How are synthetic peptides stored to maintain stability?

Lyophilized (freeze-dried) peptides are the most stable form for long-term storage. In powder form, most synthetic peptides remain stable for 12–24 months when stored at −20 °C in a desiccated, light-protected environment. Reconstitution with sterile bacteriostatic water — which contains 0.9% benzyl alcohol as a preservative — allows repeated use from a single vial over several weeks when refrigerated at 2–8 °C. Peptides containing cysteine, methionine, or tryptophan residues may require additional antioxidant precautions and have shorter reconstituted half-lives.
