BPC-157 Reconstitution Calculator
BPC-157 is a synthetic peptide based on a partial sequence related to a gastric protein. This page shows how to reconstitute it and read the result on a syringe — the calculator does the arithmetic for you.
Status: Not approved for human use; sold as a research compound.
The math
Concentration = vial ÷ water · Units = (dose ÷ concentration) × 100
BPC-157 is one of the most common research peptides. It dissolves in bacteriostatic water; pick a water volume that makes your intended draw easy to read.

Frequently asked questions
How do I reconstitute BPC-157?
Add bacteriostatic water to the lyophilized vial to reach a concentration you can measure. For example, 5 mg in 2 mL of water gives 2.5 mg/mL, so each 10 units (0.1 mL) on a U-100 syringe contains about 250 mcg of BPC-157. Swirl gently rather than shaking.
How many units of BPC-157 do I draw?
Divide your intended dose by the concentration to get the volume in mL, then multiply by 100 for a U-100 syringe. The calculator does this automatically once you enter your vial size, water volume and dose.
What vial sizes does BPC-157 come in?
BPC-157 is commonly supplied as 5 mg, 10 mg. The amount in the vial does not change with how much water you add — water only sets the concentration.
Is BPC-157 approved for human use?
Not approved for human use; sold as a research compound. This calculator only performs arithmetic on the numbers you enter and does not recommend any dose.
