BPC-157 Purity & COA Verification
For laboratory research use only. Not for human consumption, diagnosis, or treatment.
BPC-157 COA and third-party testing
Every BPC-157 batch is independently analysed before release. HPLC measures purity against a ≥99% standard, mass spectrometry confirms molecular identity, and the published panel records heavy-metals, endotoxin and sterility screening where applicable. The third-party report is tied to the batch number printed on the vial, so a third-party tested BPC-157 result can be verified at source rather than taken from a summary claim.
Testing documentation is supplied for laboratory research use only and does not support human, veterinary, diagnostic or therapeutic use.
What is BPC-157?
BPC-157 is a synthetic peptide fragment of a sequence described in the literature as Body Protection Compound, a protein sequence originally identified in gastric juice. The designation refers to a 15-amino-acid chain reproduced by solid-phase peptide synthesis rather than extracted from tissue.
Published BPC-157 research is preclinical and has examined tissue-repair and gastrointestinal-related endpoints in controlled laboratory models. Reported lines of investigation include angiogenesis markers, nitric-oxide pathway signalling, and connective-tissue and gastrointestinal-mucosa repair measures. These describe measurements recorded in experimental models only; they do not establish an effect, benefit or suitability for any person.
Ares Research supplies BPC-157 as analytical research material with batch-linked documentation, which is the format laboratories generally require when qualifying a peptide as a comparison or reference material.

BPC-157 research questions
+What is BPC-157?
BPC-157 is a synthetic peptide fragment derived from a sequence described in the literature as Body Protection Compound, a protein sequence identified in gastric juice. It is a short 15-amino-acid chain and is supplied by Ares Research strictly as laboratory research material, not for human or veterinary use.
+What has published BPC-157 research examined?
Published preclinical literature on BPC-157 has examined tissue-repair and gastrointestinal-related endpoints in controlled laboratory models, including angiogenesis markers, nitric-oxide pathway signalling and connective-tissue repair measures. These are recorded research observations in experimental models only and do not describe an outcome for any person.
+Is your BPC-157 third-party tested, and can I see the COA?
Yes. Every BPC-157 batch is independently analysed before release, and the Certificate of Analysis is tied to the batch number printed on the vial. You can look up the batch COA through the Ares Research COA lookup and review the published purity record on the transparency page.
+What purity standard does Ares Research BPC-157 meet?
BPC-157 is produced to a ≥99% purity standard, with purity measured by HPLC and molecular identity confirmed by mass spectrometry. The third-party panel also covers heavy metals, endotoxins and sterility where applicable.
+Can BPC-157 be used as a reference material?
Each vial is supplied with batch-linked analytical documentation, which is what laboratories typically require when qualifying a peptide as a comparison or reference material. Suitability for any specific analytical method remains the responsibility of the receiving laboratory.
+How is BPC-157 shipped?
BPC-157 is shipped domestically from the United States with tracked delivery. Vials are packed to protect the lyophilised material in transit and are supplied exclusively for laboratory research use.
+How should BPC-157 be stored?
Keep sealed lyophilised vials refrigerated and protected from light and moisture. After laboratory reconstitution, keep the material refrigerated and follow the handling documentation supplied with the batch.

Analytical Testing Panel
Verified by Janoshik Analytical — full panel, every batch. Second independent lab confirmation is being added batch by batch.
Quantifies the main peak against related-substance peaks, so the stated purity percentage is measured rather than assumed.
Every BPC-157 lot passes all 8 stages before it is released. Expand a stage to see the method and why we run it.
- Method on the COARP-HPLC (UV 214 nm)Why Ares runs it
Quantifies the main peak against related-substance peaks, so the stated purity percentage is measured rather than assumed.
- Method on the COAQuantitative HPLC mass/concentration assayWhy Ares runs it
Confirms the vial actually contains the labeled amount — purity alone says nothing about how much material is in the vial.
- Method on the COAMass Spectrometry (ESI-MS)Why Ares runs it
Confirms the measured molecular mass matches the declared compound — the check that catches a mislabeled or substituted vial.
- Method on the COAICP-MSWhy Ares runs it
Screens for elemental contaminants carried over from synthesis, reagents, or packaging.
- Method on the COAMembrane filtration, USP <71> methodologyWhy Ares runs it
Checks the finished lyophilized vial for microbial growth after fill and closure.
- Method on the COALAL assay (kinetic chromogenic)Why Ares runs it
Measures bacterial endotoxin load, a contamination marker that purity testing alone will not reveal.
- Method on the COAIndependent batch review against release specificationWhy Ares runs it
Ties the analytical numbers back to the paperwork — the lot you receive is the lot on the certificate.
- Method on the COALC-MS/MS targeted screenWhy Ares runs it
A contamination check most research suppliers never run, and the reason we run it on every batch regardless of compound.
PASS reflects the batch release standard every lot must meet before it ships. Per-lot results are published on that lot's Certificate of Analysis.
