The short version of BPC-157 fits in a sentence. The long version — which is the one that helps — is below.
This page was last updated on 2026-03-06 and is reviewed periodically as new material appears.
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 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.

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 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.
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.
Evidence in humans is limited. Small clinical studies have examined the peptide in contexts such as ulcerative colitis and wound healing, but participant numbers are small and independent replication is scarce. It is not approved as a medicine by major regulatory agencies and is distributed mainly as a research material or compounded preparation. Long-term human safety data are not established, and questions about absorption through non-injected routes remain open rather than resolved. Claims about its effects are best read against these gaps.
== Awards and recognitions == The hospital's wound healing center has been recognized by Healogics, with the Center of Excellence Award four consecutive years and the Center of Distinction Award five consecutive years. AdventHealth Lake Wales received a grade A from The Leapfrog Group in 2025 and May 2026.

==== Mechanism ==== Number of chiral environments are created within the polymer. Cavities are formed between adjacent glucose units, and spaces/channels between polysaccharide chains. These chiral cavities or channels give the chiral discrimination capability to polysaccharide CSPs. The mechanism of Chiral discrimination is not well understood but believed to involve hydrogen bonding and dipole-dipole interaction between the analyte molecule and the ester or carbamate linkage of the CSP.

MODY2: Homozygous glucokinase deficiency causes severe congenital insulin deficiency resulting in persistent neonatal diabetes mellitus. About 6 cases have been reported worldwide. All have required insulin treatment from shortly after birth. The condition does not seem to improve with age. MODY4: Homozygous IPF1 results in failure of the pancreas to form. Congenital absence of the pancreas, termed pancreatic agenesis, involves deficiency of both endocrine and exocrine functions of the pancreas. Homozygous mutations in the other forms have not yet been described. Those mutations for which a homozygous form has not been described may be extremely rare, may result in clinical problems not yet recognized as connected to the monogenic disorder, or may be lethal for a fetus and not result in a viable child.
== Inhibitors == There are two types of inhibitor of PPO, those competitive to oxygen in the copper site of the enzyme and those competitive to phenolics. Tentoxin has also been used in recent research to eliminate the PPO activity from seedlings of higher plants. Tropolone is a grape polyphenol oxidase inhibitor. Another inhibitor of this enzyme is potassium metabisulfite. Banana root PPO activity is strongly inhibited by dithiothreitol and sodium metabisulfite, as is banana fruit PPO by similar sulfur-containing compounds including sodium dithionite and cysteine, in addition to ascorbic acid (vitamin C).
== Causes == The etiology, or causes, of BPD involves several causes, with no consensus on a single one. BPD may share a connection with post-traumatic stress disorder (PTSD), with both having a traumatic substrate. While childhood trauma is a recognized contributing factor, the roles of congenital brain abnormalities, genetics, neurobiology, and non-traumatic environmental factors remain subjects of ongoing investigation.
Sfinxul is a natural rock formation in the Bucegi Natural Park which is in the Bucegi Mountains of Romania. This rock formation is named for its resemblance to the Sphinx of Giza, and is located at an altitude of 2,216 metres (7,270 feet) within the Babele complex of rock formations.

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.
