If you have been reading about gastric juice protein and want a single page that covers the useful parts, this is it: definitions, context, how it is studied, and the questions that come up repeatedly.
Updated 2026-08-01. Numbers and descriptions here follow the published literature rather than marketing material.
Most published findings come from rodent experiments using induced injury or surgical models. Human reports remain scarce and are largely observational, which limits how much can be stated with confidence. Questions about absorption, distribution, metabolism, and clearance in people are still open. Dose translation between species is likewise unresolved. Researchers tend to read the animal literature as a starting point rather than a settled account.
BPC-157 is a synthetic peptide composed of fifteen amino acids. Its sequence corresponds to part of a protein found in human gastric juice, which is the origin of the "body protection compound" label. In laboratory work the material is treated as a defined research chemical rather than a finished product. Published research has centered on animal models, and the peptide is not an approved medicine in most countries.
The peptide was first described in the early 1990s by a group studying gastric secretions and tissue repair. Its fifteen-residue chain is usually written as GEPPPGKPADDAGLV in single-letter code. The free peptide has the formula C62H98N16O22 and a theoretical mass near 1419.5 daltons. These identifiers are established chemical facts that can be checked against standard peptide databases. There is no ambiguity about the primary structure.
Lyophilized material is generally reported as stable for extended periods when kept cold, dry, and protected from light. In solution, the main degradation routes for a peptide of this type are hydrolysis of peptide bonds and aggregation. The sequence contains no cysteine, so disulfide-driven oxidation is not a primary concern, though methionine and tryptophan are also absent. Stability depends on pH, buffer composition, and concentration, with acidic conditions often reported as more favorable than neutral or alkaline ones. Repeated freeze-thaw cycles can promote aggregation, and how fast degradation proceeds at room temperature in specific formulations remains an open question.
Handling practice centers on limiting moisture, heat, and mechanical stress. Powder is typically allowed to reach room temperature before opening so that condensation does not form on the contents, and solutions are prepared with sterile or low-particulate water. Peptides can adsorb to certain plastics and membrane filters, so container and filter material is sometimes specified to reduce losses at low concentrations. Working aliquots are usually frozen separately rather than sampled repeatedly from one stock. Recording lot number, preparation date, and storage conditions supports later comparison between experiments.

Published studies on BPC-157 are dominated by animal models. Commonly used endpoints include healing of surgically induced lesions in the stomach, tendon-to-bone attachment after transection, and recovery from experimentally induced vascular or intestinal damage. Many of these reports come from a small number of research groups, and the peptide is often described as acting across a wide range of tissue types. That breadth is itself a point of discussion, since one molecule influencing many unrelated systems is unusual.
Human data are far more limited than animal data. A small number of clinical reports exist, generally with few participants and without the randomization or blinding expected in later-phase trials. No large, independently replicated human trial has appeared in the indexed peer-reviewed literature. Statements about effects in people therefore rest on extrapolation from animal work rather than on direct evidence, and the strength of that extrapolation remains an open question rather than a settled matter.
BPC-157 is commonly supplied as a lyophilized powder, a freeze-dried solid that is reconstituted before use in laboratory work. As a short peptide, it dissolves readily in water and in aqueous buffer solutions, and stock solutions are typically prepared in water or a mild buffer. The chain contains several proline and acidic residues, which influence how it behaves in solution. Because the solid can take up moisture, weighing and handling are usually performed under low-humidity conditions. Its solubility class is described as freely soluble in water rather than requiring an organic solvent.
Dry powder is generally stored at low temperature, with minus twenty degrees Celsius or colder advised for extended retention. Reconstituted solutions are less stable than the solid form and are normally kept cold and shielded from repeated freeze-thaw cycles. Light exposure is avoided because some peptides degrade under ultraviolet radiation. The exact rate of degradation depends on concentration, pH, and the presence of salts, so a single shelf life does not apply to every preparation. Reported stability figures should be read as indicative of typical handling rather than as universal constants.
Confirmation of identity and purity relies on standard peptide analysis techniques. Reverse-phase high-performance liquid chromatography separates the peptide from related impurities and serves as the most common purity assay. Mass spectrometry, often coupled to that chromatography step, provides an accurate molecular mass that can be matched against the expected value. Amino acid analysis or sequencing can be added for further confirmation. Because short peptides can be produced by different synthetic routes, laboratories usually report both a chromatographic purity percentage and a mass confirmation rather than a single figure.

== Contraindications == Pioglitazone cannot be used in patients with a known hypersensitivity to pioglitazone, other thiazolidinediones or any of the components of its pharmaceutical forms. It is ineffective and possibly harmful in diabetes mellitus type 1 and diabetic ketoacidosis. Its safety in pregnancy, lactation (breastfeeding) and people under 18 is not established. Given previous experiences with the related drug troglitazone, acute diseases of the liver are regarded as a contraindication for pioglitazone.
Prior to the 2018 reforms, the People's Armed Police Hydropower Corps (Chinese: 武警水电部队) was a specialist corps of the People's Armed Police. After the 2018 reforms, it was reorganised into the China Anneng Construction Group (中国安能建设集团), a state owned corporation for construction and disaster relief. Prior to 2018, the Hydropower Corps was in charge of managing, constructing and providing law enforcement to hyrdropower facilities along with flood management.

== Tributes == "Referring to the death of Professor Brailsford Robertson yesterday, the Prime Minister (Mr. Scullin) said:— His untimely end has robbed Australia of a brilliant scientist, whose contribution to the Commonwealth's progress would always be remembered. On behalf of the Federal Ministry Mr. Scullin extended his sincere sympathy to Professor Robertson's family, and expressed its appreciation of the great national services which he had rendered." The Argus, 20 January 1930. "Professor Brailsford Robertson was one of Australia's most brilliant scientists. The value of the work he was accomplishing cannot be estimated." Hon. R.L. Butler, Premier of South Australia, 20 January 1930. "The main purpose of [Robertson's] studies was to solve the mystery of physical life in it successive stages of commencement, growth, decline, and cessation, for the benefit of his fellow-men. ... The amount of original work he accomplished in his short life was prodigious. I would be rash to assert that the loss to science, or as I should prefer to say, the loss to humanity, caused by his death is irreparable, but it will probably be a long time before anyone else is able to gather the threads together and produce the fabric he was attempting to weave on his loom." Sir George Murray, Chancellor of the University of Adelaide, 18 March 1932.

The peptide is synthetic, but its sequence matches a segment of a protein present in human gastric juice. It does not occur as a free fifteen-residue peptide in the body.
Rodents account for the large majority of published experiments. Human data are sparse and mostly observational, so cross-species extrapolation remains uncertain.
It is not an approved therapeutic in most jurisdictions. Regulatory status varies by country, and several places restrict it as a research chemical.
Reversed-phase liquid chromatography with ultraviolet detection gives a purity estimate, while mass spectrometry confirms molecular mass and flags modifications. Amino acid analysis can add compositional confirmation. Results are most meaningful when a validated reference standard is run alongside the sample.
