                                According to manufacturers like GenScript, most lyophilized (freeze-dried) peptides can remain stable for several years when stored properly at -20°C. This longevity is crucial for anyone using peptide therapies, raising the important question: do peptides have an expiration date that impacts their effectiveness over time?
