- Lyophilised peptide + passive cooling (FRIO wallet)
- Maintains 2–8°C for 24–36 hours with proper pre-activation
- Low. Recognized as medical cooling device, minimal scrutiny
- Flights ≤6 hours + 4-hour delay buffer
- Moderate. Depends on ambient cabin temperature and gel pack quality
- Best option for short domestic flights; cost-effective and TSA-compliant with minimal setup
- Lyophilised peptide + active cooling (USB refrigerator)
- Programmable 2–8°C with continuous monitoring; logs temperature excursions
- Moderate. Requires explanation of battery pack and device function
- 12–16 hours on portable battery; unlimited with AC access
- Low. Temperature control is precise and verifiable post-flight
- Recommended for international or multi-leg flights; higher cost justified by reliability and audit trail
- Pre-reconstituted peptide in any cooling method
- Requires uninterrupted 2–8°C; no tolerance for excursions above 10°C
- High. Liquid volumes trigger additional TSA screening; documentation must specify 'in-use' medical necessity
- Maximum 28 days if cold chain never breaks; realistically 6–8 hours in travel conditions
- Very high. Cabin pressure, vibration, and any temperature spike denatures the solution irreversibly
- Not viable for research transport; only appropriate for immediate clinical use within 4–6 hours of reconstitution
- Checked baggage (any form)
- Cargo hold temperatures range 10–35°C seasonally; no refrigeration available
- N/A. Bypasses TSA screening but violates storage requirements
- 0 hours. Peptide is considered compromised upon arrival
- Near-certain. Temperature excursions guaranteed; insurance and liability issues
- Never use checked baggage for temperature-sensitive peptides; this is a complete failure of protocol
