BPC-157 # How to Reconstitute BPC-157 Pre-filled calculator with standard defaults for BPC-157: 5 mg vial in 2 ml BAC water. ## Standard BPC-157 Reconstitution Protocol Add **2 ml** of bacteriostatic water to a **5 mg** vial of BPC-157. This gives a concentration of **2.50 mg/ml**. A **250 mcg** amount measures about **10.0 IU** on a U-100 syringe scale. Store refrigerated at 2–8°C and use within **28 days**.

This tool performs reconstitution math (concentration and syringe-unit conversion) and is not dosing guidance for humans or animals. ## BPC-157 Reconstitution Chart Common syringe draws at the standard BPC-157 preset (5 mg in 2 mL BAC water = 2.50 mg/mL). Units are on a **U-100** syringe scale (100 units = 1 mL). For laboratory research reference only. Syringe units (U-100) Volume Amount (BPC-157) 5 units 0.05 mL 125 mcg 10 units 0.10 mL 250 mcg 15 units 0.15 mL 375 mcg 20 units 0.20 mL 500 mcg 25 units 0.25 mL 625 mcg 30 units 0.30 mL 750 mcg 40 units 0.40 mL 1.00 mg 50 units 0.50 mL 1.25 mg Change the vial size or BAC water above to recompute the chart for a different BPC-157 preset. This chart shows reconstitution math, not a usage recommendation. ## Step-by-Step: How to Reconstitute BPC-157 1. 1 Gather your supplies A sealed 5 mg vial of BPC-157, a vial of bacteriostatic water, a 1 ml U-100 syringe, and an alcohol swab. 2. 2 Add the water Wipe both vial stoppers with alcohol. Draw 2 ml of BAC water into the syringe and release it slowly down the inside wall of the BPC-157 vial. Never spray directly onto the powder — the force can damage the peptide. 3. 3 Swirl gently Gently swirl the vial in a circular motion until the BPC-157 fully dissolves. Do not shake. The solution should become clear. 4. 4 Calculate the amount At a concentration of 2.50 mg/ml, a 250 mcg (0.250 mg) amount equals about 10.0 IU on a U-100 syringe scale. 5. 5 Draw and store Draw the amount you need, then immediately return the vial to the refrigerator at 2–8°C. Use the reconstituted vial within 28 days. These defaults reflect commonly referenced reconstitution presets for BPC-157. Individual research setups may differ. Always verify the concentration against your source and its certificate of analysis.
