How to Ship and Transport Peptides Safely
Proper shipping and transport protocols are essential to maintaining peptide integrity during transit. Whether receiving peptides from a supplier or moving them between research facilities, understanding temperature control and packaging requirements ensures your research compounds arrive in optimal condition.
Temperature During Shipping
Lyophilized peptides are more tolerant of temperature fluctuations during shipping than reconstituted peptides. Most lyophilized peptides can withstand 2-3 days of ambient temperature shipping without significant degradation. However, extended exposure to heat (above 30°C) can compromise integrity. Reputable suppliers like Proxiva Labs use insulated packaging with cold packs for warm-weather shipments.
Packaging Requirements
Proper peptide shipping packaging includes: insulated containers (styrofoam or thermal-lined mailers), gel ice packs for temperature-sensitive shipments, cushioning material to prevent vial breakage, and sealed plastic bags as secondary containment.
Receiving Your Peptide Order
When your peptides arrive: inspect packaging for damage, check that ice packs are still cool (indicates proper cold chain), move vials to proper storage immediately (refrigerator or freezer), and document any concerns with photos before contacting the supplier.
Transporting Between Facilities
For short transports (under 2 hours): a small insulated cooler with an ice pack is sufficient for lyophilized peptides. For reconstituted peptides: always use cold packs, minimize time out of refrigeration, and transport upright to prevent stopper contact.
Seasonal Considerations
Summer shipping poses the greatest risk. Request expedited shipping during hot months. Avoid Friday deliveries that could leave packages in hot warehouses over weekends. Winter cold is less concerning for lyophilized peptides but can freeze reconstituted solutions.
