Storage & stability How long it lasts, both before and after reconstitution The stability of bacteriostatic water and the reconstituted solution depends on the phase you are in: Unopened vial of bacteriostatic water: Store at room temperature, protected from direct light Shelf life according to the date on the packaging (typically months to years) Peptide reconstituted with bacteriostatic water: Store at 28 C (a standard refrigerator), protected from light Use within 14 to 30 days depending on the specific peptide More sensitive peptides (for example LL-37 or SS-31 ) may have shorter stability, follow the documentation for the given peptide Peptide reconstituted with sterile water without preservative: Substantially shorter shelf life, typically up to 7 days , since protection against microbial growth is absent Practical storage rules Let the vial warm to room temperature before opening (1520 min)
