KNOWLEDGE BASE
Lyophilized Powder
Lyophilized peptides are produced through a freeze-drying process that removes moisture to help maintain molecular stability during storage. Peptides may be supplied in either liquid or lyophilized powder form, depending on the formulation and intended use. Lyophilized presentations can offer superior structural preservation and higher potency by removing moisture that causes degradation.
