The BPC-157 Reference

BPC-157 (also written BPC 157, BPC157, or Body Protection Compound 157) is a synthetic pentadecapeptide consisting of 15 amino acids (sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val). It was originally derived from a larger gastric protective protein fragment isolated from human gastric juice by Sikiric and colleagues in 1993.

BPC-157 is not a ballpoint pen, writing implement, or office supply. It is a peptide compound. The term BPC-157 peptide pen refers to a pre-filled delivery device, not a writing instrument.

The full chemical name is body protection compound 157, with the historical clinical-trial designation PL14736 from early Pliva-sponsored work on inflammatory bowel disease. The peptide has a molecular mass of approximately 1419.5 Da and is unusually stable in acidic environments, which is part of why the original Zagreb group characterised it as a candidate gastric cytoprotectant.

BPC-157 has no marketing authorisation as a pharmaceutical in any jurisdiction. The historical PL14736 designation reflects early-phase clinical trial work on inflammatory bowel disease that did not progress to approval. It is supplied as a research peptide for laboratory use only.

How BPC-157 differs from TB-500

BPC-157 and TB-500 are both research peptides studied for tissue-repair applications, but they are structurally and mechanistically distinct. BPC-157 is a pentadecapeptide (15 residues) derived from a human gastric protein fragment. TB-500 is a synthetic fragment of thymosin beta-4, a 43-amino-acid peptide. The two are frequently studied in combination; see the BPC-157 and TB-500 combination reference at /uae/guides/bpc-157-tb-500.

Why BPC-157 is written as BPC-157, BPC 157, or PL14736

Four variant spellings appear across the literature and commercial sources. Each refers to the same compound.

The biological activity of BPC-157 in preclinical research is described across four principal mechanistic threads. None of these have been characterised in human clinical trials beyond early-phase work, and the dominant evidence base is rodent models.

Tendon and ligament research findings

Krivic and colleagues (J Orthop Res, 2006;24(5):982-989) examined BPC-157 in a rat Achilles tendon-to-bone detachment model. The published findings reported promoted tendon-to-bone healing in BPC-157-treated rats and a counter-effect against corticosteroid-induced aggravation of healing impairment.

Cerovecki and colleagues (J Orthop Res, 2010;28(9):1155-1161) extended the model to medial collateral ligament transection in rats. The published findings reported improved biomechanical properties of healing ligament tissue in BPC-157-treated subjects compared with controls.

Cellular mechanism in tendon fibroblasts

Chang and colleagues (J Appl Physiol, 2011;110(3):774-780) characterised BPC-157 effects on tendon fibroblast cultures. The published findings reported dose-dependent increases in cell migration, dose-dependent increases in survival under hydrogen peroxide stress, and corresponding increases in FAK and paxillin phosphorylation. The work provides a candidate cellular mechanism for the macroscopic tendon healing findings.

GI tract and inflammatory bowel disease research

Klicek and colleagues (J Pharmacol Sci, 2008;108(1):7-17) characterised BPC-157 effects in a rat colocutaneous fistula model. The published findings reported accelerated fistula closure and direct dependence on the nitric oxide system, demonstrated by L-NAME (an NO synthase inhibitor) and L-arginine co-treatment. The compound was tested in this work under the PL14736 clinical-trial designation.

All effects described in this section have been observed in preclinical research models, predominantly rodent. None constitute therapeutic claims or clinical findings.

BPC-157 appears across four principal research application areas in the published literature. The dominant evidence base is rodent and in vitro studies; no large-scale human clinical trial data has been published outside the early-phase PL14736 work.

Musculoskeletal tissue repair research

The most heavily published preclinical application area outside the GI tract. Investigators study BPC-157 in tendon, ligament, muscle, and tendon-to-bone insertion injury models. The compound serves as a research benchmark for probing tissue-repair pathways across rodent acute injury designs.

Gastrointestinal research

The original research area and the basis for the compound's Body Protection Compound name. BPC-157 has been examined in gastric mucosal protection models, intestinal anastomosis healing, fistula closure (the PL14736 work), and inflammatory bowel disease models. Sikiric and colleagues at the University of Zagreb have driven the bulk of the published GI work.

Vascular and angiogenesis research

Preclinical models report effects on vascular endothelial growth factor signalling and microvessel formation. The angiogenic response is the candidate mechanism most often invoked to explain the cross-tissue repair effects observed across the BPC-157 literature.

Central nervous system research

Rodent studies have examined BPC-157 interaction with the dopaminergic and serotonergic systems in models of CNS injury and neurotransmitter pathway perturbation. This research area is less extensively documented than the GI and musculoskeletal work and remains preclinical.

A research peptide pen is a factory-sealed, pre-filled delivery device supplied ready to use at a fixed concentration, with no reconstitution or mixing step at the point of use. The format originated in clinical injection devices and has been adapted for research handler use where dose consistency across experiments matters more than per-experiment flexibility.

The pen format differs from the lyophilised vial format in three practical ways. Pens arrive ready to use with no reconstitution step. The seal limits airborne contamination during repeated draws. The graduated dose mechanism provides volume consistency that is difficult to match with a manual draw from a stoppered vial.

A pen fixes the concentration set at manufacture, which suits a single-concentration study or a series of replicates at the same dose and reduces handler variance. For in vitro assays that call for a range of working concentrations, researchers derive those from the fixed-concentration stock in the laboratory.

The Baseline BPC-157 product is supplied as a BPC-157 and TB-500 combination pen, the combination most frequently studied in tissue-repair research designs. See the combination reference for the rationale.

The quality of BPC-157 is defined by the documentation that accompanies it. A peptide with a published synthesis route but no batch-specific Certificate of Analysis is not a research material; it is an unknown. Researchers procuring BPC-157 in the UAE or anywhere else should expect the following at minimum.

• HPLC purity greater than 98 percent, ideally above 99 percent for sensitive research applications.
• Mass spectrometry confirmation of the BPC-157 pentadecapeptide sequence and molecular mass (1419.5 Da).
• Batch-specific Certificate of Analysis from an independent third-party lab, not just an in-house result.
• Endotoxin testing where the material is intended for cell culture or animal research.
• Documented cold-chain handling from synthesis through shipping, with temperature logs available on request.

For the Baseline BPC-157 and TB-500 combination pen, the per-batch lab report is published at /uae/peptides/bpc157-tb500-32. The CoA documents HPLC purity, mass spectrometry confirmation of both peptide sequences, and the in-house concentration assay. Independent third-party reports are available on request.

If there is no CoA, there is no peptide. Only powder.

Research peptides are not pharmaceuticals under UAE Federal Decree-Law No. 38 of 2024 and are not regulated as medicines. BPC-157 is not an approved medicine and is only ever considered after a consultation. Your consultant reviews your history first, and you are monitored throughout.

Cold-chain handling matters more in the Gulf than almost anywhere else. Summer ambient temperatures routinely exceed the stability window for these compounds, so where a program is running the chain from storage to delivery is our responsibility rather than a courier’s.

Cold-chain shipping in the GCC requires considered packaging. Ambient temperatures across the summer months routinely exceed 40 degrees Celsius, well above the stability window for research peptides. See the dedicated reference at peptide delivery and GCC cold chain for the operational considerations.
