- Before choosing your cooling method, understand that the GHK-Cu form (lyophilized powder vs reconstituted solution) determines which system works. The table below shows temp range, duration, and TSA considerations for the five most common transport options.
- FRIO Cooling Wallet
- 18–26°C
- 24–48 hrs
- Compliant, no liquids
- Unreconstituted lyophilized powder only
- Works for powder; inadequate for reconstituted peptides (too warm)
- MedActiv Hard Cooler + Gel Packs
- 2–8°C
- 8–12 hrs (frozen packs)
- Compliant if gel packs frozen solid
- Reconstituted peptides, domestic flights under 8 hours
- Best consumer option for short flights; fails on delays or long connections
- Vacuum Insulated Thermos (Pre-Chilled)
- 4–6 hrs
- Compliant, no external power
- Reconstituted peptides, direct flights only
- Minimal protection; only for flights under 4 hours with no layover
- Cold Chain Courier (FedEx Clinical)
- −20 to +8°C
- 24–72 hrs
- Not applicable (shipped, not carried)
- International travel or itineraries over 10 hours
- Most reliable for long distances; high cost ($150–400 per shipment)
- Unreconstituted Powder in Carry-On (No Cooling)
- Room temp (up to 25°C tolerated for 48 hrs)
- Indefinite during travel
- Fully compliant
- Any flight length; reconstitute on arrival
- Eliminates all temperature risk during travel; requires bacteriostatic water at destination
