Storage & Stability
Our peptides are produced using a specialized freeze-drying process known as lyophilization. This process removes moisture from the peptide while preserving its structure, helping maintain stability during storage and shipping.
Before reconstitution, lyophilized peptides are typically presented as a dry, white powder or cake inside the vial. In this form, they are generally more stable than liquid peptides and can better tolerate short-term temperature changes that may occur during transit.
Once received, peptides should be stored in a cool, dry place away from direct light. For short-term storage, refrigeration at approximately 4°C / 39°F is commonly recommended. For longer-term storage, keeping lyophilized peptides frozen may help preserve their stability over time.
After the peptide is reconstituted with bacteriostatic water, it should be stored in the refrigerator and protected from light. Reconstituted peptides are generally recommended for use within 30 days to help maintain quality and stability.
In simple terms:
Lyophilized peptides are designed to remain stable while dry, but once mixed, they should be kept cold and handled with care.
