BPC-157 Spray

The row below carries a price per mg figure: listed price divided by stated peptide content, excluding shipping and codes. It is the same calculation applied on every compound page, so a figure here is directly comparable to one anywhere else on the site.

We currently track a single listing for this compound. When a second vendor is added the rows are ordered by measured $/mg, and the flags for testing and shipping are computed from the data shown. Each row carries its own verification date.

Body Protection Compound-157 — extensively researched for tissue repair, tendon/ligament healing, and gut protection.

A 15-residue synthetic peptide derived from a sequence in human gastric juice, extensively characterised in preclinical wound-healing and tissue-integrity models. For laboratory characterisation only.

BPC-157 is a synthetic 15-amino-acid peptide derived from a gastric protective protein. As of 2026, only 3 published human studies exist (all pilot-scale with <30 subjects), but 500+ preclinical studies show tissue healing effects. A 2025 IV safety study (up to 20mg) in healthy adults showed no adverse events across cardiac, hepatic, and renal biomarkers. It has a molecular formula C62H98N16O22, mass 1419.53 Da. Its published amino-acid sequence is Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. Common synonyms in the literature include Body Protection Compound-157, Bepecin, and PL 14736.

Investigation of BPC-157 to date is primarily preclinical, with the majority of citations concentrated in animal models and in-vitro assays rather than randomized controlled human trials. Published work referencing BPC-157 spans In-vitro cell culture studies: BPC-157 has been examined in fibroblast, endothelial cell, and smooth muscle cell lines to observe effects on cell migration, proliferation, oxidative stress responses, and signaling pathway activation. These controlled experiments provide mechanistic insight at the cellular level but do not fully represent complex whole-organism physiology, Tendon and ligament models: Rodent studies have investigated BPC-157 in surgically induced or chemically induced tendon injuries, including Achilles tendon transection models. Researchers have reported observations on healing timelines, collagen fiber alignment, tensile strength measurements, and histological markers of tissue maturation, and Musculoskeletal injury research: Animal studies have explored BPC-157 in crushed muscle and transected muscle paradigms, with observations reported on fibroblast survival, cell migration, biomechanical recovery metrics, and regeneration markers. Proposed mechanisms in the literature include VEGF and angiogenesis: upregulates VEGF expression in vivo, activates VEGFR2 receptors on endothelial cells, triggers Akt-eNOS pathway phosphorylation and Nitric oxide modulation: enhances endothelial NOS (eNOS) activity via Src-Cav-1-eNOS pathways, influences NO synthase activity and vascular tone. None of this material describes therapeutic outcomes in humans, and No vendor listed here provides dosing guidance for BPC-157 outside laboratory research.

BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide derived from a protective protein found naturally in human gastric juice. Consisting of 15 amino acids with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, BPC-157 has emerged as one of the most extensively researched peptides in cellular-pathway research. Originally isolated by Professor Predrag Sikiric at the University of Zagreb, this peptide has been the subject of numerous preclinical investigations examining its potential protective and cellular-pathway properties in various tissue types.

BPC-157's biological activity involves multiple interacting pathways that researchers believe contribute to its observed effects in experimental models:

Gastrointestinal Studies. BPC-157 was originally studied for its gastric protective properties. Research has examined its effects on various GI conditions in animal models, including gastric ulcers, inflammatory bowel conditions, and esophageal damage. Studies suggest it may promote mucosal integrity and accelerate healing in damaged GI tissue.

Musculoskeletal Research. Extensive preclinical studies have investigated BPC-157's effects on tendons, ligaments, and muscle tissue. Research in rat models has shown accelerated healing of transected Achilles tendons, quadriceps muscles, and various ligaments. Studies suggest enhanced collagen organization and accelerated functional recovery.

Wound-Model Research. Research has examined BPC-157's effects on various wound types, including burns, incisions, and diabetic wounds. Studies report enhanced angiogenesis (blood vessel formation), accelerated granulation tissue formation, and improved wound closure rates in experimental models.

Neurological Research. Emerging research has explored BPC-157's potential neuroprotective properties. Studies in animal models have examined effects on peripheral nerve injuries, traumatic brain injury, and various neurotoxicity models. Some research suggests potential dopaminergic system interactions.
