definitely! I've taken it on all of my vacations - always fun going through customs with a big bag of powder lol. But yes, you always want to have that steady stream of protein, regardless if you're not working out each day. Basically to maintain muscle mass and make sure you don't waste away your gains! Plus, if you're like me on vacation you're constantly on the go. Shakes are easy and quick and you're back to enjoying freedom!
