Research handling note: bring both the peptide and your selected solvent to standard laboratory room temperature before reconstitution to preserve structural integrity. Reconstitution solutions are sold separately.
About Bacteriostatic Water
0.9% benzyl alcohol sterile diluent for peptide reconstitution.
Usage & Storage
Supplied as a lyophilised solid for maximum stability. Store unopened at −20°C for long-term stability; reconstituted solution is generally stable at 2–8°C for up to 28 days under sterile handling.
Quality Assurance
Each batch is synthesised under strict QC and verified by HPLC for identity and purity. A batch-specific Certificate of Analysis is available on request.

Frequently asked questions.
Can lyophilised vials be frozen?
Long-term frozen storage (-20°C) is acceptable for lyophilised vials, but routine refrigerated storage at 2–8°C is sufficient for typical research timelines.
