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.
Last reviewed on 2026-04-24. Where a claim depends on a specific study, the study is described rather than over-claimed.
The sequence contains an unusually high proportion of proline and glycine, which limits regular secondary structure and contributes to solubility in aqueous media. The compound dissolves readily in water and in normal saline. Because it is a peptide, digestive enzymes are expected to break it down if it is swallowed, a consideration that influences the routes of administration used in animal experiments. Detailed conformational data remain limited, and published structural models are largely computational.
BPC 157 is a synthetic peptide built from fifteen amino acids. The letters stand for body protection compound, and the number is a laboratory code rather than a description of any biological feature. Its single-letter sequence is GEPPPGKPADDAGLV, which corresponds to a calculated mass near 1419.5 daltons. The material is produced by solid-phase peptide synthesis and is distributed as a lyophilized powder, not as a purified extract from a natural source.
Interest in the peptide has grown through online communities that discuss self-administered use, which sits outside formal research settings. Regulatory status varies by country, and in many jurisdictions the compound is not approved as a therapeutic product. Questions about optimal routes of administration, long-term effects, and dose-response relationships remain open. Published pharmacokinetic data in humans are limited, and much of what circulates in popular discussion is extrapolated from animal work rather than measured directly in people.
BPC-157 is a synthetic peptide built from fifteen amino acids, referred to in the literature as a pentadecapeptide. Its sequence was derived from a larger protein found in human gastric juice, commonly called body protection compound. Researchers first described the fragment in the early 1990s and named it after the parent protein plus a numeric identifier. The peptide does not correspond to a single marketed medicine; it is primarily a laboratory research material. Suppliers distribute it as a lyophilized powder intended for experimental use.

Most published work on BPC-157 consists of preclinical studies, including rodent models of tissue injury, gastrointestinal lesions, and vascular or tendon damage, together with in vitro cell assays. Reviews frequently note that the mechanisms proposed in these papers remain incompletely characterised and that findings have not been confirmed in large randomised human trials. The compound is widely sold as a research chemical rather than a licensed medicine, and labels commonly carry a statement that it is not for human use. Whether any of the reported animal effects translate to humans is an open question rather than an established result.
Terminology in the literature is not fully standardised. Papers and product listings use BPC-157, BPC 157, and the longer phrase stable gastric pentadecapeptide BPC 157 interchangeably, and synonyms such as bepecin or PL 14736 appear in older or company-linked publications. Purity claims and reported masses can also differ between sources because peptide preparations may include counterions, residual solvents, or bound water. This variability complicates direct comparison of results across studies and makes the exact identity and grade of a given sample worth verifying. Discussions of the compound should therefore specify the source, salt form, and stated purity where those are known.
BPC-157 is a synthetic peptide composed of fifteen amino acid residues, with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. Its name derives from body protection compound, a term used for a protein fraction identified in human gastric juice. Researchers in Zagreb first reported the pentadecapeptide in the early 1990s and described it as a stable fragment of that larger protein. The compound is also catalogued as PL 14736 and, in some commercial contexts, as bepecin. Its molecular formula is C62H98N16O22 and its monoisotopic mass is approximately 1419 daltons.
BPC-157 is a synthetic peptide of fifteen amino acids, written as GEPPPGKPADDAGLV, whose sequence matches part of a larger protein identified in human gastric juice. That parent protein was described in stomach-secretion research, and the fifteen-residue fragment was named body protection compound, which gives the peptide its common label. Material used in experiments is produced by solid-phase peptide synthesis rather than extracted from tissue. The reported molecular weight is about 1419 daltons, and the chain contains several proline residues, a feature that appears in discussions of its resistance to enzymatic breakdown.
Most published findings come from rodent models, where the peptide has been examined in wound-healing, gastrointestinal-lesion, tendon, and vascular-injury preparations. A smaller number of early human studies have been reported, chiefly in inflammatory bowel conditions, but the public record is short and has not led to marketing approval in the United States or the European Union. Reviewers therefore classify the compound as investigational, and whether animal results carry over to people remains an open question rather than a settled one.
Most published work on BPC-157 comes from animal experiments rather than controlled human trials. Rodent models have examined its effects on gastrointestinal lesions, tendon and ligament injury, and blood vessel formation. These studies are often small and originate from a limited number of research groups, which affects how broadly the findings can be generalized. No large randomized human trial has been reported in the peer-reviewed literature. Discussion of the compound therefore rests largely on preclinical data, and questions about its effects in people remain open rather than settled.
Several mechanisms have been proposed to explain the activity observed in animal models. The most frequently cited involve signaling through vascular endothelial growth factor receptor 2 and modulation of the nitric oxide system. Researchers have also described interactions with protective pathways in the gut lining. These proposed mechanisms appear in the literature as hypotheses supported by preclinical observations, not as confirmed pathways in humans. The precise way the peptide produces its reported effects, and whether those effects carry across species, remain areas of active and unresolved investigation.
