99.258% purity and 11.30 mg measured in a vial labelled 10 mg: those are the headline results of Janoshik task #93626, the third-party report we hold for BPC-157 10mg. The complete document is shown below with its fields written out underneath.

Reading the result
The quantity is about 13% above the declared strength. For anyone preparing stock solutions, that matters more than it first appears: a concentration worked out from the label alone would understate what is actually dissolved, so the measured mass should drive the arithmetic. Our peptide concentration calculator accepts any vial mass.
A purity of 99.258% clears the 99%+ specification we hold. BPC-157 contains several proline residues, and cis–trans isomerism at those residues can broaden or split its main peak on reversed-phase HPLC. The report includes no chromatogram, so peak shape cannot be assessed from it; the effect itself is explained in proline cis–trans peak broadening in BPC-157.
Outside the scope of this report
No method, column or wavelength is printed. Nothing was tested for sterility, endotoxin or residual solvents. The batch is listed as “Unknown”, and the sample is identified through the photographs Janoshik took on receipt (the description reads “See picture or pictures attached”).
Tracing a vial back to this certificate
Rather than printed lot numbers, ExoLabz links each vial to its certificate by cap and crimp colour. Record both colours on arrival, alongside compound and strength, and keep that note in your lab book so a later experiment can be tied back to task #93626.
The laboratory’s own copy can be retrieved at janoshik.com/verify/ with the key KY8VES262D7Z.

Built for Canadian labs that check the data
Packed and handed to the carrier usually within one business day, then tracked across Canada, typically 1 to 4 business days outside the territories.
Independent laboratories run the HPLC and purity work. Certificates live on the certificates page and on selected product pages, and cap and crimp colour ties a vial to its document.
Test a vial yourself. If an independent laboratory reports a purity failure, the product is refunded and the cost of that test comes back with it.
Free over $200 CAD, with no clearance, duty or brokerage anywhere in the country, and quantity pricing applied in the cart.
