Why Shipping Conditions Matter
Peptides are sensitive molecules that can degrade rapidly under improper temperature and humidity conditions during shipping, compromising research quality.
Temperature Requirements
Lyophilized Peptides: Most freeze-dried peptides remain stable at room temperature for short periods (2-7 days) but benefit from cold chain shipping when possible.
Reconstituted Peptides: Must be shipped frozen or with adequate cold packs to maintain temperatures below 4°C throughout transit.
Proper Packaging Standards
Insulated Containers: Quality vendors use insulated boxes with appropriate thermal mass to maintain stable temperatures.
Cold Packs or Dry Ice: For temperature-sensitive peptides, vendors should include sufficient cooling materials for the expected transit time.
Moisture Protection: Peptides should be sealed against humidity with desiccant packets or vacuum-sealed packaging.
Shipping Time Considerations
Express Shipping: Reputable vendors often require expedited shipping for peptides, minimizing temperature exposure time.
Weekend Holds: Professional vendors avoid shipping peptides before weekends when packages might sit in warehouses.
Red Flags in Shipping
Be cautious of vendors using regular mail, no temperature control, or shipping without considering transit time and weather conditions.
Storage Upon Arrival
Immediately refrigerate or freeze peptides upon arrival and inspect packaging for signs of temperature compromise.
