The short version of gastric juice protein fits in a sentence. The long version — which is the one that helps — is below.
This page was last updated on 2026-03-07 and is reviewed periodically as new material appears.
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.
Outside laboratory supply channels, the peptide is sold as a research chemical, a category that carries no requirement to demonstrate purity, identity, or freedom from contamination. Because it is not an approved medicine, products labeled BPC-157 sit in a regulatory gap in many countries, and actual content may differ from the label. Sports organizations list it among prohibited substances, so its presence in an athlete's sample can produce a doping finding regardless of how the material was obtained.
Proposed mechanisms include interaction with the nitric oxide system, modulation of growth factor signaling, and effects on blood vessel formation. None of these has been established as the primary mode of action, and some proposed pathways rest on indirect measurements. Whether the reported effects depend on a specific receptor has not been determined. Stability in gastric acid, unusual for a peptide of this size, is also reported in animal work, but the reason for it is not firmly established.
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.

Once dissolved, the material is considerably less stable than the dry solid. Aqueous solutions are usually kept cold and used within a short window, and neutral or mildly acidic buffers are preferred over strongly alkaline conditions. Freeze-thaw cycles promote aggregation and loss of material to container surfaces, so dividing a batch into single-use aliquots is standard. Adsorption to plastic and glass can lower the measured concentration, meaning solution strength may need rechecking before an experiment.
Identity and purity are established with complementary methods rather than one test. Reverse-phase high-performance liquid chromatography separates the main peak from deletion sequences and oxidized variants, and its area percentage is the usual purity figure. Mass spectrometry confirms the expected molecular mass and can flag truncations or modifications that chromatography alone might miss. Amino acid analysis and peptide mapping add sequence-level confirmation, while residual counter-ion and water content are measured separately.
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.
Some properties, such as the peptide's sequence and molecular mass, are firmly established. Other claims, particularly about mechanism and clinical benefit, remain open questions. Proposed mechanisms include effects on nitric oxide signaling and on cell migration, but these are hypotheses supported by limited evidence. Reviewers often note that the field lacks large controlled human trials. Positive animal findings are best treated as signals for further study rather than as settled conclusions.
Most published studies examine BPC-157 in animal models rather than in humans. Common subjects include rats and mice, and researchers often use models of tissue injury, surgery, or induced inflammation. Reported endpoints include healing rates, blood vessel formation, and markers of tissue repair. These designs provide controlled comparisons, but findings in animals do not automatically transfer to people. Human clinical data remain limited and are frequently described as preliminary.
== Other == Lower levels of adiponectin are associated with ADHD in adults. Adiponectin levels were found to be increased in rheumatoid arthritis patients responding to DMARDs or TNF inhibitor therapy. A low adiponectin to leptin ratio has been found in patients with COVID-19 pneumonia compared to healthy controls. Exercise induced release of adiponectin increased hippocampal growth and led to antidepressive symptoms in mice. Several studies have found a positive correlation in caffeine consumption and increased adiponectin levels, although the mechanism for this is unknown and requires more research.
== Chemistry == Unlike the hormones with which it competes, flutamide is not a steroid; rather, it is a substituted anilide. Hence, it is described as nonsteroidal in order to distinguish it from older steroidal antiandrogens such as cyproterone acetate and megestrol acetate.
== Research == A 2014 Cochrane review found insufficient evidence to make a conclusion about its use for the prevention of heart disease. A 2016 Cochrane review concluded that CoQ10 had no effect on blood pressure. A 2021 Cochrane review found "no convincing evidence to support or refute" the use of CoQ10 for the treatment of heart failure. A 2017 meta-analysis of people with heart failure taking 30–100 mg/d of CoQ10 found a 31% lower mortality and increased exercise capacity, with no significant difference in the endpoints of left heart ejection fraction. A 2021 meta-analysis found that CoQ10 was associated with a 31% lower all-cause mortality in HF patients. In a 2023 meta-analysis of older people, ubiquinone had evidence of a cardiovascular effect, but ubiquinol (the reduced form) did not. Although CoQ10 has been studied as a potential remedy to treat purported muscle-related side effects of statin medications, the results were mixed. Although a 2018 meta-analysis concluded that there was preliminary evidence for oral CoQ10 reducing statin-associated muscle symptoms, including muscle pain, muscle weakness, muscle cramps, and muscle tiredness, 2015 and 2024 meta-analysis found that CoQ10 had no effect on statin myopathy.
He was succeeded by Robin Dutt, who himself left the club for Bayer Leverkusen in 2011. On 10 May 2009, Freiburg secured promotion into the Bundesliga once again, beating TuS Koblenz in an away game 5–2.
== Etymology == The name "buckwheat" comes from its tetrahedral seeds, which resemble the much larger seeds of the beech nut from the beech tree, and the fact that it is used like wheat. The word may be a translation of Middle Dutch boecweite: boec "beech" (Modern Dutch beuk; see PIE *bhago-) and weite "wheat" (Mod. Dut. tarwe, antiquated weit), or may be a native formation on the same model as the Dutch word.

