What is BPC-157?

A plain-English primer on the 15-amino-acid partial sequence that has become a staple of musculoskeletal and gastrointestinal research, written for Canadian lab teams sourcing reference standards for the first time.

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. Read the original report for the named sample: area purity and measured content are separate results. The published CPT set does not include endotoxin or mass-spectrometry identity testing.
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

Pure North publishes laboratory reports for the samples and vial sizes listed in Lab Results. Each report identifies its method, reference, area purity and measured content. Open the matching product page to check coverage for the size you select. A report does not cover every size or future lot; contact customer service if your vial reference differs. Bacteriostatic water has no COA.

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?

Pure North publishes laboratory reports for the samples and vial sizes listed in Lab Results. Each report identifies its method, reference, area purity and measured content. Open the matching product page to check coverage for the size you select. A report does not cover every size or future lot; contact customer service if your vial reference differs. Bacteriostatic water has no 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.
