Mass confirmed against the reference molecular weight of 1419.55 g/mol. A peptide can be pure and still be the wrong molecule, so identity is reported on its own line.

BPC-157, a synthetic pentadecapeptide. Sequence GEPPPGKPADDAGLV, molecular weight 1419.55 g/mol, supplied as a sterile lyophilised powder. Purity spec ≥ 98%; this lot returned 99.62%.
Every lot goes to Janoshik, Freedom Diagnostics and Vanguard separately, and all three certificates are published before the batch opens for sale. We also publish the lots that fail, with the assay that failed them.
Let the vial reach room temperature before opening. Add bacteriostatic water down the inside wall, do not inject directly onto the powder, and swirl gently rather than shaking. Members receive Kylo H2O 30 ml with each of their first 10 orders.
Lyophilised vials hold at −20 °C, sealed and away from light. Once reconstituted, hold at 2 to 8 °C and avoid repeated freeze-thaw cycles. Return the vial to cold storage promptly after handling.

From batch to shelf
Most sellers publish a purity number. We publish the document it came from, before the lot is listed. Four steps, in order, every time.
Step 01SampledEvery batch is sampled before a single vial is packed.
Step 02Sent outIt goes to an independent laboratory. We do not test our own product.
Step 03ReportedIdentity, purity and net peptide content, on a signed certificate.
Step 04PublishedThe certificate goes up before the lot is listed. Nothing sells uncertified.
Every certificate carries a search code. Type it into the lab’s own site and it confirms the result without us in the middle.

Every number here is on the certificate for the lot you are buying. Ask whoever you bought from last time for theirs.

If a vial ever arrives that does not match the certificate we published for its lot, we replace it and refund the order. That is the one promise we make about what is inside the vial, and it is the one we can keep.
Risk free
Three promises,each one costs us money.
A guarantee that cannot cost the seller anything is not a guarantee. These can, and that is the point.
The certificate matches, or we payIf a vial ever arrives that does not match the certificate we published for its lot, we replace it or refund it, within 30 days of delivery.
Lost in transit, or it ships againIf the carrier loses your order, we replace it or refund it. Tracking on every order.
Thirty days on the membershipChange your mind about the $497 within 30 days and we refund it in full, as long as you have not used it yet: no member-priced order, no member perk, no credits spent.
Answers
The questions researchersactually ask us.
BPC-157 is a stable synthetic pentadecapeptide studied as a tool compound in tissue-repair and cytoprotection research. In vitro and preclinical work uses it in gastric and intestinal mucosal-injury models, tendon and ligament fibroblast cultures, endothelial angiogenesis assays, and central and peripheral nervous-system injury models, examining nitric-oxide, FAK-paxillin, and growth-factor receptor pathways.
≥99% pure by HPLC-UV — the latest released lot tested 99.62%, with identity confirmed by LC-MS and a measured net peptide content of 12.14 mg in a 10 mg vial. Every lot is released against an independent third-party full QC panel — HPLC purity, LC-MS identity, net peptide content, heavy metals (ICP-MS), sterility, and endotoxin (USP <85>) — with a lot-specific COA matched to the lot number printed on the vial.
The CAS number is 137525-51-0 and the PubChem CID is 9941957. The molecule is also cataloged as Body Protection Compound 157, Pentadecapeptide BPC-157, PL 14736, and Bepecin, with the sequence GEPPPGKPADDAGLV and a molecular weight of 1419.55 g/mol.
Hold the lyophilized vial at −20 °C, sealed and protected from light and moisture. Store sealed aliquots at −20 °C or below for longer storage; avoid repeated freeze-thaw cycles.
No. The research-grade BPC-157 supplied by Kylo Peptides is for in vitro laboratory study only. It is not formulated, packaged, or labeled for human or veterinary use.
Yes. The lot-specific Certificate of Analysis is published in our public COA library and matched to the lot ID printed on the vial, covering HPLC purity, LC-MS identity, net peptide content, heavy metals (ICP-MS), sterility, and endotoxin (USP <85>) from an independent third-party laboratory.
