Summary

The evidence base for BPC-157 is overwhelmingly rodent studies. A 2025 systematic review of the musculoskeletal literature identified 36 includable studies, of which 35 were preclinical and one clinical 1. Nothing on this page should be read as extending those findings to humans: the human record consists of two meeting abstracts, one registered phase 1 study without posted results, three small uncontrolled reports from single clinics, and three further registered studies that have not reported 23456.

BPC-157 is a synthetic 15-residue peptide, GEPPPGKPADDAGLV, reported to be a partial sequence of a body protection compound isolated from human gastric juice and first described by Sikirić and colleagues at the University of Zagreb in 1993 72. No molecular target has been identified, and FDA states that the mechanisms of action remain poorly understood 2. No product containing the free base or the acetate is authorised in any country, and in a briefing document dated 11 May 2026 FDA proposed not adding either substance to the 503A bulk drug substances list 2. BPC-157 has been named by example in section S0 of the WADA Prohibited List since the 2022 List and is prohibited at all times 89.

Identity and structure

Sequence and residues

The molecule is a linear pentadecapeptide with the one-letter sequence GEPPPGKPADDAGLV, written in three-letter form as H-Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val-OH 10112. It carries a free N-terminal glycine amine and a free C-terminal valine carboxylate; no amidation, acylation, cyclisation or non-natural residue is recorded in the substance registry protein record or in FDA's structural description 102. A review of the biopharmaceutical literature attributes the peptide's reported resistance to gastric proteolysis to the conformational rigidity of the N-terminal polyproline segment, identifies the Asp10–Asp11 junction as the principal acid-hydrolysis liability, and notes that the sequence contains no methionine, cysteine, tryptophan, asparagine or glutamine and therefore no residue prone to oxidation or deamidation 12.

Acetate, and the absence of an arginate record

The dossier resolves salt identity as follows. The free peptide carries UNII 8ED8NXK95P, CAS 137525-51-0, PubChem CID 9941957 and the formula C62H98N16O22, with a molecular weight of 1419.5 g/mol in PubChem and in FDA's table and 1419.54 on supplier certificates 10132. The acetate is separately registered with UNII PAR2FC72XP and CAS 216441-37-1; the substance registry gives the monoacetate a molecular weight of 1479.59 g/mol, while FDA writes the formula with an unspecified number of acetate equivalents and records the weight as not available for that reason 142. PubChem lists a second registry number, 1628202-19-6, among the acetate synonyms alongside 216441-37-1, and the two are not reconciled by the sources retrieved 15.

No search of PubChem or of the substance registry conducted for the dossier returned any record for a BPC-157 arginate or arginine salt, and FDA's evaluation covers only the free base and the acetate 13102. A material described as an arginate therefore has no identifiers to check a certificate against. FDA treats naming inconsistency across salts and derivatives sold under one common name as a risk in itself, on the grounds that it creates the possibility of dispensing a substance other than the one ordered 2. Other identifiers recorded on the free-peptide record include PL-10, PL-14736 and PLD-116 1013.

Mechanism and pharmacology

No receptor or molecular target has been identified. FDA states that the molecular targets for BPC-157-related substances have not been identified and that the mechanisms of action remain poorly understood, which makes the biological plausibility of the reported effects difficult to assess; a 2026 review reaches the same conclusion, reporting that no high-affinity binding site has been identified 212.

The proposed mechanisms in the primary literature are associations observed in cell and animal models rather than demonstrated binding. They include up-regulation and internalisation of VEGFR2 with activation of the VEGFR2–Akt–eNOS pathway in endothelial cells and in rat hind-limb ischaemia 16, increased growth hormone receptor expression in cultured rat Achilles tendon fibroblasts 17, and increased tendon fibroblast outgrowth, survival under hydrogen peroxide stress and migration with dose-dependent FAK and paxillin phosphorylation 18. A scoping review summarises these as VEGFR2, Akt–eNOS, ERK1/2 and anti-inflammatory signalling 19.

The endogenous origin is reported rather than demonstrated in every source retrieved. FDA uses the qualified wording that BPC-157 is reported to be a pentadecapeptide fragment of a body protection compound found in gastric juice, and notes that the 1993 authors described it as a possible endogenous free radical scavenger and organoprotection mediator 27. A 2026 review states that the parent protein remains uncharacterised 12. Whether an endogenous BPC-157 sequence exists in humans is therefore unresolved on the present record.

Animal disposition has been characterised. After a single intravenous dose the elimination half-life of the parent peptide was 15.2 minutes in Sprague Dawley rats and 5.27 minutes in Beagle dogs, with linear kinetics and intramuscular bioavailability of approximately 14 to 19 per cent in rats and 45 to 51 per cent in dogs; excretion was mainly urinary and biliary, and radiolabelled peptide was rapidly degraded to small fragments and free amino acids 202. Human pharmacokinetics are essentially absent: in the two rectal-enema studies in which plasma was sampled BPC-157 was not detected, and FDA found no human pharmacokinetic data after oral, subcutaneous, nasal or transdermal administration 2.

