How do I travel with peptides and what are the TSA rules?

TSA allows injectable medications including peptides in carry-on bags and they are exempt from the 3.4-ounce liquid restriction when declared at security checkpoints. Unused syringes are permitted when accompanied by injectable medication, and ice packs or gel packs for cooling are allowed in frozen, partially frozen, or melted states. Keep peptides in original packaging with visible labels, pack them in accessible bags for easy inspection, and never check them in luggage where temperature fluctuations may cause damage. For international travel, research destination country regulations and carry prescription documentation.
