Research Disclaimer: BPC-157 is sold by Palmetto Peptides strictly as a research compound for in vitro and laboratory use only. It is not intended for human or veterinary consumption, administration, or therapeutic use.

BPC-157 is one of the most extensively studied synthetic peptides in preclinical research. Researchers can order BPC-157 research peptide from Palmetto Peptides with full lot-specific COA documentation. For combined tissue repair research, the BPC-157 + TB-500 Wolverine Stack is also available.

What Is BPC-157?

BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide — a 15-amino acid sequence — derived from a region of the human gastric juice protein BPC. The peptide sequence is Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. It has no known endogenous receptor and does not correspond to any naturally occurring full-length protein fragment. Its effects in laboratory models have been studied across an unusually wide range of tissue systems for a single research compound.

Mechanism of Action in Laboratory Models

BPC-157 does not operate through a single defined molecular mechanism. Laboratory research has identified several proposed pathways:

Nitric oxide (NO) system modulation: Multiple studies implicate the NO pathway as a central mediator, particularly in GI and vascular research models
Growth factor receptor upregulation: Studies have reported increases in VEGFR2 and FGFR expression in BPC-157 treated tissues in rodent models
Tendon fibroblast activity: In vitro studies show effects on tendon fibroblast migration and collagen organization
Dopamine system interaction: Rodent behavioral models have examined BPC-157 effects on dopamine receptor activity

Key Research Areas

Gastrointestinal Research

The earliest and most extensive BPC-157 research is in GI models. Studies in rat models of gastric ulceration, colitis, and intestinal fistula repair have consistently documented accelerated healing endpoints in BPC-157 treated groups. The compound's apparent oral activity in rodent models — unusual for a peptide — has attracted particular research interest.

Tendon and Musculoskeletal Models

Preclinical tendon transection studies in rats have shown accelerated collagen organization and biomechanical recovery in BPC-157 treated tendons. This research area is often studied in combination with TB-500 (Thymosin Beta-4), which works through a different mechanism (actin regulation). See the Wolverine Stack research guide for combined protocol context.

Neurological Models

More recent preclinical studies have explored BPC-157 in neurological injury models including traumatic brain injury and spinal cord research, as well as dopamine system dysregulation models in rodents.

Systemic Cytoprotection

BPC-157 has been studied in multiple organ protection models — including heart, liver, kidney, and lung — in response to various chemical and mechanical stressors in rodent systems.

Purity and Quality Standards for BPC-157 Research

Research-grade BPC-157 requires: HPLC purity of 98% or above, lot-specific mass spectrometry identity confirmation (expected MW: 1419.56 g/mol), and peptide content percentage reported separately. Palmetto Peptides provides full COA documentation for every lot. Related reading: research peptide purity testing standards and GHK-Cu research guide.

Reconstitution and Storage

BPC-157 reconstitutes readily in bacteriostatic water or sterile PBS at pH 7.4. Standard stock concentration: 1–2 mg/mL. Store lyophilized powder at -20°C desiccated dark (stable 24+ months). Reconstituted stocks at -80°C in single-use aliquots (stable 6–12 months). Maximum 3 freeze-thaw cycles.

Frequently Asked Questions

Is BPC-157 approved for human use?

No. BPC-157 has not received FDA approval for any human therapeutic indication. It is available strictly as a research compound for qualified laboratory use.

What is the molecular weight of BPC-157?

Approximately 1419.56 g/mol. Molecular formula: C62H98N16O22.

How does BPC-157 differ from TB-500?

BPC-157 and TB-500 (Thymosin Beta-4) are structurally unrelated peptides that work through different mechanisms. BPC-157 operates primarily through the NO system and growth factor receptor pathways; TB-500 works through actin regulation and cell motility. They are frequently studied together in combined tissue repair models.