A disputed literature

The interpretation of this body of work is actively contested in the peer-reviewed literature. An independent review by Jóźwiak and colleagues in 2025 raised the possibility of adverse consequences of sustained angiogenic and nitric-oxide effects 21; the Zagreb group published a comment defending the cytoprotection model and the compound's safety 22; and the review authors published a reply 23. A separate commentary in Inflammopharmacology discusses a large 2024 review by the same group 24. The same independent review states that BPC-157 is not currently listed as prohibited by WADA; the Prohibited List in force names it in section S0, so that statement is contradicted by the primary source 219.

Clinical and preclinical evidence

What human data exist

The human record is set out in full below. Two of the entries are meeting abstracts that FDA read rather than peer-reviewed publications, one is a registered phase 1 study whose registry status has been "unknown" since 2015 and for which FDA located no publication, and three are uncontrolled reports from single clinics 23. Three further registered studies, two randomised and one single-arm, have posted no results 252627. One systematic review found no clinical safety data at all, and a 2026 narrative review of peptides in sports medicine records that rigorous human safety data for the unapproved peptides it surveys, BPC-157 among them, are scarce 11928.

What the human record does not support

No conclusion about effect in humans follows from the table above. Two entries are meeting abstracts, one registered trial has never reported, and the three clinic reports are uncontrolled, unblinded and, in one case, of two people. FDA judges the ulcerative colitis data inadequate to support efficacy or safety 21.

Analytical characterisation

There is no United States Pharmacopeia or National Formulary monograph for the free base or the acetate, and none in the European Pharmacopoeia (11th edition, 11.8), the Japanese Pharmacopoeia (18th edition) or the International Pharmacopoeia (12th edition) 2. Certificates of analysis reviewed by FDA typically report purity alone: one nomination certificate for the acetate reported 97.8 per cent against a limit of at least 95 per cent, with individual and total related-substance limits of 3.0 and 5.0 per cent and results of 1.1 and 2.2 per cent, the impurities neither identified nor specified, and a second reported purity alone at 98.34 per cent 2. FDA found no impurity-profile, aggregate, bioburden, bacterial endotoxin or residual-solvent data in the nominations or the public literature and concluded that immunogenicity from impurities and peptide aggregates cannot be ruled out; the expected impurity classes are those of solid-phase peptide synthesis, including truncation and incomplete-coupling sequences, isomeric impurities, free amino acids, residual solvents, coupling reagents and aggregates 2. FDA describes the originally published synthesis as stepwise Fmoc solid-phase condensation on a benzhydrylamine resin, with purification by high-performance liquid chromatography to greater than 95 per cent purity 2.

The most detailed published characterisation comes from anti-doping analysis. A validated weak cation exchange solid-phase extraction method for urine reached a detection limit of 0.1 ng/mL with precision better than 20 per cent, and used a stable metabolite alongside the parent peptide to improve specificity 11. A stable-isotope-labelled, non-targeted ultra-high-performance liquid chromatography and high-resolution mass spectrometry workflow identified nine in vitro metabolites and validated detection of BPC-157 and five main metabolites in human urine at 0.01 to 0.11 ng/mL 29. A 2026 multi-analyte workflow includes BPC-157 among 54 prohibited compounds in dried blood spots, serum and plasma, with detection limits of 0.05 to 1.25 ng/mL 30.

Stability and handling

Laboratory handling data only, as reported in the literature. BPC-157 was reported to resist hydrolysis in human gastric juice in vitro, which FDA cites as the reason its short half-life in vivo is attributed to blood and tissue peptidases; the same property is asserted in the Zagreb group's review literature 231.

  • Lyophilised material is reported stable at room temperature for three weeks, with desiccated storage below −18 °C recommended; solution is reported stable for two to three weeks at 4 °C and three to four months at −20 °C. FDA concludes that the free base is expected to be stable below −18 °C and the acetate below −20 °C, and attributes these particular figures in its own footnotes to commercial supplier pages rather than to peer-reviewed work 2.
  • Solubility is reported as 5 mg/mL in water for both forms, the material described as a white to off-white lyophilised powder with a melting point above 232 °C; those figures are also footnoted to supplier pages, and no formal solubility profiling across physiological pH values has been published 212.
  • In an anti-doping stability study, BPC-157 in serum showed complete degradation after one week at 4 °C and at 22 °C, while all compounds studied were stable for at least two months at −20 °C in the blood matrices examined and remained detectable in dried matrices 30.
  • FDA notes that peptides of this kind are sensitive to pH, temperature, concentration, in-process impurities and excipients, and that aggregation can form during storage or stress and may require size exclusion chromatography or field flow fractionation to detect 2.

