How to Reconstitute BPC-157: A Simple Step-by-Step Guide

Jun 11, 2026 1 min Healing & Recovery
TL;DR
Mixing BPC-157 takes four steps: warm the vials, draw BAC water, add it slowly to the powder, and swirl until clear. The calculator on our site converts vial size, water and target dose into exact syringe units. See the cited dosage chart for studied ranges.

What "reconstitution" actually means

BPC-157 ships as a dry powder. Before it can be measured, it has to be dissolved in bacteriostatic water (BAC water). That is all "reconstitution" means — turning the powder into a liquid you can draw into a syringe.

The simple steps

  • Let both vials reach room temperature.
  • Draw your chosen amount of BAC water.
  • Add it slowly down the inside wall of the peptide vial — never spray it directly on the powder.
  • Swirl gently; do not shake. Wait until it is fully clear.

Getting the dose right

The amount you draw depends on the concentration. Instead of doing the algebra, use our reconstitution calculator — enter the vial size, the water, and your target dose, and it tells you exactly how many units to draw. For the studied dose ranges, see the cited BPC-157 dosage chart.

Storing it

Once mixed, keep it refrigerated and use it within the window your supplier specifies. Keep it out of light.

FAQ

What water do you use for BPC-157?
Bacteriostatic water is standard for reconstituting BPC-157 because the small amount of benzyl alcohol helps keep the solution stable for multiple draws.
How much water should I add?
Any amount works — it only changes the concentration. More water means a larger, easier-to-measure draw. Use the calculator to match your target dose.
How long does reconstituted BPC-157 last?
Once mixed and refrigerated, follow your supplier's stated window. Keep it cold and away from light to preserve it.
