BPC-157 research: a summary of the published literature

What “BPC” stands for and where the sequence comes from

BPC is short for Body Protection Compound. BPC-157 is a 15-amino-acid synthetic peptide (a pentadecapeptide) drawn from a partial sequence of a gastric-juice protein described in the body protection compound literature. The “157” refers to the specific residue stretch of the parent sequence used for the synthetic peptide.

Structure and physicochemical data

Standard chemistry databases record the following identity values for BPC-157. The dedicated reference page for the molecule is BPC-157.

Publication landscape

The PubMed query "BPC 157" OR "pentadecapeptide BPC 157" returns the current indexed set of BPC-157 publications. The literature is concentrated in two ways:

• By year. Most publications appear from the mid- 2010s onward; the annual breakdown on PubMed is the authoritative count. This page does not quote a frozen year-by-year table because that count moves.
• By author group. A substantial fraction of the published BPC-157 literature is produced by the research group of P. Sikiric and colleagues at the University of Zagreb, who introduced the pentadecapeptide form of BPC-157 and have continued to publish on it.
• By study type. The published set is dominated by in vitro work and animal (mostly rodent) studies. Human-registered clinical studies are a small share; the current list on ClinicalTrials.gov is the authoritative source.

Study designs used

• In vitro experiments on cell lines or primary cells, usually with the peptide added to the culture medium at a stated concentration range.
• Rodent models, including rat and mouse studies. Routes of administration are described in the published work as experimental variables; this page does not reproduce any such route or quantity as a use instruction.
• Analytical and pharmacokinetic reports that describe how BPC-157 is measured in a specified matrix (plasma, tissue homogenate, buffer).

Stability and half-life data in the literature

Published pharmacokinetic reports describe BPC-157 degradation under physiological conditions and measurement by HPLC and LC-MS/MS. The reported half-life figure depends on the matrix (serum, plasma, tissue homogenate, buffer), the species, and the assay used, so a single universal number does not apply. For the current set of pharmacokinetic reports, filter the PubMed query above by publication type or by keywords such as “pharmacokinetics” or “LC-MS/MS”. See the peptide storage overview for the general stability framing.

Analytical methods used in published work

Published BPC-157 analytical workflows typically combine:

• Reversed-phase HPLC with UV detection (commonly at 214 nm or 220 nm for the peptide bond) for purity and quantitation in a defined matrix.
• Mass spectrometry, in particular LC-MS/MS, for identity confirmation and for quantitation in biological matrices.

The purity testing methods explainer describes each method at the level that appears on a research-peptide certificate of analysis.

Limitations of the evidence

• Preclinical weighting. The large majority of BPC-157 publications are in vitro or animal studies. Human- registered studies are a small share. Findings in a rodent model do not transfer to humans.
• Author concentration. A substantial fraction of the literature is produced by one research cluster (University of Zagreb group). Independent replication across other groups is narrower than for established drugs.
• Context-specific findings. Each published number applies to the matrix, species, model and assay it was reported in, not to the peptide in general and not to any human use.
• No regulatory approval. BPC-157 is not an approved drug. It is a research chemical.
