Traveled all over the world with TrueNutrition RTDS. Little plastic milk bottles of 50 grams of protein each. Give one to the flight attendant during drink service, they top if off with water and there I go, 50 grams of protein.
Then discard, perfect for travel. As a competitive bodybuilder, not missing a meal is so important and these little babbies make my life so much easier.
