What is BPC-157?

Origin and sequence

BPC-157 is the shorthand for a synthetic peptide derived from a larger protein known as Body Protection Compound, originally identified in human gastric juice. The synthetic analog used in research is a 15-amino-acid sequence — small enough to manufacture via solid-phase peptide synthesis at commercial scale, and stable enough to lyophilize and ship as a dry reference standard.

The molecule is a reference standard: a known, pure sample that laboratories use to calibrate assays, run comparative experiments, and validate analytical methods. It is not a therapeutic product.

How to evaluate a supplier

When sourcing BPC-157 for laboratory research in Canada, three documents matter more than the price:

1. Certificate of Analysis (COA) — per-lot HPLC purity, mass-spec identity, and LAL endotoxin assay. The minimum standard is ≥99% HPLC purity for reference work.
2. Chain of custody — where was it synthesized, which lot, what date. A supplier that can't answer those questions cannot give you reproducible data.
3. Storage and shipping conditions — lyophilized peptides are stable for years. In transit, they benefit from cold-pack protection and temperature logging. Ambient shipping degrades potency.

Pure North Peptides' approach

Every BPC-157 lot at Pure North Peptides is synthesized at a contract laboratory and independently verified by Janoshik Analytical, independently verified on arrival via HPLC, mass spectrometry, and LAL assay, and stored until shipment. The COA is issued per lot and matched to the vial label. Orders are dispatched within 2 business days, with Canada Post Xpresspost transit averaging around 4 days across Canada.

All products are sold strictly as laboratory reference standards. They are not approved drugs and are not intended for therapeutic use.

Common questions

Is BPC-157 legal to purchase in Canada for research?

BPC-157 is not an approved drug in Canada. It may be sold as a research reference standard for laboratory research only. It cannot be marketed as a therapeutic drug. Pure North Peptides requires a research-use declaration on every order.

What purity should I look for?

For research reference work, ≥99% HPLC purity is the standard. Anything lower introduces measurable analytical noise. Pure North Peptides publishes HPLC chromatograms on every lot COA.

Shelf life and storage?

Lyophilized BPC-157 is stable for 24+ months in sealed, inert-gas-flushed vials. Post-handling stability is outside the scope of a laboratory reference standard — reference your own experimental protocol and internal SOPs.