BPC-157 is a synthetic pentadecapeptide, meaning it consists of fifteen amino acids joined in a single chain. Its sequence is Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, a fragment corresponding to part of a larger protein found in human gastric juice. The peptide was first described in the 1990s by researchers in Zagreb who were studying gastric protective factors. It is not a naturally circulating hormone; it is a laboratory-made fragment derived from a stomach protein. The name is an abbreviation of body protection compound, with the number referring to the fragment's position in the source protein.
BPC-157 is a synthetic fifteen-amino-acid peptide whose sequence is GEPPPGKPADDAGLV. Its name derives from the phrase body protection compound, a term applied to a protein fraction originally detected in human gastric juice. The short peptide is not that full protein; it corresponds to a stable fragment of the larger molecule. Researchers frequently describe it as a pentadecapeptide because it contains exactly fifteen residues. Its neutral molecular mass is approximately 1419 daltons.
The sequence places several glycine and proline residues near the middle, which may influence how the chain folds in solution. The peptide is linear rather than cyclic, and it carries no disulfide bridges. Commercial material is commonly supplied as the acetate salt, although the free base and other counterion forms also appear. Because the term BPC-157 refers to a specific sequence, samples with slight sequence variants are chemically different substances. Published work generally treats the fifteen-residue sequence as the defining structure.
Physical descriptions in supplier documents and papers usually list the compound as a white to off-white powder. It dissolves readily in water and in common aqueous buffers, and solutions are often prepared fresh before an experiment. Molecular mass near 1419 daltons helps verify identity during mass spectrometry. The powder is somewhat hygroscopic, so moisture exposure can alter the measured mass of a sample. Purity is typically reported as a percentage from chromatographic analysis.
2 I− + 2 Fe3+ → I2 + 2 Fe2+ (E0 = +0.23 V) Ferric iodide, a black solid, is not stable in ordinary conditions, but can be prepared through the reaction of iron pentacarbonyl with iodine and carbon monoxide in the presence of hexane and light at the temperature of −20 °C, with oxygen and water excluded. Complexes of ferric iodide with some soft bases are known to be stable compounds.
The 139th Boat Race took place on 27 March 1993. Held annually, the Boat Race is a side-by-side rowing race between crews from the Universities of Oxford and Cambridge along the River Thames. Cambridge, using "cleaver blades" for the first time in the history of the race, won by 3+1⁄2 lengths in a victory that was described in The Times as "crushingly conclusive". The winning time of 17 minutes exactly was the fourth-fastest time in the event. In winning the event, Cambridge prevented Oxford making it seventeen wins from the last eighteen races and levelling the overall score for the first time since the 1929 race. Oxford's crew featured two Olympic gold medallists and saw changes in their rowers and cox in the lead-up to the event. The race was umpired by the former Oxford Blue Mark Evans who controversially instigated changes to the start procedure of the race. In the reserve race, Cambridge's Goldie defeated Oxford's Isis, while Cambridge won the Women's Boat Race.
=== United States === The approach in the United States to stop money laundering is usually broken into two areas: preventive (regulatory) measures, and prosecutorial measures. In the United States, whistleblowers can report money laundering activities to the Financial Crimes Enforcement Network (FinCEN) or the Securities and Exchange Commission (SEC) if the case also implicates a security.
=== Toxicity === Ganciclovir is considered a potential human carcinogen, teratogen, and mutagen. It is also considered likely to cause inhibition of spermatogenesis. Thus, it is used judiciously and handled as a cytotoxic drug in the clinical setting.
Duchenne muscular dystrophy is extremely rare in females (about 1 in 50,000,000 female births). It can occur in females with an affected father and a carrier mother, in those who are missing an X chromosome, or in those who have an inactivated X chromosome (the most common of the rare reasons). The vast majority of clinical trials excluded female patients from enrollment, thus reducing the generalizability of the findings and limiting our understanding of potential sex-specific differences in disease manifestation and treatment response. The daughter of a carrier mother and an affected father will be affected or a carrier with equal probability, as she will always inherit the affected X-chromosome from her father and has a 50% chance of also inheriting the affected X-chromosome from her mother. Disruption of the blood–brain barrier has been seen to be a noted feature in the development of Duchenne muscular dystrophy.

==== Greece ==== The production of potassium alum from alunite is archaeologically attested on the island Lesbos. This site was abandoned in the 7th century but dates back at least to the 2nd century CE.
