- Lyophilized powder in original packaging (no cooling)
- Room temperature (18–24°C)
- 24–48 hours without degradation
- Minimal screening. Not subject to liquids rule, requires documentation
- Acceptable for flights under 12 hours with minimal layover time if starting with fresh lyophilized product
- FRIO evaporative wallet
- 18–26°C
- 24–48 hours with proper activation
- Requires explanation but poses no screening difficulty
- Insufficient for reconstituted TB-4. Acceptable for lyophilized backup or short domestic flights only
- Insulin cooling case with gel packs
- 2–8°C
- 8–12 hours depending on ambient temperature
- Gel packs are TSA-approved, case will be opened and inspected
- Best option for reconstituted peptides on flights under 8 hours. Proven cold chain maintenance with verification
- Insulated container with dry ice
- −78°C
- 24+ hours
- Dry ice is restricted to 5.5 lbs per passenger, requires airline notification 24 hours in advance, considered hazardous material
- Overkill for TB-4. Dry ice protocols apply to ultra-low temperature biologicals, not standard peptide transport
