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.
Within the research literature, the peptide is discussed through several provisional mechanisms, including cytoprotection, modulation of growth factor signaling, and interaction with the nitric oxide system. None of these mechanisms is fully characterized, and no single pathway is universally accepted. Review articles typically note the gap between consistent animal findings and sparse human evidence. The compound is classified as a research chemical rather than an approved pharmaceutical, which shapes how studies are designed, funded, and reported.
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 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.

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.
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.
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.
Early work on this family of molecules examined fractions of human gastric juice, where a larger protein was reported to protect gastrointestinal tissue in animal models. BPC 157 was designed as a shorter, more stable fragment of that protein and then studied on its own. The peptide itself is not a normal dietary component and is not present in the human body in meaningful quantities. Descriptions of its origin therefore refer to the research lineage of a laboratory molecule rather than to an endogenous or nutritional substance.
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.

== Taxonomy and phylogeny == Pholcus phalangioides was first described in 1775 by the Swiss entomologist Johann Kaspar Füssli. A member of the genus Pholcus in the family Pholcidae, P. phalangioides shares ancestry with roughly 1,340 similar cellar-spiders. All of these spiders are known for their characteristic long legs, which can range from 5 to 6 times the size of their bodies. This is not to be confused with organisms with similar physical appearances, such as the crane fly – an insect – and harvestmen of the arachnid order Opiliones.
==== Liver damage ==== Nicotinic acid in medicinal doses can cause modest elevations in serum transaminase and unconjugated bilirubin, both biomarkers of liver injury. The increases usually resolve even when drug intake is continued. However, less commonly, the sustained release form of the drug can lead to serious hepatotoxicity, with onset in days to weeks. Early symptoms of serious liver damage include nausea, vomiting and abdominal pain, followed by jaundice and pruritus. The mechanism is thought to be a direct toxicity of elevated serum niacin. Lowering dose or switching to the immediate release form can resolve symptoms. In rare instances the injury is severe, and progresses to liver failure.

A tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds. As for proteins, the function of peptides is determined by the constituent amino acids and their sequence. In terms of scientific investigations, the dominant tripeptide is glutathione (γ-L-Glutamyl-L-cysteinylglycine), which serves many roles in many forms of life.

== Research == As of June 2025, suvomipic is in phase 2 clinical trials for treatment of alopecia. Two clinical trials have been completed, including a phase 1 trial and a phase 2a trial. There were initial concerns that suvomipic might actually kill all hair follicles rather than promote hair growth, but its developers were pleased to find that this was not the case. The effectiveness data for a phase 2a trial was released in June 2025. In this preliminary trial, 31% of men with "advanced baldness" or "a higher degree of hair loss" experienced an increase in hair density of 20% or more at the 8-week follow-up point subsequent to 4 weeks of suvomipic treatment, whereas none of the men in the placebo group showed improvement. Existing hair-loss drugs like minoxidil and finasteride are said to require months to produce any visible difference. The new hair growth was described as not being vellus hair, peach fuzz, or baby hair, but as being proper and thick terminal hair, and to have grown in previously bald areas. However, Pelage Pharmaceuticals declined to share before-and-after photos, citing regulations preventing them from doing so. Moreover, the trial was a short-term study that was primarily designed to assess safety and not efficacy. A three-month open-label extension of the phase 2a trial was subsequently completed and these data will be shared in 2026.
The teeth differed slightly (they were heterodont) based on position: those near the tips of the upper jaws (on the premaxillae) were slender and lacked serrations, while those behind them (on the maxillae) were serrated and laterally compressed. The teeth of the lower jaws were similarly differentiated. A pigmented area in the abdomen of the holotype has been suggested as possible traces of organs, and was interpreted as the liver by John Ruben and colleagues, which they described as part of a crocodilian-like "hepatic piston" respiratory system. A later study, while agreeing that the pigmented area represented something originally inside the body, found no defined structure and noted that any organs would have been distorted by the processes that flattened the skeleton into an essentially two-dimensional form. Dark pigment is also present in the eye region of the holotype and another specimen.
Musculoskeletal The first joint symptoms that patients with scleroderma have are typically nonspecific joint pains, which can lead to arthritis, or cause discomfort in tendons or muscles. Joint mobility, especially of the small joints of the hand, may be restricted by calcinosis or skin thickening. Patients may develop muscle weakness, or myopathy, either from the disease or its treatments.

The sequence corresponds to a fragment of a protein found in human gastric juice, so related sequences are natural. The isolated fifteen-amino-acid peptide supplied for research is produced synthetically. Whether the free fragment circulates naturally in humans has not been settled.
In most jurisdictions it is not an approved medicine and is handled as a research material. Import and sale rules differ by country, and some regulators have placed it in categories that restrict human use. Status can change, so current local rules apply.
Rodent models dominate, particularly rats with induced gastric lesions, tendon injury, or vascular disruption. These designs allow controlled comparison but differ anatomically and metabolically from humans. Results from such models are commonly cited as preliminary.
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.
