- What you reconstitute your peptide with is just as important as how you store it afterward. The choice of solvent directly influences the stability and lifespan of the solution. Our experience shows that for the vast majority of research applications, there's one clear winner. But let's break down the options.
- Bacteriostatic Water
- General multi-use research
- Up to 4 weeks
- Contains 0.9% benzyl alcohol as a preservative. This is the industry standard.
- Sterile Water
- Single-use or immediate use
- 24-48 hours maximum
- Lacks a preservative, making it highly susceptible to contamination.
- Acetic Acid (0.6%)
- Peptides with solubility issues
- Varies; can be unstable
- Can alter peptide structure and pH. For advanced applications only.
- As the table makes clear, Bacteriostatic Water is what we recommend for reconstituting BPC 157. The 0.9% benzyl alcohol it contains is a bacteriostatic agent, meaning it prevents bacteria from reproducing. This is a critical safeguard for a multi-use vial that will be punctured repeatedly over several weeks. Sterile water, lacking this preservative, becomes a prime breeding ground for contaminants after the first use. Its shelf life is measured in hours, not weeks. Acetic acid is a specialized tool for peptides that won't dissolve in water, but it's not necessary for BPC 157 and can introduce its own complications.
