How to Reconstitute BPC-157: Step-by-Step Research Protocol

This protocol walks through reconstituting a lyophilized BPC-157 research vial with bacteriostatic water. It is written for laboratory and research use only. It does not constitute medical advice and is not a dosing recommendation.

Materials

1 vial of lyophilized BPC-157 (e.g., 10mg)
Sterile bacteriostatic water (0.9% benzyl alcohol)
1 mL insulin syringe (U-100) with 28–31G needle
Alcohol prep pad
Sterile mixing vial (optional, if transferring)
Refrigerator at 2–8°C for storage

Step 1 — Inspect the vial

Confirm the vial seal is intact. The lyophilized cake should appear as a uniform white or off-white pellet at the bottom of the vial. If the cake is liquefied, discolored, or visibly contaminated, do not use the vial; document the batch number and contact the supplier.

Step 2 — Calculate your reconstitution volume

The volume of bacteriostatic water you add determines the concentration of the reconstituted solution. For research purposes, 2 mL is a common volume for a 10mg vial because it produces clean per-tick math on a U-100 syringe.

Vial	BAC water added	Concentration	Per 10 IU tick (0.10 mL)
10mg BPC-157	1.0 mL	10 mg/mL	1.0 mg
10mg BPC-157	2.0 mL	5 mg/mL	0.5 mg
10mg BPC-157	5.0 mL	2 mg/mL	0.2 mg

Step 3 — Reconstitute

Wipe the rubber stopper of both vials with an alcohol prep pad and allow to dry.
Draw your calculated volume of bacteriostatic water into the insulin syringe.
Insert the needle into the BPC-157 vial at a 45° angle so the water runs down the inside wall rather than directly onto the cake.
Inject slowly. Do not shake. Gently swirl or invert until the cake fully dissolves — typically within 30 seconds. BPC-157 is a small, stable peptide and reconstitutes cleanly.
The solution should appear clear, colorless, and free of particulates.

Step 4 — Label and store

Label the vial with reconstitution date and concentration.
Store at 2–8°C, protected from light.
Use within 30 days at refrigerated storage.
For longer storage, aliquot and freeze at −20°C to minimize freeze–thaw cycles.

Common errors to avoid

Shaking the vial. Vigorous agitation can denature peptide structure. Always swirl or invert.
Using sterile water instead of bacteriostatic. Plain sterile water has no preservative and limits usable life of the reconstituted solution to ~24 hours.
Injecting BAC water directly onto the cake at high pressure. Route water down the inside wall of the vial.
Inconsistent labeling. Always record date, concentration, and lot/batch number for lab records.
