BPC-157 reconstitution, storage and the lab report
The numbers for BPC-157 in one place: sequence, mass, vial sizes, concentration at common volumes, and what its lab report should show.
Published September 4, 2026
BPC-157 is a 15-residue peptide derived from a sequence found in gastric juice protein, and it is the most-searched compound in this catalog.

Fifteen residues, five of them proline. That proline content is unusual and it is part of why the molecule is stable as a dry powder.
The molecular weight above is the expected mass on a mass-spec result. If a report's observed mass reads 1419.5 or 1419.6, identity has been confirmed. If it reads 1,400 or 1,450, something is wrong regardless of what the purity line says.

BPC-157 vial sizes we sell, at four diluent volumes. Molarity uses 1419.53 g/mol. Other volumes
At 1,419.53 g/mol, a 5 mg vial is about 3.52 micromoles and a 10 mg vial is about 7.04. The calculator has both sizes and the molecular weight preset if you want a volume it does not list.
Handling
Water down the inside of the glass, never onto the powder, then swirl. Shaking foams it and foam means shear. A clean BPC-157 solution is clear and colourless; cloudiness or particles that will not dissolve mean check the report before you go further. Dry powder lives in the freezer at -20°C for months or the fridge for weeks. In solution it lives in the fridge, out of light, and never through a second freeze. The reconstitution guide and storage guide have the detail.
Reading its report
Four things, in this order. The observed mass, which should be 1419.5 g/mol give or take. HPLC purity, which for a batch we ship is 99% or higher. The batch number, which should match the code on the vial. And the name of the lab that ran it.
Every pepuro vial carries a QR code that opens exactly that report. Look up a batch by code if the sticker is damaged. Before you order, the Lab Reports tab on the product page sends you the latest batch's report by email.
The pairing you will see everywhere
BPC-157 and TB-500 appear together constantly in tissue-repair research, which is why we sell them as a blended vial as well as separately. BPC-157 vs TB-500 sets out how the two molecules actually differ, and peptide blends vs single vials covers when the blend is the right call.
Every BPC-157 vial from pepuro ships free, from our Calgary, Toronto and Vancouver distribution centers, the same business day your e-Transfer clears, with a QR code on the vial that opens its independent, third-party lab report.

Frequently asked questions
What is the molecular weight of BPC-157?
+
1419.53 g/mol, formula C62H98N16O22. That is the expected mass a mass-spec result on its lab report should match closely.
How much water do I add to a 5 mg BPC-157 vial?
+
Whatever gives a concentration you can measure. 1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL, 5 mL gives 1 mg/mL. The vial still holds 5 mg whichever you choose.
What is 5 mg of BPC-157 in micromoles?
+
About 3.52 micromoles. Divide 5 mg by 1,419.53 g/mol and multiply by 1,000.
How should BPC-157 be stored?
+
Dry powder in the freezer at -20°C for long-term storage, or the fridge short term. Once reconstituted, refrigerate and avoid freeze-thaw cycles.
