BPC-157 reconstitution calculator
BPC-157 ships as 5 mg, 10 mg vials of lyophilized powder. Pick the size, type the water volume, read the concentration. The molecular weight is already filled in, so the molar result is there too.

What the numbers mean for BPC-157
BPC-157 has a molecular weight of 1419.53 g/mol (C62H98N16O22). So 5 mg is about 3.52 micromoles, whatever volume you dissolve it in. At 2.5 mg/mL that is 1.76 mM.
Sequence: GEPPPGKPADDAGLV. The expected mass on the vial's mass-spec result is the molecular weight above; a match within a tenth of a percent is the identity check passing.
Each vial holds only powder, from 5 mg up to 10 mg, and no diluent. Add bacteriostatic water down the inside of the glass, swirl, and do not shake. The reconstitution guide covers the handling; this page covers the arithmetic.
Common questions
How much water do I add to a 5 mg vial of BPC-157?+
Any volume that gives a concentration you can measure easily. 1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL, 5 mL gives 1 mg/mL. The peptide amount stays 5 mg whatever you add.
What is the concentration of BPC-157 5 mg in 2 mL?+
2.5 mg/mL, which is the same as 2.5 µg/µL. With a molecular weight of 1419.53 g/mol that is 1.76 mM.
Which BPC-157 vial sizes does the calculator cover?+
The ones we sell: 5 mg, 10 mg. Pick a chip or type any other mass.
Where does the BPC-157 molecular weight come from?+
The reference value on the product's Specifications tab, 1419.53 g/mol. The observed mass for the vial you receive is on its own lab report, which the QR code on the vial opens.