The July 2026 advisory committee proposal

Two nominations for the 503A bulk drug substances list, from Wells Pharmacy Network and from LDT Health Solutions with the International Peptide Society, were withdrawn, and FDA elected to evaluate both the free base and the acetate at its own discretion for the treatment of ulcerative colitis 2. In a briefing document dated 11 May 2026 for the Pharmacy Compounding Advisory Committee meeting of 23 and 24 July 2026, FDA proposed not adding either substance to the 503A list, on the grounds that both are not well characterised, that naming inconsistencies across salts and derivatives sold under one common name create a risk of dispensing a different substance from the one ordered, that immunogenicity risk from aggregates and peptide-related impurities cannot be excluded, that the evidence of effectiveness in ulcerative colitis is insufficient, and that approved therapies exist 235. FDA's category 2 page, current as of 22 April 2026, carries BPC-157 in the list of bulk drug substances nominated but withdrawn 34. Three adverse event reports retrieved by FDA through 4 December 2025 describe injection-site redness and swelling, shortness of breath, and reproducible diffuse hyperpigmentation with gingival darkening on rechallenge; each is confounded by concomitant peptides or missing detail 2.

Anti-doping

BPC-157 is named as an example in section S0, Non-Approved Substances, of the Prohibited List in force. Substances in that class are Specified Substances; any pharmacological substance not addressed by a later section and with no current approval by any governmental regulatory health authority for human therapeutic use is prohibited at all times 9. WADA stated on 30 September 2021 that BPC-157 was the first substance ever included by name as an example in section S0, on the 2022 List, which came into force on 1 January 2022 8.

Open questions

  1. The parent body protection compound protein has not been characterised in any source retrieved, and whether an endogenous BPC-157 sequence exists in humans is unresolved 212.
  2. No molecular target has been identified; the VEGFR2, growth hormone receptor and nitric oxide mechanisms are reported as associations in animal and cell models 21617.
  3. No record of an arginate or arginine salt was found in PubChem or the substance registry, and PubChem lists two registry numbers among the acetate synonyms without reconciling them 15142.
  4. No dose-response relationship has been established: across the rodent studies reviewed by FDA, microgram and nanogram per kilogram doses produced effects of comparable magnitude 2.
  5. The Zagreb literature describes BPC-157 as having entered clinical phase II for inflammatory bowel disease, whereas FDA identified only a single meeting-abstract trial and judged the data inadequate, and a 2026 review states that no phase II trial has been completed 31212.
  6. No results have been posted for NCT02637284, whose registry status has been unknown since 2015, for NCT07752381, completed in November 2025, or for any other registered study 327.
  7. The coagulation and liver-associated signals in the 28-day animal studies have not been reproduced in longer studies, and no carcinogenicity study exists 236.
  8. The European finding rests on the Union Register, because the EMA website could not be retrieved when the dossier was compiled 33.

Questions this page answers

What does the evidence base for BPC-157 actually consist of?
Almost entirely animal work. A 2025 systematic review of the musculoskeletal literature identified 36 includable studies, of which 35 were preclinical and one clinical. The human record comprises two meeting abstracts, a registered phase 1 study with no posted results, three small uncontrolled clinic reports and three registered trials that have not reported.
Is BPC-157 an endogenous peptide?
Not as demonstrated by any source retrieved for the dossier. FDA uses the qualified wording that BPC-157 is reported to be a fragment of a body protection compound found in gastric juice, and a 2026 review states that the parent protein remains uncharacterised. Whether an endogenous BPC-157 sequence exists in humans is unresolved.
Does BPC-157 exist as an arginate salt?
No record of a BPC-157 arginate or arginine salt was returned by any PubChem or GSRS search conducted for the dossier, and the FDA evaluation covers only the free base and the acetate. Identifiers for the free base and the acetate are separately registered; a material described as an arginate cannot be verified against a substance record.
What is the current FDA position on BPC-157?
In a briefing document dated 11 May 2026 for the Pharmacy Compounding Advisory Committee meeting of 23 and 24 July 2026, FDA proposed not adding either BPC-157 (free base) or BPC-157 acetate to the 503A bulk drug substances list, citing poor characterisation, naming inconsistencies, immunogenicity risk and insufficient evidence of effectiveness in ulcerative colitis.
Is BPC-157 prohibited in sport?
Yes. It is named as an example in section S0, Non-Approved Substances, of the WADA Prohibited List in force, and substances in that class are prohibited at all times. WADA stated in September 2021 that BPC-157 was the first substance ever included by name as an example in S0, on the 2022 List.
