            "q": "How should I store reconstituted peptides to prevent degradation?",
            "a": "Store reconstituted peptide solutions cold, in the dark, and sealed to slow the hydrolysis and oxidation that start degrading them immediately. Keep vials refrigerated at 2-8°C for short-term use, upright, in original packaging or an opaque container, and minimize time the vial sits open to air. For storage beyond a few weeks, freezing at -20°C or colder is better, though stability still varies by peptide and diluent. Avoid repeated freeze-thaw cycles by dividing solution into single-use aliquots at reconstitution time; each thaw-refreeze stresses the peptide structure. Bring bacteriostatic water to room temperature before mixing, use sterile air-tight stoppers, and write the reconstitution date and diluent on the vial, since degraded solutions can still look clear. Starting with a pure, well-characterized powder and a Certificate of Analysis also matters, since poor source material won't be fixed by good storage later."
