BPC-157 in the Published Literature
Reviewed by our laboratory team · Last updated 2026-07-03
BPC-157 published literature spans approximately three decades and is largely authored by the Sikiric group at the University of Zagreb. Studies cover gastric protection, tendon and ligament repair, angiogenesis, muscle injury, and neurological injury animal models. Independent replication is limited.

How to access
PubMed searches for 'BPC-157' or 'pentadecapeptide BPC' return the primary literature. Reviews by Sikiric et al. in Current Pharmaceutical Design provide overviews.
Extended research context
The BPC-157 (Pentadecapeptide) deep dive
Deep dive: the pentadecapeptide sequence
BPC-157 is a synthetic pentadecapeptide with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. It is derived from a fragment identified in human gastric juice by the Zagreb research group (Sikirić and colleagues), whose body of published work spans three decades and covers models ranging from tendon repair to gut integrity. The 'BPC' initials stand for 'body protection compound' — the group's original characterisation term.
Two forms: acetate salt vs arginate
BPC-157 is supplied most commonly as an acetate salt; a small subset of suppliers offer the arginate form, which has slightly different solubility and stability properties. For research reproducibility, keep the salt form consistent across a study and confirm which form the CoA specifies (mass ± counterion changes the reading).
Reading a BPC-157 CoA
A trustworthy BPC-157 CoA lists HPLC purity (target ≥98% area), mass-spec confirmation (~1,419 Da for the free peptide), water content (Karl Fischer), acetate content, and residual solvents. Some batches also include endotoxin data. Any missing category is a red flag for a compromised supply chain.
Research applications
- ▸Cell-culture models of gut epithelial integrity
- ▸Tendon fibroblast migration and collagen-synthesis assays
- ▸Angiogenesis models involving VEGF and NO signalling
- ▸Stability studies comparing acetate vs arginate salt forms
- ▸Analytical reference for pentadecapeptide HPLC methods
Handling checklist
- ✓Store lyophilised vial at −20 °C long-term (2–8 °C short-term)
- ✓Reconstitute with bacteriostatic water; a 5 mg vial dissolves cleanly
- ✓Aliquot reconstituted solution; keep refrigerated 2–8 °C, use within 28 days
- ✓Protect from light and repeated warming
- ✓Verify CoA: HPLC ≥98%, mass ~1,419 Da, salt form declared
Common research-handling mistakes
Learnt from thousands of researcher orders across our UK labs.
✗ Mixing acetate and arginate BPC-157 across a study
Fix: Choose one salt form and stay with it — different masses and solubility.
✗ Assuming stability at room temperature
Fix: Refrigerate reconstituted solution; discard after 28 days.
✗ Buying without a CoA
Fix: Only source from suppliers that publish batch HPLC + mass-spec data.

- Peptide ReferenceWhat Are Peptides? Complete GuidePeptides are short chains of amino acids connected by peptide (amide) bonds. Typically fewer than 50 residues, they occupy the middle ground between single amino acids and proteins. Peptides serve as hormones, signalling molecules, structural fragments, and — increasingly — as research and therapeutic targets.
- Bacteriostatic WaterWhat Is Bacteriostatic Water?Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol inhibits bacterial growth after the vial's initial puncture, making the same vial suitable for repeated withdrawal in research handling. It is not the same as plain sterile water.
