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.

Identity

| Formula | C62H98N16O22 |

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.
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 Calgary, the same business day your e-Transfer clears, with a QR code on the vial that opens its Janoshik Analytical 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.
