Lyophilized peptides should be stored in a cool, dry place away from direct sunlight. For long-term storage (months to years), we recommend storing them in a freezer at -20C or colder. Keep the vials sealed until ready to use, and allow them to reach room temperature before opening to prevent moisture condensation.

When stored properly at -20C in a sealed vial and protected from light and moisture, lyophilized peptides can maintain stability for 24 months or longer. Each product label provides a recommended use-by date based on stability testing data.

Once reconstituted with bacteriostatic water, peptides must be kept refrigerated between 2C and 8C (36F 46F). Avoid freezing reconstituted peptides as it can damage the molecular structure and reduce efficacy in research applications.

Reconstituted peptides stored in bacteriostatic water and refrigerated between 2C8C are generally stable for 46 weeks. This can vary by peptide structure; more sensitive sequences may degrade faster. Always follow best laboratory practices for your specific research application.

As our products are strictly for research purposes, we do not provide reconstitution guides, dosing instructions, or experimental protocols. Qualified researchers are expected to have the necessary scientific knowledge to handle these compounds appropriately within their specific experimental designs.
