Why Storage Rules Exist: The Chemistry Behind Stability Peptide degradation in solution occurs through three primary chemical pathways: hydrolysis (water cleaves the peptide backbone, most rapid at elevated temperature and acidic or alkaline pH), oxidation (methionine, cysteine, and tryptophan side chains react with dissolved oxygen or photocatalytic radicals), and deamidation (asparagine and glutamine residues lose an amide group, producing aspartate or glutamate and altering the peptide's charge and receptor binding)

Our team always recommends using a freezer for any lyophilized peptides you don't plan to use within the next couple of months
It activates melanocortin receptors, including MC3R and MC4R, which are primarily found in the central nervous system
