preventing NSAID-induced gastropathy and stress ulcers. Microbiome-friendly anti-inflammatory profile.

Reconstitution
How to prepare, step by step
Important
Sterile technique required. Use bacteriostatic water (BAC) only. Never distilled or tap water.
- 01
Remove the vial and bacteriostatic water (BAC) from refrigeration; let them reach room temp for 5 minutes.
- 02
Wipe both vial stoppers with an alcohol swab.
- 03
Draw 2 ml of BAC water into a sterile syringe (typical for the 5 mg vial).
- 04
Inject slowly down the side of the vial, do NOT spray directly onto the peptide powder.
- 05
Swirl gently in a circular motion until dissolved (~30 s), do not shake.
- 06
Wait for the solution to become clear. If sediment or discoloration appears, discard it.
- 07
Label the vial with reconstitution date and concentration.
- 08
Store at 2–8 °C, protected from light. Inspect visually before each use.
