How to Read a BPC-157 Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For BPC-157, the informative checks are not the same as for a generic short peptide.
In plain English
Check the weight on the report matches about 1419.5. One thing people miss: it is supplied as a salt, so the actual peptide content by weight can be lower than the number on the label. If a report separates "purity" from "peptide content", the second figure is the one to use for accurate strength calculations.
What BPC-157 actually is
BPC-157 is a short chain of fifteen amino acids originally identified in stomach fluid — an environment whose whole chemical job is to break proteins apart. It got attention precisely because it survived that. In research it is studied around how new blood vessels form and how repair signals travel through tissue.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Assays that are informative for BPC-157
What to check on the COA
Confirm the observed mass matches 1419.5 Da for the free peptide. Because BPC-157 is supplied as an acetate salt, net peptide content can sit meaningfully below the gross vial mass — check whether the COA reports peptide content separately from purity, since a 99% pure vial is not the same as a vial that is 99% peptide by weight.
Deletion sequences from incomplete coupling at the consecutive proline residues are the characteristic synthesis-related impurity for this molecule; they elute close to the main peak on RP-HPLC.
