What Lyophilized Means
Lyophilized means freeze-dried. The peptide is dried into a stable powder so it can be shipped and stored, and it is reconstituted in a sterile solvent before laboratory use. The amount in a vial is small, so the powder may look like a thin film or a tiny cake. This is normal.
How to Reconstitute BPC-157 with Bacteriostatic Water
Standard laboratory practice for lyophilized peptides applies. Bacteriostatic water is commonly used as the solvent.
- Let the vial reach room temperature before opening.
- Use sterile technique and sterile bacteriostatic water.
- Add the solvent slowly down the vial wall.
- Swirl gently until dissolved. Do not shake.
- Label the vial with the date, solvent and final concentration.
Reconstitution Volumes
Concentration is the amount of peptide divided by the volume of solvent. Choose the volume that suits your protocol.
| Vial contents | Bacteriostatic water | Final concentration |
|---|---|---|
| 5 mg | 1 mL | 5 mg/mL |
| 5 mg | 2 mL | 2.5 mg/mL |
| 10 mg | 1 mL | 10 mg/mL |
| 10 mg | 2 mL | 5 mg/mL |
How to Store BPC-157: Storage and Shelf Life
- Lyophilized powder: keep the sealed vial cool, dry and away from light. Long-term storage at -20 °C is typical.
- After reconstitution: keep it refrigerated and use it within the period set by your protocol.
- Avoid repeated freeze-thaw cycles, moisture and heat.
How We Test BPC-157
