Cold chain
An unbroken temperature-controlled supply chain for keeping peptides within a specified temperature range from manufacturing to administration. Critical for maintaining peptide stability during shipping and storage.

The conditions required to maintain peptide stability and potency. Lyophilized peptides should be stored at -20°C for long-term or 2–8°C for short-term. Reconstituted peptides must be refrigerated and used within 28 days.
StabilityA peptide’s resistance to chemical degradation over time. Affected by temperature, pH, light, and oxidation. Lyophilized peptides are most stable; reconstituted peptides should be refrigerated and used within 28 days.
DegradationThe breakdown of a peptide through chemical processes like oxidation, deamidation, or hydrolysis. Degredation reduces potency and may produce inactive or harmful byproducts. Proper storage conditions minimize degradation.