The therapeutic uses of puffer fish (tetraodon) eggs were mentioned in the first Chinese pharmacopoeia Pen-T'so Ching (The Book of Herbs, allegedly 2838–2698 BC by Shennong; but a later date is more likely), where they were classified as having "medium" toxicity, but could have a tonic effect when used at the correct dose. The principal use was "to arrest convulsive diseases". In the Pen-T'so Kang Mu (Index Herbacea or The Great Herbal by Li Shih-Chen, 1596) some types of the fish Ho-Tun (the current Chinese name for tetraodon) were also recognized as both toxic yet, at the right dose, useful as part of a tonic. Increased toxicity in Ho-Tun was noted in fish caught at sea (rather than river) after the month of March. It was recognized that the most poisonous parts were the liver and eggs, but that toxicity could be reduced by soaking the eggs. (Tetrodotoxin is slightly water-soluble, and soluble at 1 mg/ml in slightly acidic solutions.) The German physician Engelbert Kaempfer, in his "A History of Japan" (translated and published in English in 1727), described how well known the toxic effects of the fish were, to the extent that it would be used for suicide and that the Emperor specifically decreed that soldiers were not permitted to eat it. There is also evidence from other sources that knowledge of such toxicity was widespread throughout southeast Asia and India. The first recorded cases of TTX poisoning affecting Westerners are from the logs of Captain James Cook from 7 September 1774. The crew received a fish from the New Caledonia natives.
=== 6 August === The SAF claimed to have shot down an Emirati aircraft carrying Colombian mercenaries as it landed at Nyala Airport, killing 40 people. The United Arab Emirates Ministry of Foreign Affairs denied the accusation, calling it unfounded and lacking evidence.
A clinical evaluation of Prontosan wound cleanser was undertaken with ten community care patients where saline had been used for at least one month previously on wounds that had a mean duration of 2.6 years. The findings include; an overall reduction in wound size, a reduction in malodour, reduction or elimination of wound pain. These results correlate well with the patients' reports of improvement in quality of life and a reduction in the number of nursing visits. In addition, the wound cleansing effects of Prontosan with achieving a visible wound bed was reported by the author and linked to the removal of wound biofilm. Although this association is speculative it does appear to correspond with the other reported improvements found in these wounds.
Improved serological surveillance would allow governments, aid agencies, and policy writers to direct public health resources to where they are needed most. A better understanding of infection dynamics with respect to the changing patterns of global weather should inform policy measures including where to concentrate vaccination efforts and insect control measures. In April 2020, Justin Trudeau formed the COVID-19 Immunity Task Force, whose mandate is to carry out a serological survey in a scheme hatched in the midst of the COVID-19 pandemic.

It is not approved for human use in the United States or the European Union. Clinical material has been studied in a small number of early trials, mainly for inflammatory bowel conditions, and the compound remains investigational. Regulators treat marketed products as unapproved rather than as authorized drugs.
The peptide was named after a protein fraction found in human gastric juice, and the shorter form was called body protection compound. That phrase was shortened to the abbreviation BPC. The number 157 refers to a laboratory designation used in the original isolation work.
Its sequence corresponds to a segment of a protein present in gastric secretions, but the material supplied for research is made synthetically. No commercial product is purified from human or animal tissue. The synthetic route is used because it gives a defined chain length and a reproducible sequence.
It is not authorized as a medicine in the United States or the European Union. Regulatory treatment varies by jurisdiction, and in several places it is handled as a research chemical. Therapeutic claims are not supported by large human trials.
