The short version of gastric protein fits in a sentence. The long version — which is the one that helps — is below.
Reviewed 2026-03-06. Anything still debated is marked as such rather than presented as settled.
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.
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.
BPC-157 is a synthetic pentadecapeptide whose sequence is commonly given as Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. It is described in the literature as a fragment of a larger protein found in human gastric juice, referred to as body protection compound. The peptide was first characterized in the early 1990s by a research group in Zagreb, Croatia. Its molecular formula is C62H98N16O22 and its monoisotopic mass is approximately 1419 daltons.
Supplied material is typically a lyophilized white to off-white powder. The peptide is freely soluble in water and in common aqueous buffers, which allows it to be handled as a stock solution. Because the sequence contains no cysteine, disulfide cross-linking is not a route of degradation. The absence of aromatic residues means ultraviolet absorbance at 280 nm is minimal, so quantification usually relies on peptide bond absorbance near 214 nm or on amino acid analysis.
Common synonyms in catalogs include pentadecapeptide BPC 157, BPC157, and the full sequence name. A CAS registry number in the 137525-51-0 range is frequently listed, though the assignment should be verified against the supplier certificate of analysis. The name itself is not a pharmacopoeial designation, and there is no standardized international nonproprietary name. Distinguishing genuine material from related fragments generally requires mass spectrometry, since several truncated sequences share similar chromatographic behavior.

BPC-157 is a synthetic peptide built from fifteen amino acid residues. Its sequence comes from a larger protein fragment that researchers isolated from human gastric juice and described as a body protection compound. The fragment contains glycine, glutamic acid, five prolines, lysine, alanine, two aspartic acids, leucine, and valine. The number 157 in the name refers to the position of the stretch within the parent protein. Material used in laboratories is manufactured rather than extracted from stomach fluid.
The molecule carries 15 residues, a molar mass near 1419.5 g/mol, and the formula C62H98N16O22. Its structure features a proline-rich central region, a pair of adjacent aspartic acid residues, and no cysteine. The absence of cysteine means no disulfide bonds can form, which simplifies refolding and reconstitution. Suppliers usually ship the material as a freeze-dried powder that appears white to off-white. It dissolves readily in water and in saline solutions.
Published storage guidance follows general peptide practice rather than product-specific studies. The dry powder is typically kept at minus 20 degrees Celsius, away from light and moisture. Once reconstituted, solutions are generally refrigerated and used over days to weeks, because the aqueous environment slowly promotes hydrolysis and oxidation. Long-term data on degradation rates or breakdown products are sparse. Stated shelf lives from different producers vary widely, reflecting the absence of a shared reference standard.
BPC-157 is a synthetic peptide of fifteen amino acids, written in single-letter code as GEPPPGKPADDAGLV. The sequence corresponds to a partial fragment of a protein isolated from human gastric juice, described in early reports as body protection compound. The number 157 refers to a fragment designation in that work rather than to molecular mass. Initial descriptions appeared in the early 1990s, when the fragment was reported to protect gastrointestinal tissue in animal models. Commercial material is produced by solid-phase peptide synthesis rather than extracted from biological sources.
Laboratory research on this peptide has examined a wide and heterogeneous set of endpoints, including gastric ulcer models, tendon and ligament injury, wound closure, and intestinal inflammation. Most published findings come from rodent studies, and reported effect sizes are often large relative to controls. Because the compound has been tested across many unrelated injury models, the literature is frequently described as unusually broad for a single peptide. A substantial share of this work originates from a small number of research groups, which matters when assessing how widely results have been reproduced.
BPC-157 is a synthetic pentadecapeptide with the sequence GEPPPGKPADDAGLV, corresponding to a partial fragment of a larger protein detected in human gastric juice. The name derives from the parent protein designation BPC, an abbreviation of body protection compound, with 157 acting as a fraction or batch identifier used by the original investigators. Its molecular weight is approximately 1419 daltons, and the chain contains no unusual residues or disulfide bridges. In the literature it is described as a short, water-soluble fragment rather than a complete natural protein.
Most early work on this peptide originated in the 1990s from a research group in Zagreb, Croatia, relying on animal models and cell cultures. Reported observations included effects on gastrointestinal lesion healing, tendon fibroblast migration, and blood vessel formation under controlled laboratory conditions. These findings come predominantly from rodent studies and in vitro assays rather than from human trials. Controlled human data remain limited, and the degree to which animal results translate to human physiology is an open question rather than a settled fact.
Part of the WADA submission to the appeal, which the CAS accepted in its verdict, was that Thymosin Beta-4 was the only form of Thymosin which would have had the soft tissue recovery effect that Dank had attributed to it – text messages from Dank had specifically described Thymosin as the cornerstone of the soft tissue recovery program. Two urine samples taken from Essendon players during 2012 were also found to contain elevated Thymosin Beta-4; the levels were not high enough to fail the drug test, but they added to the cable of evidence against the players. Significantly, the CAS also determined that the players were "significantly at fault", disqualifying them from any penalty reduction. This was considered a surprise, as press throughout the entire saga had opined that by having followed the direction of club officials, the players would be found to have had no significant fault or negligence, qualifying them for a 50% penalty reduction. Key to this finding was the revelation that none of the eighteen different players who had been drug tested on a total of thirty occasions during the program had declared the supplements injections on their doping control forms, and that some had withheld information from the club doctor on Dank's instruction – revelations which damaged the credibility of other evidence put forward by the players.

Some slow cookers have lids that seal to prevent their contents from spilling during transport. The ability to food to be slow-cooked ahead of time is regarded by some cooks as convenient. Drawing little energy, it is used in some households so it can draw entirely on 1–2 kW solar panels during the day. Slow cookers are less dangerous than ovens or stove tops due to their lower operating temperatures and closed lids. However, they still contain a large amount of foods and liquids at temperatures close to boiling, and they can cause serious scalds if spilled.
== Taxonomy == Tricholoma equestre was known to Carl Linnaeus, who officially described it in Volume Two of his Species Plantarum in 1753, giving it the name Agaricus equestris, predating a description of Agaricus flavovirens by Persoon in 1793. Thus this specific name meaning "of or pertaining to horses" in Latin takes precedence over Tricholoma flavovirens, the other scientific name by which this mushroom has been known. It was placed in the genus Tricholoma by German Paul Kummer in his 1871 work Der Führer in die Pilzkunde. The generic name derives from the Greek trichos/τριχος 'hair' and loma/λωμα 'hem', 'fringe' or 'border'. Common names include the man-on-horseback, yellow knight, and saddle-shaped tricholoma.

The letters BPC stand for body protection compound. The number 157 refers to a specific fragment designation from early work on gastric proteins. The full name is a label for a synthetic fifteen-amino-acid peptide rather than a naturally isolated drug.
No. The gastric protein is larger, while BPC-157 is a short fragment sequence. The peptide is produced synthetically for research use. The relationship is one of sequence origin, not chemical identity.
It is most often supplied as a lyophilized powder, frequently as the acetate salt. The powder is reconstituted with water or a buffer before use. Free-base and other salt forms also exist but are less common in catalogs.
It is a synthetic peptide built from fifteen amino acids, with a mass of roughly 1419 daltons. The sequence is reported to match a fragment of a protein present in human gastric juice. It is not a naturally circulating hormone.