Other psychedelic phenethylamines, including the closely related 2C, DOx, and TMA drugs, are inactive as monoamine releasing agents and reuptake inhibitors. However, an exception is trimethoxyamphetamine (TMA), the amphetamine analogue of mescaline, which is a very low-potency serotonin releasing agent (EC50Tooltip half-maximal effective concentration = 16,000 nM). The possible monoamine-releasing effects of mescaline would likely be related to the compound's phenethylamine backbone Mescaline is a relatively low-potency psychedelic, with active doses in the hundreds of milligrams and micromolar affinities for the serotonin 5-HT2A receptor. For comparison, psilocybin is approximately 25-fold more potent (doses in the tens of milligrams) and lysergic acid diethylamide (LSD) is approximately 5,000-fold more potent (doses in the tens to hundreds of micrograms). There have been efforts to develop more potent analogues of mescaline. Difluoromescaline and trifluoromescaline are more potent than mescaline, as is its amphetamine homologue TMA. Escaline and proscaline are also both more potent than mescaline, showing the importance of the 4-position substituent with regard to receptor binding. Mescaline has been uniquely found to robustly produce aggression in rodents, an effect not shared by various other psychedelics. It is unclear why mescaline produces more nausea and vomiting than other psychedelics like LSD and psilocybin in humans.
Several different types of interferons are approved for use in humans. One was first approved for medical use in 1986. For example, in January 2001, the Food and Drug Administration (FDA) approved the use of PEGylated interferon-alpha in the USA; in this formulation, PEGylated interferon-alpha-2b (Pegintron), polyethylene glycol is linked to the interferon molecule to make the interferon last longer in the body. Approval for PEGylated interferon-alpha-2a (Pegasys) followed in October 2002. These PEGylated drugs are injected once weekly, rather than administering two or three times per week, as is necessary for conventional interferon-alpha. When used with the antiviral drug ribavirin, PEGylated interferon is effective in treatment of hepatitis C; at least 75% of people with hepatitis C genotypes 2 or 3 benefit from interferon treatment, although this is effective in less than 50% of people infected with genotype 1 (the more common form of hepatitis C virus in both the U.S. and Western Europe). Interferon-containing regimens may also include protease inhibitors such as boceprevir and telaprevir. There are also interferon-inducing drugs, notably tilorone that is shown to be effective against Ebola virus.

Nevertheless, benzodiazepines are still prescribed for long-term treatment of anxiety disorders, although specific antidepressants and psychological therapies are recommended as the first-line treatment options with the anticonvulsant drug pregabalin indicated as a second- or third-line treatment and suitable for long-term use. NICE stated that long-term use of benzodiazepines for panic disorder with or without agoraphobia is an unlicensed indication, does not have long-term efficacy, and is, therefore, not recommended by clinical guidelines. Psychological therapies such as cognitive behavioural therapy are recommended as a first-line therapy for panic disorder; benzodiazepine use has been found to interfere with therapeutic gains from these therapies.
== January 14, 1982 (Thursday) == An Ethiopian Air Force Antonov An-26 crashed near Addis Ababa, Ethiopia while transporting a group of Ethiopian, Libyan and Cuban soldiers to a fight in Eritrea. All 73 occupants on board were killed. It the state of Hidalgo in Mexico, near the town of Atotonilco de Tula, the bodies of 13 men were found by a drainage canal. The dead men would be found to have been from Colombia, who had been arrested, as well as a Mexican taxicab driver who had helped transport them to the scene of the deaths. Mexico City Police Chief Arturo Durazo Moreno, accused by a subordinate of having planned the killings, would end up fleeing Mexico after the inauguration of a new president. Robert Dale Henderson began a spree of mostly random murders that would kill 12 people across five U.S. states, in a little more than three weeks until his arrest on February 6, starting with a beautician in Cincinnati. One week later, on January 21, he murdered a family of three in Cherry Fork, Ohio, followed by the January 24 killing of a receptionist in Charleston, South Carolina, the January 25 homicides of a doctor and a clerk in Palatka, Florida and a mother and daughter later in the day in Valdosta, Georgia. He killed a nightclub owner in Port Allen, Louisiana on January 29, and three hitchhikers in Hernando County, Florida on February 4, before approaching a deputy sheriff at a shopping center in Punta Gorda, Florida, making a confession, and surrendering.

It is a synthetic peptide. Its design was inspired by a fragment of a protein found in human gastric juice, but the fifteen-amino-acid molecule itself is made in a laboratory and is not a normal component of food or of human tissue in appreciable amounts.
The number is an internal laboratory designation from the research group that first described the fragment. It does not encode a molecular weight, a receptor target, or a measured biological effect, and it carries no meaning outside the naming history of the compound.
It contains fifteen amino acid residues and has a calculated mass of roughly 1419.5 daltons. That places it in the short-peptide range, well below the size of small proteins, which affects how it is synthesized, purified, and analyzed.
It is a synthetic peptide of fifteen amino acids whose sequence matches a fragment of a protein found in human gastric juice. It is studied mainly in laboratory and animal research rather than as an approved medicine.
