Peptide Storage Guide
Proper storage keeps your peptides stable and effective. Follow these guidelines.
Powder form (lyophilized)
Store sealed vials in the freezer at -20°C, away from light and moisture. In these conditions, lyophilized peptides remain stable for months.
Keep vials in their original packaging until you are ready to use them.
Reconstitution
Let the vial warm to room temperature before reconstituting. Dispense bacteriostatic water slowly along the inner wall of the vial using appropriate laboratory technique, not directly onto the powder. Swirl gently to dissolve. Never shake the vial.
After reconstitution
Store reconstituted peptides in the fridge at 2-8°C and use within 28 days. Do not freeze after reconstitution.
Shipping stability
Your order travels inside Egypt as a lyophilised (freeze-dried) powder in a sealed vial. In this form, the product is stable at ambient temperature for the 3 to 5 business days of delivery, even in summer. The powder only needs cold storage after it has been reconstituted.
Store the sealed vials in the freezer at -20°C as soon as they arrive, and they are ready for your research when you need them.
Quick summary
- Powder: -20°C freezer, away from light
- Reconstituted: 2-8°C fridge, use within 28 days
- Never: shake, freeze after mixing, or expose to direct light
