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

Written by dr-sarah-chen|Updated 2026-03-25|2 min read

Reconstituting lyophilized (freeze-dried) peptides is one of the most common questions we receive. This guide walks you through the exact process for BPC-157.

What You Will Need

  • BPC-157 lyophilized vial (5mg)
  • Bacteriostatic water (BAC water) — NOT sterile water
  • Insulin syringe (1mL)
  • Alcohol swabs

Step-by-Step Instructions

Step 1: Gather Your Supplies

Ensure everything is clean and at room temperature. Wash your hands thoroughly.

Step 2: Prepare the BAC Water

Wipe the top of the bacteriostatic water vial with an alcohol swab. Draw 2mL of BAC water into your insulin syringe.

Step 3: Add Water to the Peptide Vial

Wipe the top of the BPC-157 vial with an alcohol swab. Slowly inject the 2mL of BAC water into the vial, aiming the stream at the glass wall — not directly at the powder. Let it drip down gently.

Step 4: Mix Gently

Do NOT shake the vial. Instead, gently swirl it or roll it between your palms until the powder is fully dissolved. The solution should be clear.

Step 5: Store Properly

Store the reconstituted vial in the refrigerator at 2-8°C. Use within 30 days.

Dosing Calculation

With 5mg in 2mL of water, your concentration is 2,500mcg/mL. For a 250mcg dose, you would draw 10 units on a 100-unit insulin syringe (0.1mL).
