Lyophilized (powder) peptides should be stored in a cool, dry place away from direct sunlight. For long-term storage, refrigeration at 2–8°C is recommended. Once reconstituted, peptides must be refrigerated and used promptly.

Most lyophilized peptides remain stable for 12–24 months when stored properly in sealed vials at the recommended temperature.

Lyophilized (powder) peptides can be frozen for extended storage. However, reconstituted peptides should not be frozen as this can degrade their integrity.

Reconstitution should only be performed by qualified researchers using bacteriostatic water or appropriate sterile solvents under aseptic conditions. General handling guidance is included with all orders.
