BPC-157

BPC-157 is a synthetic pentadecapeptide consisting of 15 amino acids (sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val), derived from a protective protein found in gastric juice. In preclinical research, BPC-157 has been studied for its effects on tissue repair and angiogenesis, gastrointestinal tract function and gut-brain signalling, tendon-to-bone healing models, and anti-inflammatory pathway modulation. It is one of the most extensively researched tissue-repair peptides with a large body of published rodent studies. Molecular weight: 1419.53 Da. Supplied at 99.815% HPLC purity.

BPC-157 and TB-500 are structurally unrelated peptides that have been studied in overlapping but distinct tissue repair contexts. BPC-157 acts via pathways involving nitric oxide, VEGFR2, and the FAK-paxillin pathway. TB-500 is thought to work primarily through actin binding and cell migration promotion. Because their proposed mechanisms differ, combining them in research has become common practice — which is why we offer a pre-blended BPC-157 + TB-500 Blend (5mg each, 10mg total) for researchers requiring both in a single preparation.

Reconstitution: Using a clean 31G insulin syringe, draw 1–2mL of bacteriostatic water. Inject slowly down the inside glass wall of the BPC-157 vial. Gently swirl until fully dissolved — do not shake, vortex, or invert aggressively. The solution should be clear and colourless. Common concentration: 1mL bacteriostatic water into 10mg = 10mg/mL; 2mL = 5mg/mL. Storage: Lyophilised — store at −20°C for up to 24 months. Reconstituted — refrigerate at 2–8°C and use within 4 weeks. Protect from light throughout.

Legal status: BPC-157 is legal to purchase in Australia for laboratory research purposes. It is not listed as a scheduled substance under the Poisons Standard when sold for research use only. Purchasers must be 18+ and confirm research-only use. It is not TGA-approved for human consumption, therapeutic, cosmetic, or veterinary use. Quality: Our BPC-157 10mg (Batch PW-260308) is independently verified at 99.2% HPLC purity. COA includes HPLC purity %, mass spectrometry identity confirmation (MW 1419.53 Da, C62H98N16O22), and sterility screening. Full COA is publicly available in our COA Library.

BPC-157 and GHRP-6 are structurally and mechanistically unrelated. GHRP-6 (Growth Hormone Releasing Peptide-6) is a hexapeptide ghrelin mimetic that stimulates GH secretion via the GHS-R1a receptor — its primary research applications involve the GH/IGF-1 axis. BPC-157 does not act on GHS-R1a and does not directly stimulate growth hormone release. Instead, BPC-157's research profile centres on local tissue repair, angiogenesis, and gut protective mechanisms. The two peptides target completely different receptor systems and are not interchangeable research tools. Not for human consumption — for research use only.

TB-500 (thymosin beta-4 fragment, sequence Ac-LKKTETQ) primarily acts by sequestering actin monomers (G-actin), promoting cell migration and tissue remodelling at a cytoskeletal level. It is also studied for its effects on systemic inflammation and cardiac tissue models. BPC-157, by contrast, is more focused on local angiogenesis, nitric oxide modulation, and gastrointestinal protective mechanisms. TB-500 has broader systemic distribution properties in animal models, while BPC-157 is more frequently studied in localised tendon, ligament, and gut tissue contexts. For research requiring both mechanisms, our BPC-157 + TB-500 Blend at /products/bpc-157-tb-500-blend provides both at 5mg each in a single vial. Not for human consumption — for research use only.

BPC-157 is a stable gastric pentadecapeptide, and a notable feature of the research literature is that it has been studied via both systemic and oral routes in animal models — its reported stability in gastric juice is part of why oral-route research exists. The route used is determined entirely by the experimental protocol. Not for human consumption — for research use only.

Preclinical research has examined BPC-157 in the context of angiogenesis and growth-factor signalling, including VEGF-related pathways and the formation of new blood vessels in tissue-repair models. This vascular angle is one proposed mechanism behind its studied effects in tissue-repair models across multiple tissue types. Not for human consumption — for research use only.

BPC-157 appears in preclinical literature across tendon, ligament, muscle, bone and gastrointestinal tissue models, as well as nervous-system studies. The breadth of tissue models is a defining feature of the compound's research profile. All findings are from research settings and do not constitute evidence of human benefit. Not for human consumption — for research use only.

Beyond tissue repair, BPC-157 has been investigated in preclinical models touching the gut-brain axis and neuroprotection, including studies on neurotransmitter systems and nerve injury. These are exploratory research directions in the literature rather than established mechanisms. Not for human consumption — for research use only.

Lyophilised BPC-157 stores well at −20°C for up to 24 months. After reconstitution in bacteriostatic water, refrigerate at 2–8°C and use within about 4 weeks, protected from light and away from repeated freeze-thaw cycles. Its relative stability is one reason it is a widely used research peptide. Not for human consumption — for research use only.

BPC-157 stands for Body Protective Compound 157. It is a pentadecapeptide (a 15-amino-acid chain) and is sometimes written BPC157 or, by autocorrect, PBC-157. All of these refer to the same tissue-repair research peptide. For in-vitro research use only.
