What is BPC-157?
BPC-157 — formally Body Protection Compound-157 — is a synthetic pentadecapeptide consisting of 15 amino acids derived from a protein naturally present in gastric juice. The sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val is a partial sequence of the endogenous gastric protein BPC, isolated and investigated across a large body of preclinical research literature spanning more than three decades.
One of the distinguishing physical characteristics of BPC-157 is its stability in gastric acid — demonstrated to remain intact for over 24 hours in simulated gastric conditions. This property has made it a frequent subject of gastrointestinal and systemic tissue research where oral or parenteral administration routes are modelled in preclinical settings.
ClaraScience supplies BPC-157 as a lyophilised (freeze-dried) powder in 10mg vials. Each batch is independently HPLC-tested at a WHO/GMP-certified analytical laboratory, with purity consistently verified at 99.3%. A full Certificate of Analysis (COA) including HPLC chromatogram and mass spectrometry identity confirmation accompanies every order. All products are supplied strictly for laboratory research use only and are not intended for human or animal consumption.

Research Background
BPC-157 is among the most cited synthetic peptides in preclinical tissue repair literature. The foundational research programme was established by Professor Predrag Sikirić and colleagues at the University of Zagreb, whose work on the peptide's gastric cytoprotective properties and systemic tissue signalling has been published across peer-reviewed journals since the 1990s.
A 2018 comprehensive review by Sikirić et al. in Current Pharmaceutical Design (24:2002–2030) catalogued observations across over 100 preclinical models, covering gastrointestinal, musculoskeletal, nervous system, and vascular tissue contexts. The peptide has been observed to interact with several growth factor systems and receptor pathways including VEGFR2, EGF receptor signalling, and nitric oxide pathways in rodent model research.
BPC-157 is often studied in combination with TB-500 (Thymosin Beta-4 fragment) in preclinical tissue repair research programmes, as the two compounds exhibit complementary mechanisms at the cellular level — BPC-157 primarily acting through local signalling cascades while TB-500 facilitates actin polymerisation and cell migration at a broader systemic level.
Research into BPC-157 remains exclusively preclinical. No approved therapeutic applications exist, and ClaraScience supplies it solely for legitimate in-vitro and preclinical laboratory research purposes.

Storage & Handling Guidelines
BPC-157 is supplied as a lyophilised powder, which is the most stable form for long-distance shipment and extended storage. ClaraScience ships all peptides in plain, discreet packaging from our Australian warehouse.
Recommended storage conditions
- Unopened lyophilised vial: 2–8°C (refrigerator) for regular use; −20°C (freezer) for storage beyond 3 months.
- After reconstitution: Store at 2–8°C. Use within 28 days. Do not freeze reconstituted solution.
- Light protection: Keep vials away from direct light. Store in the original sealed vial until use.
- Reconstitution solvent: Use sterile bacteriostatic water (0.9% benzyl alcohol) for reconstitution. Use our free reconstitution calculator to determine the exact volume required.
For full storage and handling protocols including freeze-thaw management, temperature logging, and receipt inspection, refer to our Storage & Handling Guide.

Frequently Asked Questions
What is BPC-157?
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide comprising 15 amino acids. It is derived from a partial sequence of a protein found in gastric juice and has been the subject of extensive preclinical research into tissue signalling and repair mechanisms. All ClaraScience products are for laboratory research use only.
Is BPC-157 available to buy in Australia?
ClaraScience supplies BPC-157 as a research-grade peptide from an Australian warehouse. Products are supplied for research use only and have not been evaluated or approved by the Therapeutic Goods Administration (TGA) for any therapeutic purpose. Buyers confirm research-only use at purchase.
What purity is your BPC-157?
ClaraScience BPC-157 is independently tested by a WHO/GMP-certified third-party laboratory and verified at ≥99.3% purity by HPLC. A full COA including HPLC chromatogram and mass spectrometry identity confirmation is included with every order.
How long does shipping take in Australia?
Orders are dispatched from our Australian warehouse within 24 hours of payment confirmation. Delivery typically takes 1–3 business days depending on your location within Australia. All orders include tracked priority shipping. Orders over $250 AUD receive free shipping.
What is the difference between BPC-157 and TB-500?
BPC-157 is a 15-amino-acid gastric pentadecapeptide studied for local tissue signalling effects, while TB-500 (Thymosin Beta-4 fragment) is a 43-amino-acid peptide studied for its role in actin polymerisation and systemic cell migration. The two compounds target different mechanisms and are frequently studied together in preclinical tissue repair research. Both are available at ClaraScience.
Do I need bacteriostatic water to reconstitute BPC-157?
Yes. BPC-157 is supplied as a lyophilised powder that must be reconstituted with sterile bacteriostatic water (0.9% benzyl alcohol) before use in research applications. ClaraScience supplies bacteriostatic water separately, and our free reconstitution calculator will determine the exact volume needed based on your target concentration.
Can I order BPC-157 in bulk?
Yes. ClaraScience offers bulk pricing tiers: 5+ vials at $69.95 each, and 10+ vials at $59.95 each. For institutional or larger-volume requirements, submit a wholesale enquiry.
