Storage & handling
Research peptides ship as a lyophilized (freeze-dried) powder. Before reconstitution, store the sealed vial refrigerated at 2–8 °C (36–46 °F); for long-term storage the freezer is fine. Keep it away from light and heat.
After reconstitution with bacteriostatic water, keep the vial refrigerated at 2–8 °C and use it within the bacteriostatic window — commonly cited as up to ~28 days. Protect it from light, and never freeze a reconstituted peptide or put it through repeated freeze–thaw cycles, which degrade the peptide chain.
Bacteriostatic water (0.9% benzyl alcohol) is the preservative that lets a single vial be drawn from repeatedly; plain sterile water has no preservative. Inspect before use and discard any vial whose solution has turned cloudy or developed particulates.
