Overview

BPC-157 is a synthetic 15-amino-acid peptide derived from a protein found in human stomach juice. It is one of the most widely discussed research peptides, particularly among people interested in joint, tendon, and gut recovery. It has no approval from any major regulatory agency and has not completed any human Phase III clinical trial. Most of what is known comes from animal studies — predominantly rats — conducted largely by a single research group in Croatia.

Summary

BPC-157 has no marketing authorisation from any major regulatory agency. No human Phase III clinical trials have been completed. The preclinical evidence base consists of over 100 animal studies, predominantly conducted at the University of Zagreb. A small pilot study in ulcerative colitis (4 patients) has been reported but was uncontrolled.

No established human dosing, safety profile, or efficacy data from rigorous clinical trials exist. Products available through unregulated channels are not subject to pharmaceutical manufacturing standards, and their composition, purity, and sterility cannot be assured. The gap between the extensive animal literature and the near-complete absence of human clinical data is the defining feature of this compound's evidence base.

Mechanism of Action

Research in animal models suggests BPC-157 may interact with multiple biological pathways including growth factor signalling, nitric oxide systems, and collagen organisation. These proposed mechanisms are derived from preclinical studies, predominantly from a single research group. No mechanisms have been validated in controlled human trials, and the compound's pharmacological activity in humans is not established.

Research Summary

Research in animal models suggests positive effects on tendon healing, gut repair, and nerve regeneration, with results that have been consistently positive across over 100 animal studies. However, the vast majority of this research comes from one group at the University of Zagreb. A small pilot study in ulcerative colitis (4 patients) has been reported but was uncontrolled. The gap between the extensive animal literature and the near-complete absence of human clinical data is the defining feature of BPC-157's evidence base. No established human dosing, safety profile, or pharmacokinetic data exist from rigorous trials. Animal studies have shown no significant toxicity, but this does not guarantee human safety. Products from unregulated sources are not subject to pharmaceutical manufacturing standards, and their composition, purity, and sterility cannot be assured.

Scientific Detail

Overview (Scientific)

BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide (15 AA: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val), MW 1,419.53 Da. Derived from human gastric juice protein. Stable in gastric juice due to 20% proline content. Not approved by any major regulatory agency. No completed human Phase III trials. All efficacy data from animal studies. Available through grey-market suppliers.

Mechanism of Action (Scientific)

Research suggests multiple mechanisms in animal models: upregulation of growth factors (EGF, VEGF, HGF, FGF2), NO system modulation, FAK-paxillin pathway activation in tendon fibroblasts, collagen organization enhancement, dopaminergic/serotonergic system modulation, gastric mucosal cytoprotection via prostaglandin/NO pathways, and anti-inflammatory effects. All mechanisms unvalidated in human trials.

Summary (Scientific)

No marketing authorization. No human Phase III trials. Small pilot (N=4) in UC showed potential but uncontrolled. >100 animal studies (primarily University of Zagreb). Animal data: Achilles tendon tensile strength +84% at 14 days, healed NSAID gastric ulcers, improved spinal cord injury outcomes at 10 mcg/kg. No established human dosing.

Research Compound
Gastric Pentadecapeptide (Alternate Designation)

This entry reflects historical nomenclature for the compound more commonly known as BPC-157. The evidence base, regulatory status, and limitations described for BPC-157 (#81) apply identically to this compound. See compound #81 for the full assessment. No marketing authorisation. No human Phase III trials. No established human dosing or safety profile.

Cartalax

Research Compound
Khavinson Bioregulator Tripeptide (Unregulated)

Cartalax has no marketing authorisation from any major regulatory agency. No human clinical trials have been conducted. The evidence base consists of cell culture studies published by the originating research group. As with other Khavinson bioregulator peptides, the proposed tissue-targeting mechanisms have not been independently validated. Products available through unregulated channels lack pharmaceutical quality assurance.

TB-500

Research Compound
Thymosin Beta-4 Fragment (Unregulated)

TB-500 has no marketing authorisation from any regulatory agency. No human clinical trials of TB-500 specifically have been conducted. The evidence base relies on animal studies of both TB-500 and its parent molecule thymosin beta-4, which are not pharmacologically equivalent. TB-500 is prohibited by WADA and is known from equine and greyhound racing contexts. Products available through unregulated channels lack pharmaceutical quality assurance. The absence of any human safety or efficacy data means that the compound's effects, risks, interactions, and appropriate dosing in humans are unknown.
