All peptides offered by Resolve Peptides are produced through the lyophilization (freeze-drying) process, a method that preserves molecular stability during handling and transport for approximately 3–4 months. Once reconstituted with bacteriostatic water, the solution must be stored under refrigeration to maintain integrity, where it generally remains viable for up to 30 days. Lyophilization, also referred to as cryodesiccation, is a specialized dehydration technique in which the compound is frozen and then placed under reduced pressure. This causes the frozen water content to sublimate directly from solid ice to vapor, leaving behind a stable, crystalline peptide powder. The resulting white, porous material can be kept at room temperature until reconstitution is required. After delivery, peptides should be safeguarded from light exposure and stored in a cool environment. For short-term use spanning several days to weeks, refrigeration at or below 4°C (39°F) is recommended. While lyophilized peptides may remain structurally intact at room temperature for weeks, cold storage provides added assurance of stability for ongoing research. For extended preservation lasting months or years, ultra-low freezing is preferred. Storage at –80°C (–112°F) offers the most reliable option for maintaining peptide quality and consistency over long durations. For detailed guidance on peptide handling and storage protocols, please refer to: Peptide Storage Information – resolvepeptides.com For extended preservation, particularly for storage spanning multiple months to years, peptides are best kept in ultra-low freezers at approximately –80°C (–112°F). Under these long-term conditions, structural stability is maximized, ensuring peptides retain their quality and suitability for future research applications.
