Research peptides should be stored in a cool, dry environment, ideally at -20°C (freezer) for long-term storage or at 4°C (refrigerator) for short-term use up to 4 weeks. Keep all vials away from direct sunlight, moisture, and heat. Once reconstituted, peptides should be stored at 4°C and used within 28 days.
