- Lyophilised powder in carry-on (room temp)
- Stable 48–72 hours at 15–25°C
- Low. Appears as white powder, requires clear labeling
- None if properly labeled
- Domestic flights under 48 hours where reconstitution happens at destination
- Lowest-risk option for short trips. No refrigeration = no temperature documentation burden.
- Reconstituted peptide in insulated cooler (carry-on)
- Requires gel packs replaced every 12–18 hours
- Moderate. Cooler triggers manual bag check in 40% of screenings
- Gel packs must be fully frozen at screening or count toward liquid limit
- Trips where immediate dosing access is required and hotel freezer access confirmed
- Best for active research protocols. Temperature maintenance is the critical failure point.
- Reconstituted peptide in checked baggage (hard-case cooler)
- High risk. Cargo hold temp varies 5–30°C depending on aircraft and season
- Low. Checked bags screened via CT, not manual inspection
- Airline baggage weight limits apply; dry ice requires pre-approval
- Long international flights where carry-on space is limited
- Avoid unless absolutely necessary. Temperature excursions in cargo hold frequently denature peptides.
- Overnight courier to destination (FedEx Clinical, UPS Temperature True)
- Maintains 2–8°C via active refrigeration and real-time monitoring
- Zero. Not subject to TSA
- Requires recipient address and signature; $80–$200 per shipment depending on distance
- Multi-week trips, international travel, or bulk transport
- Most reliable for high-value peptides or international destinations. Cost is justified by eliminated confiscation risk.
